pip install pycurl 错误
pip uninstall pycurl export PYCURL_SSL_LIBRARY=nss pip install pycurl
helloworld2013‘s answer is correct, but the key is matching the SSL library that pycurl is expecting. The error will be something like:
pycurl: libcurl link-time ssl backend (<library>) is different from compile-time ssl backend (<library> or "none/other")
To fix it, you have to use the library pycurl is expecting. In my case, my error was "pycurl: libcurl link-time ssl backend (nss) is different from compile-time ssl backend (openssl)", so my fix was:
SSL backend error when using OpenSSL pycurl install error
