“SSL module in Python is not available” when insta

Question

I've install Python 3.4 and Python 3.6 on my local machine successfully, but am unable to install packages with pip3.

When I execute pip3 install <package>, I get the following SSL related error:

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting <package>
  Could not fetch URL https://pypi.python.org/simple/<package>/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping
  Could not find a version that satisfies the requirement <package> (from versions: )
No matching distribution found for <package>

How can I fix my Python3.x install so that I can install packages with pip install <package>?

Answer 1

The problem probably caused by library missing.

Before you install python 3.6, make sure you install all the libraries required for python.

$ sudo apt-get install build-essential checkinstall 
$ sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev

Answer 2

I was having the same problem for the last two days and only have fixed it right now.

I had tried to use --trust-host option with the DigiCert_High_Assurance_EV_Root_CA.pem did not work, I couldn't install the ssl module (It tells it cannot be installed for python versions greater than 2.6), setting the $PIP_CERT variable didn't fix it either and I had libssl1.0.2 and libssl1.0.0 installed. Also worth mentioning I didn't had a ~/.pip/pip.conf file, and creating it didn't solve the bug either.

What finally solved it, was installing python3.6 with make again. Download the Python-3.6.0.tgz from the website, run configure then make, make test and make install. Hope it works for you.

Agree with the answer by mastaBlasta. Worked for me. I encountered the same problem as the topic description.

Environment: MacOS Sierra. And I use Homebrew.

My solution:

1. Reinstall openssl by brew uninstall openssl, brew install openssl;

2. According to the hints given by Homebrew, do the following:

   echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

   export LDFLAGS="-L/usr/local/opt/openssl/lib"

   export CPPFLAGS="-I/usr/local/opt/openssl/include"
