Error SSL with python (https)

Question

I am under debian 8

I'd tried to instal : python-telegram-bot (https://github.com/python-telegram-bot/python-telegram-bot) but when I did "python setup.py install" it make an error :

Installed /usr/local/lib/python2.7/site-packages/python_telegram_bot-5.3.1-py2.7.egg
Processing dependencies for python-telegram-bot==5.3.1 Searching for certifi 
Reading https://pypi.python.org/simple/certifi/
Download error on https://pypi.python.org/simple/certifi/: unknown url type: https -- Some packages may not be found!

So I have tried to re-install python 2.7.13 with open-ssl:

apt-get install opensll
apt-get install libssl-dev

I edited the /Modules/setup.dist :

# Socket module helper for socket(2)
_socket socketmodule.c timemodule.c

# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable: SSL=/usr/local/ssl
_ssl _ssl.c \
        -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
        -L$(SSL)/lib -lssl -lcrypto

After that, I ran ./configure and make && make install

I have the error :during install :

Makefile:1081: recipe for target 'libinstall' failed make: *** [libinstall] 
Error 1

And python-telegram-bot would'n compile ...

Can someone have a idea ?

Thanks you very much. Regards

Answer 1

I would recommend trying to reinstall python2.7 after installing OpenSSL, as was suggested in the following stackoverflow answer:

https://stackoverflow.com/a/19926770/3826254

Or simply use pip to install the python package instead.

Answer 2

I got exactly the same error when I was trying to install python2.7.13 from source.

I tried a lot of things and after spending a lot of time got to know that one of the library libreadline6-dev was missing.

So installed it:

sudo apt-get install libreadline6-dev

and it worked fine for me.

Here are the commands which I used to compile and make install (inside Python-2.7.13 directory:

./configure --prefix /usr/bin/python2.7.13
sudo make altinstall
