pip does not work, TTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded

Question

I try this:

pip install numpy

I get this:

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.
The directory '/home/teoman/.cache/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

I've almost tried everything from this question even though the problem is actaully different (I noticed it now) What is wrong?

The easiest way is to download the .whl files manually from Pypi and install them directly. You don't need SSL for that — c2huc2hu, Jun 13 '18 at 13:12
That's may be right but I do not want to install packages via wheels forever, I need to solve this. — teoman, Jun 14 '18 at 05:45
As a guess, try installing the ssl package manually. Then try `pip install numpy` — c2huc2hu, Jun 14 '18 at 13:11

You can use a mirror:

pip install --index https://pypi.mirrors.ustc.edu.cn/simple numpy

The --index argument enables specifying the python lib mirror.

For China region user, here are some mirrors: 找到了一些国内镜像如下：
