"ERROR:root:code for hash md5 was not found" when using any hg mercurial commands

When trying to use any hg Mercurial commands on the console, I keep getting this error. I installed Python using Homebrew and I am running Mac OS Catalina v. 10.15.1.

Any reference would be appreciated. Here is the error I'm getting:

hg commit --amend

I also tried following the instruction on this issue but none of the solutions seem to work 

brew link openssl --force

On macOS Sonoma (14.5), This worked for me: download the last release of python 2 from this website

My problem was multiple versions of python installed (python was still aliased to python2 but i wanted pip to use python3). i also have a python3 bin installed on my system

$ python -V
Python 2

# use pip with python3
$ python3 -m pip install fish

One reason: an older libssl is needed

When this error occurs, Python is not able to import the _hashlib.py module. One reason for this is libssl changing its ABI during version transition. This affects at least Python2.7.

Solution: Download libssl version 1.1.0, compile and install it in a different location. Then tell python during its configure process to use this old libssl library.

For me a non standard prefix like ./configure --prefix=/home/anyuser/python for the python code tree was sufficient (i installed libssl to /usr/local), as the parallel installed old libssl library in a usual place (/usr/local) was automatically found and used during the configuration and compile process.

This is a good example for why having /usr and /usr/local directories in parallel. I always wondered about that. /usr for the standard system stuff, /usr/local for additional parallel things.

After compiling python2.7 there appears a summary in the terminal where it tells you what went wrong during compilaton/linking. There should be no sign of a missed _hashlib anymore.

This fixed it for me, I use port not brew:

sudo port upgrade openssl

In my case, my environment was using python 2.7.15. When I switched my pyenv version to 2.7.18 it just worked.

For my case, I just reinstall python2 using pyenv

pyenv uninstall 2.7.18
pyenv install 2.7.18

then everything seems to hooks up.

My problem was having pyenv installed and pointing to an old python 2 version

Uninstall python@2 (python2 was EOL since Jan 1st, 2020)

$ brew uninstall python@2
Uninstalling /usr/local/Cellar/python@2/2.7.15_1... (4,169 files, 76.0MB)

then

$ pyenv versions
  system
* 2.7.12 (set by /Users/admin/.python-version)
  3.4.5
  3.7.7

$ pyenv local system
$ pyenv global system

After installing openssl I got the same problem. This answer didn't help me, but after manual linking of libcrypto.1.1.dylib and libssl.1.1.dylib everything start working. In my case it was:

ln -s /usr/local/opt/openssl/lib/libcrypto.1.1.dylib /usr/local/lib
ln -s /usr/local/opt/openssl/lib/libssl.1.1.dylib /usr/local/lib

On macOS Mojave (10.14.6), this worked for me:

  • Save the file as [email protected] in your current directory.
  • brew reinstall [email protected]
  • I was using virtual environments, so I had to link them back to /usr/local/bin/python and /usr/local/bin/pip for python and pip binaries.

The next solution worked for me on MacOS Catalina:

  1. Unlink openssl
brew unlink openssl
  1. Reinstall python 2.7 (removed from homebrew and can't be installed via brew install python@2)
brew tap-new <user>/homebrew-python2
brew extract python@2 <user>/homebrew-python2
brew reinstall /usr/local/Homebrew/Library/Taps/<user>/homebrew-python2/Formula/[email protected]

I had this issue recently (2020, May) with Google's GCP CLI. It also works on the obsolete Python 2.7.

This is a borked Python 2 installation problem. mBrew no longer correctly installs Python 2 gracefully, as no one cares about abondonware.

Conda still installs Python 2 in an environment; I did that.

Running brew reinstall python@2 didn't work for my existing Python 2.7 virtual environments. Inside them there were still ERROR:root:code for hash sha1 was not found errors.

I encountered this problem after I ran brew upgrade openssl. And here's the fix:

$ ls /usr/local/Cellar/openssl

...which shows

1.0.2t

According to the existing version, run:

$ brew switch openssl 1.0.2t

...which shows

Cleaning /usr/local/Cellar/openssl/1.0.2t
Opt link created for /usr/local/Cellar/openssl/1.0.2t

After that, run the following command in a Python 2.7 virtualenv:

(my-venv) $ python -c "import hashlib;m=hashlib.md5();print(m.hexdigest())"

...which shows

d41d8cd98f00b204e9800998ecf8427e

No more errors.

When I would import hashlib I would see an error message stating that hash md5 was not found.

I was able to fix this problem by first unlinking openssl: brew unlink openssl

Then I uninstalled python 2.7 using MacPorts: sudo port uninstall python27

Then I installed python 2.7 using MacPorts: sudo port install python27

Now importing hashlib works :)

The case for me is that when I install dependencies of a django web app, it messes up the environment. When I type cd, it shows the same error.

The problem was the openssl library, it can not find the correct ones.

If you are on Macintosh, you can type

ls /usr/local/Cellar/openssl

to see all the versions,

brew switch openssl 1.0.XXXX

to choose the available openssl version.

Then the error is gone :)

Managed to fix this by first unlinking openssl 

brew unlink openssl

And then reinstalling python

brew reinstall python@2

I also noticed that when running 'brew doctor' there was a warning related to an openssl folder found in /usr/local/include/node/. I deleted this folder before running the above commands (not sure if related)
