pip 配置了需要 TLS/SSL 的位置，但是 Python 中的 ssl 模块不可用。

Collecting numpy

Could not fetch URL https://pypi.python.org/simple/numpy/: There was a problem confirming the ssl certificate: 

Can't connect to HTTPS URL because the SSL module is not available. - skipping
  Could not find a version that satisfies the requirement numpy (from versions: )
No matching distribution found for numpy

有人知道怎么解决吗？

Answer 1

解决方案 1:也许尝试使用 sudo -E:

 -E          The -E (preserve environment) option indicates to the secu‐
             rity policy that the user wishes to preserve their existing
             environment variables.  The security policy may return an
             error if the -E option is specified and the user does not
             have permission to preserve the environment.

解决方案 2:代理可能会对此产生影响。所以:

sudo pip --proxy=http://username:password@proxyURL:portNumber install your-package
