I installed python3.7 from here https://tecadmin.net/install-python-3-6-on-centos/ When trying to use/upgrade/install pip I got the following error:

[cloudera@quickstart Python-3.7.6rc1]$ sudo pip3 install --upgrade
WARNING: pip is configured with locations that require TLS/SSL,
however the ssl module in Python is not available.
ERROR: You must give at least one requirement to install (see "pip

port=443): Max retries exceeded with url: /simple/pip/ (Caused by
SSLError("Can't connect to HTTPS URL because the SSL module is not
available.")) - skipping

Version information

[cloudera@quickstart Python-3.7.6rc1]$ pip3 --version
pip 19.2.3 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)
[cloudera@quickstart Python-3.7.6rc1]$ whereis pip3

/usr/local/bin/openssl /usr/include/openssl
/usr/share/man/man1/openssl.1ssl.gz

I tried several commands suggested here for this error but nothing helped. Can you help me?

Follow this Steps:

pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org PACKAGE_NAME

Example --> pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org matplotlib

Hope this helps :)

You are probably missing some basic requirements for python. Try installing all of them with sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev

  • libssl-dev is the one missing probably – D.T. Oct 17 '20 at 16:39
  • I tried that but No package all of them Error: Nothing to do. How can I install them? – gigives Oct 17 '20 at 16:47
  • @gigives, You've already installed pip3. In the command `sudo pip3 install --upgrade` you are missing the argument (requirement to install). If you just want to upgrade pip itself, you need to do `pip3 install --upgrade pip` (you could run it with sudo, [but it's not generally a good practice](https://stackoverflow.com/a/37104948/2033046) ). – kenichi Oct 17 '20 at 19:38
  • hello @kenichi, and then I become the same error. Please look at my updated question. – gigives Oct 17 '20 at 23:35

I fixed this by starting pip while in the directory where the executable resides. Permanent fix was to add the required bin & scripts directories to Path.

Don't forget to restart docker and ensure you have connectivity to the internet.

Solution:

After going through everywhere, I ended up uninstalling python and vs code. Deleted all the vs code, python, and pip cache files saved under %AppData%. Reinstalled python and vs code.

Success.

pip is 19.0.3 and I am keeping it this way because I think the problem started when I updated it to 20.3.3. Once you update to 20.3.3, you're not going to be able to downgrade it because of the SSL error.

Please try the install command by adding the trusted hosts to pip as follows as answered here

sudo pip3 install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org -upgrade pip

I like this write up on the explanation of the problem and other solutions.
