Amazon Linux -> ImportError: No module named cryptography.hazmat.bindings.openssl.binding


#1

Hello friends, i have exactly the same problem this guy had:

About 6 months ago i successfully created my cert, on same distro, same instance.
…Amazon Linux

And know im trying to renew, or create a new certified, but i received this error:
ImportError: No module named cryptography.hazmat.bindings.openssl.binding

curl -O https://dl.eff.org/certbot-auto
chmod +x certbot-auto
mv certbot-auto /usr/local/bin/certbot-auto
certbot-auto certonly --standalone -d test.com.br -d www.test.com.br

I did what he did:
pip install cryptography
But i couldn’t find which folders should i use this:
ln -s dist-packages site-packages

Can someone help me?

Oi @xinxilas,

In the case of the user from the other thread, it was probably /usr/lib64/python2.7 (although depending on the architecture and operating system configuration, I could imagine that it could instead be /usr/lib32/python2.7 or /usr/lib/python2.7).

I don’t know the details of the packaging issue for which this is supposed to be a solution, I’m just trying to reproduce what the user in the other thread did. :slight_smile:

I have these dist-packages:
./opt/eff.org/certbot/venv/lib64/python2.7/dist-packages
./opt/eff.org/certbot/venv/lib/python2.7/site-packages/dist-packages
./opt/eff.org/certbot/venv/lib/python2.7/dist-packages
./usr/lib64/python2.7/dist-packages
./usr/lib/python2.7/dist-packages

And these site-packages
./opt/eff.org/certbot/venv/lib64/python2.7/site-packages
./opt/eff.org/certbot/venv/lib/python2.7/site-packages
./usr/local/lib64/python2.7/site-packages
./usr/local/lib/python2.7/site-packages
./usr/lib64/python2.7/site-packages
./usr/lib/python2.7/site-packages

Solved:

Also, I did not tried another workaround but it looks it works too:
/opt/eff.org/certbot/venv/local/bin/pip install cryptography interface
