pip: no module named _internal

I have a problem when I try to use pip in any way. I'm using Ubuntu 16.04.4

I should say that I've used it already, and I never had any problem, but starting today when I use any command I always get the same error (as an example using pip --upgrade).

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 7, in <module>
    from pip._internal import main
ImportError: No module named _internal

I have tried doing sudo apt-get remove python-pip followed by sudo apt-get install python-pip but nothing changed.

I got this issue after trying to upgrade to python 3.12

The fix for me was curl -sS https://bootstrap.pypa.io/get-pip.py | python3.12

Test with pip3.12 -v

Then issue echo "alias pip=$(which pip3.12)" >> ~/.bashrc and don't forget source ~/.bashrc

On Mac and MiniConda, I used the following command and it worked:

 conda activate /opt/miniconda3 /opt/miniconda3/bin/conda install -p /opt/miniconda3 pip -y

I have fixed this error by running the following commands:

sudo apt remove python-pip
wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

It will remove the previously installed pip and reinstall it.

Please verify the directory permission for /usr/local/lib/python3.9/ and modify the permission using chown command

sudo chown -R centos:centos /usr/local/lib/python3.9/

I did

 py -m install packagename

instead of

pip install packagename

I also had this problem because some of my folders got corrupted due to a hard disk failure, due to this the pip_internal folder also got corrupted. To fix this, I first ran a disk repair restart so that the corrupted folders get removed from the drive, after that I deleted the whole pip folder from the site packages (Python>Lib>site-packages>pip).

Then I ran this command in terminal: python -m ensurepip and it reinstalled the whole pip package. After this pip is working fine.

In some cases, this can occur because pip was upgraded by the root user, and the upgrade - for some reason - defaults to creating non-all-user-accessible subdirectories and files in the "site-packages" directory.

To check if this is the case, we need locate the site-packages directory, e.g. with python3, running this command:

python -c 'import sysconfig; print(sysconfig.get_paths()["purelib"])'

Now let's check whether there are pip-related subdirs there with problematic permissions:

site_pkg_dirs=$(python -c 'import sysconfig; print(sysconfig.get_paths()["purelib"])')
pushd ${site_pkg_dirs}
ls -ld pip*
popd

If the output is empty - then this answer won't solve your problem; sorry :-(

But if the output is not empty, e.g.:

drwxr-x--- 5 root root 111 Jan 01 00:00 pip
drwxr-x--- 2 root root 170 Jan 01 00:00 pip-21.3.1.dist-info

then carefully examine the permission listing on each: If the "all" permission triplet doesn't have r and x - you need to add those; and since this same problem might be manifested for other packages, let's be more thorough about it:

find ${site_pkg_dirs} -type d | chmod a+rx
find ${site_pkg_dirs} -type f | chmod a+r

this ensures all subdirectories in your site package directory are readable and recursable, and that all files in those subdirectories are readable. Specifically, this will apply to the pip-related subdirs, which should now look like this when you ls -l them:

drwxr-xr-x 5 root root 111 Jan 01 00:00 pip
drwxr-xr-x 2 root root 170 Jan 01 00:00 pip-21.3.1.dist-info

This should solve your pip troubles! Let's check: If you now run

pip show pip

you should get something like :

$ pip3.6 show pip

pip is not being installed properly on your "user", so try the following :

sudo python3 -m pip install --user --upgrade pip

windows OS：

1、download this file：“https://bootstrap.pypa.io/get-pip.py”，Put it in this（E:\PythonProject\venv\Scripts’（Your virtual environment installation directory）） directory！
2、open ‘Windows PowerShell’
3、cd ‘E:\PythonProject\venv\Scripts’（Your virtual environment installation directory）
4、run cmd ‘py get-pip.py’

An answer from askUbuntu works.

For pip2.7, you can at first curl https://bootstrap.pypa.io/pip/2.7/get-pip.py -o get-pip.py, then python2.7 get-pip.py --force-reinstall to reinstall pip.

