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
Warning: Refusing to link macOS-provided 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"

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.
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)
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 :)
Just uninstall python2
$ brew uninstall python@2
If there is any error :
$ brew uninstall --ignore-dependencies python@2
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
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.
The next solution worked for me on MacOS Catalina:
- Unlink openssl
brew unlink openssl
- 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/
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 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
# use pip with python3
$ python3 -m pip install fish

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 :)
On macOS Mojave (10.14.6), this worked for me:
- Save the file as in your current directory.
- brew reinstall
- I was using virtual environments, so I had to link them back to
/usr/local/bin/pythonand/usr/local/bin/pipforpythonandpipbinaries.
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
In my case, my environment was using python 2.7.15. When I switched my pyenv version to 2.7.18 it just worked.
This fixed it for me, I use port not brew:
sudo port upgrade openssl
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.
