Pip can't confirm SSL certificate

I am having trouble installing paramiko on one system. This same command worked earlier, but then something changed and I had reinstall Python, and now paramiko will not install. I am using Windows 7 with Python 3.6.4. Pip returns the following error:

C:\Users\me>pip --trusted-host pypi.python.org install paramiko
Collecting paramiko
  Could not fetch URL https://pypi.python.org/simple/paramiko/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777) - skipping
  Could not find a version that satisfies the requirement paramiko (from versions: )
No matching distribution found for paramiko

How can I fix this?

Solution

  • 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
