SSL backend error when using OpenSSL

by

for most people

After reading their INSTALLATION file, I was able to solve my problem by setting an environment variable and did a reinstall

# remove existing `pycurl` installation 
pip uninstall pycurl

# export variable with your link-time ssl backend (which is openssl above)
export PYCURL_SSL_LIBRARY=openssl

# then, re-install `pycurl` with **no cache**
pip install pycurl --no-cache-dir

There could be other solution out there but this works perfectly for me on a virtualenv and pip installation.

Some people have a different error message complaining about nss instead of openssl

ImportError: pycurl: libcurl link-time ssl backend (nss)

(the key part is nss) so you have to do something different for this error message:

pip uninstall pycurl
pip install --no-cache-dir --compile --compile-options="--with-nss" pycurl
