Pip Issue Installing Almost Any Library

Pip can't confirm SSL certificate

According to Paramiko installation documentation :

Versions supported :

• Python 2.7
• Python 3.4+

Looks like you are using incompatible version of Python

C:\Users\User>python -V
Python 3.6.4

Installation

pip3 install paramiko 

or

pip install paramiko

SSL: CERTIFICATE_VERIFY_FAILED can be caused by pip issue or python issue on Mac

Please upgrade pip to latest version for the same.

pip install --upgrade pip

After this issue should be resolved

Or try installing incremental

pip install incremental

pip install' fails for every package (Could not find a version that satisfies the requirement)

Upgrade pip as follows:

curl https://bootstrap.pypa.io/get-pip.py | python

Note: You may need to use sudo python above if not in a virtual environment.

What's happening:

Python.org sites are stopping support for TLS versions 1.0 and 1.1. This means that Mac OS X version 10.12 (Sierra) or older will not be able to use pip unless they upgrade pip as above.

(Note that upgrading pip via pip install --upgrade pip will also not upgrade it correctly. It is a chicken-and-egg issue)

This thread explains it (thanks to this Twitter post):

Mac users who use pip and PyPI:

If you are running macOS/OS X version 10.12 or older, then you ought
to upgrade to the latest pip (9.0.3) to connect to the Python Package
Index securely:

curl https://bootstrap.pypa.io/get-pip.py | python

and we recommend you do that by April 8th.

Pip 9.0.3 supports TLSv1.2 when running under system Python on macOS <
10.13. Official release notes: https://pip.pypa.io/en/stable/news/

Also, the Python status page:

Completed - The rolling brownouts are finished, and TLSv1.0 and TLSv1.1 have been disabled. Apr 11, 15:37 UTC

Update - The rolling brownouts have been upgraded to a blackout, TLSv1.0 and TLSv1.1 will be rejected with a HTTP 403 at all times.
Apr 8, 15:49 UTC

Lastly, to avoid other install errors, make sure you also upgrade setuptools after doing the above:

pip install --upgrade setuptools

Cannot use pip to install packages, it reports an error on ssl certificate

As I answered here https://stackoverflow.com/a/49798838/9586409.

You have to upgrade pip to a version with a TLSv1.2 support. You can do it by running this command:

curl https://bootstrap.pypa.io/get-pip.py | python

upgrading pip and installing library are giving same error again and again

Do the PIP install in an administrative command prompt.
It seems your command prompt does not have required priviledges.

Just press win key and type cmd, and select the command prompt and right click on it

From the menu, select Run as Administrator
