hash md5 error on Mac

[thundertrick]

I install autojump and it works quite well until today. Every time I open a directory a mass of python error msg is printed to the terminal. I install buck and watchman with homebrew today.

If I uninstall autojump, the error msg dismiss. Is there any way to fix it?

The detail of error msg is as following:

[thundertrick]

The reason seems to be OS X use ssl lib of its own instead of openssl. Thus if we brew install openssl, the two lib conflict. Walk around can be found here: https://github.com/dotnet/cli/issues/3964#issuecomment-236493536

This issue can be close now, thanks.

Thanks for sharing the root cause.

Same issue, works after removing python@2 brew uninstall python@2.

[HSHPANDEY]

why did reinstalling python worked!

[HuangHongRui]

因为俺使用的是：pyenv.

所以使用 pyenv install -f 2.7.17 来解决我的问题

then

brew reinstall python@2.rb

It works for me to resolve the error "ERROR:root:code for hash md5 was not found.". Just a little confuse to brew version control.

[chrisnankervis]

@slixurd your solution worked for me as well, thank you!

I also learned that you can install a package via brew from a file, nifty solution 👍

sorry @slixurd @chrisnankervis where exactly do i have to save that ruby script you link to above on my computer? thanks

Workaround for error installing openvFor Mac - $ Python macbookpro$ pip install opencv-python ERROR:root:code for hash md5 was not found.

Try these steps:

$brew switch openssl 1.0.2r

then activate your environment and try $ python -c "import hashlib;m=hashlib.md5();print(m.hexdigest())"

Then pip install opencv-python
