SSL backend error when using OpenSSL

Question

I was trying to install pycurl in a virtualenv using pip and I got this error

ImportError: pycurl: libcurl link-time ssl backend (openssl) is different from         


        

Answer 1

With pip 7.1 you can put the following in your requirements file:

pycurl==7.19.5.1 --global-option="--with-nss"

Simply replace nss with the relevant ssl backend library.

Answer 2

pip install -U pip

if [ "$(curl --version | grep NSS 2>/dev/null)" ]; then
    pip install --compile --install-option="--with-nss" pycurl
else
    pip install --compile --install-option="--with-openssl" pycurl
fi
