python3.6 ssl erro

Question

In Ubuntu 16.04, I use python3.6 ( pip 9.0.1) to install BeautifulSoup but failed. The error is:

pip is configured with locations that require TLS/SSL , however the ssl module in Python is not available. 
could not fetch URL https://pypi.python.org

Secondly, Ubuntu 16.04 ships with the built-in python2.7, but I want to learn Python 3.6. So I load it and use that order:

./configure
make && make install

The result is the python 3.5 was installed in the PATH , and BeautifulSoup was installed. I use make altinstall to complete the Python 3.6 installing. It's so wondering.

Answer 1

Before ./configure you need install all requirements.

In your case, not enough libssl-dev library.

To install it using apt do this:

# apt install libssl-dev
