pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available

Question

I am using Python 3.6. When I try to install "modules" using pip3, I face this issue:

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available

Answer 1

On macOSX, I had this issue after upgrading my homebrew packages. openssl was upgraded from openssl1.1 to openssl@3.

The solution was to remove openssl@3, and install openssl@1.1 with homebrew:

brew remove openssl@3

brew install openssl@1.1

Answer 2

I exited my virtual environment and upgraded pip.

Answer 3

I'm using Windows 10 and installed Miniconda 3 with Python 3.7.

I solved this error by following this https://github.com/conda/conda/issues/8273

Specifically, I copied the following files from C:\Users\<user>\Miniconda3\Library\bin to C:\Users\<user>\Miniconda3\DLLs:

• libcrypto-1_1-x64.dll
• libcrypto-1_1-x64.pdb
• libssl-1_1-x64.dll
• libssl-1_1-x64.pdb

If you work in an environment, it will be from C:\Users\<user>\Miniconda3\envs\<name>\Library\bin to C:\Users\<user>\Miniconda3\envs\<name>\DLLs:

Answer 4

This issue occurs when we compile python from source without installing some packages that helps with ssl. Here is how to fix this in a Debian based Linux system.

sudo apt install build-essential pkg-config zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev libbz2-dev
./configure --enable-optimizations
make -j 4 
sudo make altinstall

Note that -j 4 specifies that I want to use 4 CPU threads. You can check how many threads your CPU has by running nproc

Answer 5

For Debian users, the following may be of use:

sudo apt install libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev libtk8.6 libgdm-dev libdb4o-cil-dev libpcap-dev

Then cd to the folder with the Python 3.X library source code and run:

./configure
make
sudo make install

Answer 6

Even after trying all the above steps, i was getting the same error. So while we work in a lab and have authorised access to Internet,the issue was with old versions on servers. So i created a virtual environment and placed all my imported modules there. Gave all the necessary permission to the file and the user. Then i gave the internet access to the server system. It worked fine. Try checking for any access and permission issue you might have. Hope it helps. Thanks.

Answer 7

After trying to compile python myself and still lacking the ssl module, i finally tried to just install the missing module from apt like this:

apt install python3-openssl

Answer 8

Install openssl first.

If you are facing this issue in conda environment, you can install openssl using conda install -c anaconda openssl. It enables ssl for you!

Answer 9

Worked for me.

pkg install openssl

Use this to enable ssl.

Answer 10

I was getting the same error:

WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/pb-tool/

In Anaconda I did it with this command:

conda install anaconda-navigator

It was mentioned in this article : pip is configured with locations that require TLS/SSL however the ssl module in Python is not available

Answer 11

macOS, pyenv

In case of your python being an pyenv installed one, where pyenv is installed with homebrew on macOS, there might me a newer version available which fixes this:

$ brew update && brew upgrade pyenv

Then reinstalling the python version:

$ pyenv install 3.7.2
pyenv: /Users/luckydonald/.pyenv/versions/3.7.2 already exists
continue with installation? (y/N) 

Note, it is a bit dirty to overwrite the existing python install like that, but in my case it did work out. Probably cleaner to delete it and then recreate it properly.

Answer 12

MAC OS

I had the same problem on Mac OS(Mojave) and solved the problem as mentioned on this link - Openssl issue.

1. If you do not have Homebrew or don't know what is Homebrew:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Or if you already have Homebrew installed:

brew update && brew upgrade
brew uninstall --ignore-dependencies openssl; brew install https://github.com/tebelorg/Tump/releases/download/v1.0.0/openssl.rb

Update: Keep in mind, that I had to use --ignore-dependencies flag, because other packages installed that depend on OpenSSL.

Additional if the problem is caused after using pyenv, you can fix it by using:

brew reinstall python

Answer 13

Worked for me.

sudo apt-get install libssl-dev

Use this to enable ssl for pip. Let me know if someone encounters issues.

Answer 14

If you've installed anaconda via scoop, and encounter this error while using pip from within a conda environment you can resolve it by...

1. Adding these to your path

C:\Users\YOUR_USERNAME\scoop\apps\anaconda3\current
C:\Users\YOUR_USERNAME\scoop\apps\anaconda3\current\Scripts
C:\Users\YOUR_USERNAME\scoop\apps\anaconda3\current\Library
C:\Users\YOUR_USERNAME\scoop\apps\anaconda3\current\Library\bin

2. Installing openssl via scoop

scoop install openssl

3. And copying the following DLLs from ..\anaconda3\Library\bin to ..\anaconda3\DLLs

Answer 15

For Miniconda3 under Windows 10 with python=3.7.5 I tried all above suggestions; nothing worked. I had to downgrade to python=3.7.0 which solved the issue

conda install python=3.7.0

Obviously this is quite messy. The answers suggest that an upgrade to 3.8.5 might also work but this had too many side effects in my env.

Answer 16

In my case I was running into issues with my $PATH on Linux. This can also happen on MacOS.

Check to see if /usr/bin/pip3 install package_name_goes_here works for you. If so then run which pip3 this will tell you which is the first directory that pip3 is installed in.

If it is something like /usr/local/bin/pip3 which is different from /usr/bin/pip3 then you may need to adjust your $PATH.

Run echo $PATH and copy the result.

