I’m trying to execute a Python script on my Mac but keep running into this frustrating error message. The issue seems to be related to pycurl and SSL backend configuration problems.
The exact error I’m getting is:
ImportError: pycurl: libcurl link-time ssl backend (openssl) is different from compile-time ssl backend (none/other)
I’m working on macOS High Sierra (version 10.13.2) with Python 2.7 installed. This error appears every time I try to run my script and it’s preventing me from moving forward with my project. Has anyone encountered this SSL backend mismatch issue before? I’m not sure if this is a installation problem or configuration issue with my development environment.
try buildin pycurl from source instead of using pip - had same issue on my macbook pro. download the tarball and export LDFLAGS=“-L/usr/local/opt/openssl/lib” CPPFLAGS=“-I/usr/local/opt/openssl/include” before runnin python setup.py install. worked for me after fightin with it for hours
This SSL backend mismatch occurs when pycurl was compiled against a different SSL library than what libcurl is currently using. The solution involves reinstalling pycurl with proper SSL backend configuration. First, uninstall the existing pycurl installation using pip uninstall pycurl. Then reinstall it with explicit SSL backend specification by running pip install --compile --install-option="--with-openssl" --install-option="--openssl-dir=/usr/local/opt/openssl" pycurl. If you are using Homebrew, ensure OpenSSL is properly installed with brew install openssl. You may also need to set environment variables like PYCURL_SSL_LIBRARY=openssl before the installation. This approach forces pycurl to compile against the same OpenSSL backend that libcurl expects, resolving the mismatch error.
hmm, are you using any virtual environments or conda? sometimes this happens when theres conflicting ssl libraries across different python setups. what does which python and pip show pycurl tell you? might help narrow down whats going on with your setup