Problem solved. Also works for python3.

Are you using python 2 or python 3? The following commands could be different!

run python3 -m pip --version to see if you have pip installed.
if yes, run python3 -m pip install --upgrade pip.
if no, run sudo apt-get install python3-pip, and do it again.

These often comes from using pip to "update" system installed pip, and/or having multiple pip installs under user. My solution was to clean out the multiple installed pips under user, reinstall pip repo, then "pip install --user pip" as above.

See: https://github.com/pypa/pip/issues/5599 for an official complete discussion and fixes for the problem.

Refer to this issue list

sudo easy_install pip

works for me under Mac OS

For python3, may try sudo easy_install-3.x pip depends on the python 3.x version. Or python3 -m pip install --user --upgrade pip

This solution works for me:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py --force-reinstall

or use sudo for elevated permissions (sudo python3 get-pip.py --force-reinstall).

Of course, you can also use python instead of python3 ;)

My solution is adding import pip to the script linked to the pip/pip3 commands.

Firstly, open the file (e.g. /usr/local/bin/pip) with your favorite text editor and the sudo mode. For example, I use sudo vim /usr/local/bin/pip to open the script file.

You will obtain some file as following:

import re
import sys

from pip._internal import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

Afterwards, insert the statement import pip just before the from pip._internal import main then the issue is resolved.

I met the same error on Windows when I tried to install a package via pip3:

Traceback (most recent call last):
  File "d:\anaconda\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "d:\anaconda\lib\runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "D:\Anaconda\Scripts\pip3.6.exe\__main__.py", line 5, in <module>
ModuleNotFoundError: No module named 'pip._internal'

My python is installed via Anaconda. I solved this issue by reinstalling pip via conda:

conda install pip

After that, pip returns to normal.

For the current user only:

easy_install --user pip

python -m pip install --upgrade --user pip

The second may give /usr/bin/python: No module named pip Even if which pip finds the module named pip. In this case try the easy_install

my solution: first step like most other answer:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python2.7 get-pip.py --force-reinstall

second, add soft link

sudo ln -s /usr/local/bin/pip /usr/bin/pip

I just encountered the same problem and in my case, it turns out this is a conflict between the python installation in my virtualenv and the site-wide python (Ubuntu). What solves it for me is to run pip in this way, to force usage of the correct python installation (in my vortualenv):

python3 -m pip install PACKAGE

instead of

pip3 install PACKAGE

I realised this when I tried to follow some of the answers here that suggest re-installing pip and the error output I got was pointing to an existing site-wide python library path although I had activated my virtualenv. Worth trying before deleting and re-installing stuff.

Nothing worked for me, but only one thing: I used sudo in front of the command and it is working fine.

This issue maybe due to common user do not have privilege to access packages py file.
1. root user can run 'pip list'
2. other common user cannot run 'pip list'

[~]$ pip list
Traceback (most recent call last):
  File "/usr/bin/pip", line 7, in <module>
from pip._internal import main
ImportError: No module named pip._internal

Check pip py file privilege.

[root@]# ll /usr/lib/python2.7/site-packages/pip/  
合計 24  
-rw-------  1 root root   24  6月  7 16:57 __init__.py  
-rw-------  1 root root  163  6月  7 16:57 __init__.pyc  
-rw-------  1 root root  629  6月  7 16:57 __main__.py  
-rw-------  1 root root  510  6月  7 16:57 __main__.pyc  
drwx------  8 root root 4096  6月  7 16:57 _internal  
drwx------ 18 root root 4096  6月  7 16:57 _vendor

solution : root user login and run

chmod -R 755 /usr/lib/python2.7

fix this issue.

Its probably due to a version conflict, try to run this, it will remove the older pip somehow.

sudo apt remove python pip

I've seen this issue when PYTHONPATH was set to include the built-in site-packages directory. Since Python looks there automatically it is unnecessary and can be removed.
