I'm trying to install multiple python versions in linux, but asdf or pyenv get stuck with an error:

ERROR: The Python ssl extension was not compiled. Missing the OpenSSL lib?

apt install libssl or apt install libssl1.0 didn't solved...

I already have version 2.7 and 3.8 by default.

Then I've stalled version 3.4 by downloading its source and building manually. If i try to create a virtual environment like python3.4 -m venv myenv, i can activate python --version shows the correct one:

$ python --version                             
Python 3.4.0

but pip still referenced to python 3.8:

(myenv)$ pip --version                                  
pip 21.0.1 from ~/.local/lib/python3.8/site-packages/pip (python 3.8)

/usr/local/lib/python3.4/site-packages/ only has README file, and i can't figure out how to properly set this

What is the output of `which pip` and `echo $PATH` when your 3.4 virtual env is activated? – Code-Apprentice Apr 09 '21 at 21:21
why not use `python3.4 -m pip --version`...? – Chris_Rands Apr 09 '21 at 21:22
install python as per instructions then in bashrc give alias to each python version you want to use – sahasrara62 Apr 09 '21 at 21:28
i tryied: ```python3.4 -m pip install wheel``` ```/usr/local/bin/python3.4: No module named pip``` – paulogil2010 Apr 09 '21 at 21:28
PIP ```$ which pip``` ```pip: aliased to pip3``` PIP3 ```$ which pip3``` ```/usr/local/bin/pip3``` PATH ```echo $PATH``` ```home/paulo/.asdf/shims:/home/paulo/.asdf/bin:/home/paulo/.nvm/versions/node/v10.19.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin``` – paulogil2010 Apr 09 '21 at 21:30

conda (miniconda) is another option, might be suitable depending on how you want to use Python. – fishstix44 Apr 10 '21 at 03:00
i couldn't figure it out so I updated the project to python3.8 – paulogil2010 Apr 16 '21 at 15:26
Don't you have to install pip first for python 3.4.0? – Green绿色 Nov 02 '21 at 03:13
