Python not working (ImportError) when I try to use pip on Mac OSX

Question

I'm trying to install gym for my assignment and did pip install gym and got this output. Anaconda and jupyter notebook also do not work when it used to work perfectly before. I tried uninstalling python and reinstalling but that did not solve the issue. Would anyone know how to fix this?

Note: I use Mac OS

EDIT: This forum solved it for me: Python referencing old SSL version .

Answer 1

The python2.7 package is dependent to the libssl1_0_0 package (openssl_1.0 runtime librairies).

Install it, and add the /usr/local/ssl/lib directory in $LD_LIBRARY_PATH environnent variable.

To set it,

export LD_LIBRARY_PATH="/usr/local/ssl/lib"

Can you also update me on the output of running this cmd if the earlier solution doesn't work python -c "import ssl; print ssl.OPENSSL_VERSION"

Answer 2

Literally dealing with the same issue today, its an issue with openssl but im still working to resolve it

*edit - actually this just worked for me, brew switch openssl 1.0.2s youre switching to an older version of openssl. pip and everything works for me now