The PATH is simply a colon separated list of directories that contain directories. Bash will always return the first instance of the program that you are attempting to execute. Move all the system directories upfront. Here is a list of some of the system directories:

/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin

If that fails then verify you have openssl installed by running openssl version -a if not then install openssl.

Answer 17

In Windows 10 SQL Server 19 the solution is known.

Copy the following files:

• libssl-1_1-x64.dll
• libcrypto-1_1-x64.dll

from the folder

C:\Program Files\Microsoft SQL Server\MSSSQL15.MSSQLSERVER\PYTHON_SERVICES\Library\bin

to the folder

C:\Program Files\Microsoft SQL Server\MSSSQL15.MSSQLSERVER\PYTHON_SERVICES\DLLs

Then open a new DOS command shell prompt.

Answer 18

I simply solved the problem with following command:

brew upgrade python@3.9

SSL is included by default on this version!

Answer 19

I had the same issue and it was because I changed the folder of the environment. I just removed the env and reinstalled everything.

Answer 20

I got into this problem using Ubuntu, pyenv and Python 3.8.1 managed by pyenv. There was actually no way to get pip to work correctly, since every time I tried to install anything, including pip itself, the same error showed up. Final solution was to install, via pyenv, a newer version, in this case 3.8.6. Apparently, from 3.8.4 Python is prepared to run SSL/TLS out of the box, so everything worked fine.

Answer 21

For Windows 10 if you want use pip in normal cmd, not only in Anaconda prompt. you need add 3 environment paths. like the followings:

D:\Anaconda3 
D:\Anaconda3\Scripts
D:\Anaconda3\Library\bin 

most people only add D:\Anaconda3\Scripts

Answer 22

I am on macOS and I had used brew but what Vaulstein mentioned in his answer didn't cover my case.

I run the following commands to make sure my current python was not installed by brew

brew list | grep python           
python
python@2

brew info python
python@3.8: stable 3.8.3 (bottled)
Interpreted, interactive, object-oriented programming language
https://www.python.org/
Not installed
... 

So I download the latest 3.8.5 from https://www.python.org/ and when installing it I saw following information

Certificate verification and OpenSSL

This package includes its own private copy of OpenSSL 1.1.1. The trust certificates in system and user keychains managed by the Keychain Access application and the security command line utility are not used as defaults by the Python ssl module

After installed 3.8.5 it fixed the problem.

Answer 23

In my case, I reinstalled Python. It solved the problem.

brew reinstall python

Answer 24

You could try brew link and it will show you the proper instruction:

$ brew link openssl --force
Warning: Refusing to link macOS provided/shadowed software: openssl@1.1
If you need to have openssl@1.1 first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc

For compilers to find openssl@1.1 you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"

For pkg-config to find openssl@1.1 you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"

Answer 25

Newest Python 3.8.4 or higher should able to support https protocol out of box. If you still have old python installation on your pc - either download & install python3 manually, or using Chocolatey:

If you don't have Chocolatey, install it - from here: https://chocolatey.org/docs/installation

You can just copy paste one command line liner and execute it from command prompt with elevated priviledges.

choco install python3

if you don't have python3 installed, or you you have it installed - then:

choco upgrade python3

Notice also that you can use also anaconda distribution, as it has built-in python with https support, but this rather ancient instructions, no need to follow them anymore.

Install anaconda, using command line:

choco install anaconda3

Set environment variables:

set PATH=C:\tools\Anaconda3\Scripts;C:\tools\Anaconda3;C:\tools\Anaconda3\Library\bin;%PATH%

and then run command which failed. In my case it was:

pip install conan

Anaconda uses separate python installation, and pip is also anaconda specific.

Answer 26

The issue is due to OpenSSL package is missing on your PC.

If pip install openpyxl also gives error.

you can fix this by installing OpenSSL(Win64 OpenSSL v1.1.1g) from below site :

slproweb.com/products/Win32OpenSSL.html

Restart the IDE you are using, for changes to be in effect.

Answer 27

Similar to the above solution reinstall the python version with pyenv.

Somehow, I upgraded my openssl which broke the pyenv version python.

pyenv install 3.6.8
python-build: use openssl@1.1 from homebrew
python-build: use readline from homebrew
...

The first line says it relies on the homebrew openssl.

Answer 28

You’d try from Anaconda Prompt.

You will see (base), now upgrade pip. Example:

(base) C:\Users\Tom>cd ..

(base) C:\Users>cd ..

(base) C:\>python -m pip install --upgrade pip
Requirement already up-to-date: pip in g:\anaconda3\lib\site-packages (20.0.2)

(base) C:\>pip -V
pip 20.0.2 from G:\Anaconda3\lib\site-packages\pip (python 3.7)

# Try install
(base) C:\>pip install selenium

This takes a longer time, but will also install or upgrade SSL libraries that Anaconda uses internally. Keep Going here

Answer 29

The problem probably comes from your installed openssl package version. That was the case for me and I fixed this issue just upgrading it. I'm on Mac OS, using brew :

brew upgrade openssl

If you installed python with brew, this should directly fix the issue with it, as python is dependent on openssl

Answer 30

Fixed this without having to change anything related to TSL/SSL.

I was trying to see if the same thing was happening to pip, and saw that pip was broken. Did some digging and realized it's probably caused by Homebrew deleted python@2 on February 1st, 2020.

Running brew uninstall python@2 to delete python2 installed by Homebrew.

Destroyed the virtual env created using python3 and created a new one.
pip3 installing works fine again.
