[PYTHON] Insecure Platform Warning still appears with pip install, but I didn't do it because it was troublesome.

pip install -> InsecurePlatformWarning

$ python -V
Python 2.7.1
$ pip -V
pip 8.1.1 from /Users/foo/.anyenv/envs/pyenv/versions/2.7.1/lib/python2.7/site-packages (python 2.7)

Why are you angry

https://urllib3.readthedocs.org/en/latest/security.html#snimissingwarning

Certain Python distributions (specifically, versions of Python earlier than 2.7.9) and older OpenSSLs have restrictions that prevent them from using the SNI (Server Name Indication) extension. This can cause unexpected behaviour when making some HTTPS requests, usually causing the server to present the a TLS certificate that is not valid for the website you’re trying to access.

"In versions prior to 2.7.9, you may visit a site with an incorrect certificate."

What happens if the certificate is incorrect

at the worst case,

1. I think it's safe because it's a well-known plugin, so I do pip install (numpy, etc.)
2. The access destination is replaced and the malicious plug-in is downloaded.
3. The certificate is not verified correctly and it is installed.

May be that

pyenv install

trap

I was angry when I tried to pyenv install 2.7.9 normally

ERROR: The Python ssl extension was not compiled. Missing the OpenSSL lib?

Upgrade anyenv

(cd ~/.anyenv && git pull)
exec $SHELL -l
anyenv install pyenv
exec $SHELL -l
pyenv install 2.7.9
pyenv global 2.7.9
pip install secure-and-silent

Congratulations
