读取INSTALLATION文件后，我的问题通过设置环境变量并重新安装

• 删除现有 pycurl 安装

  
  
  

  pip uninstall pycurl



• p>导出变量与您的链接时间ssl后端（以上是openssl）
  
  

  export PYCURL_SSL_LIBRARY = openssl




• 然后重新安装 pycurl

  
  
  

  pip install pycurl

但是这对我在 virtualenv 和 pip 安装完美。

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 compile-time ssl backend (none/other)

I read some documentation saying that "To fix this, you need to tell setup.py what SSL backend is used" (source) although I am not sure how to do this since I installed pycurl using pip.

How can I specify the SSL backend when installing pycurl with pip?

Thanks

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

  pip install pycurl

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