pip不起作用，TTPSConnectionPool（host ='pypi.org'，port = 443）：超过了最大重试次数

Question

我尝试这样：

pip install numpy

我得到这个：

The directory '/home/teoman/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

即使问题确实有所不同（我现在注意到了），我几乎已经尝试了该问题的所有内容， 这是怎么回事？
