Run Python3.4 and Python3.7 simultaneously on Linux
I have a linux VM with preconfigured Python3.4. I need to have Python3.7 to run my code.
I tried to uninstall Python3.4 but there are some system dependencies, so I kept old version.
Then I downloaded and installed Python3.7.1.tgz (sudo make).
But now I can't access Python 3.7 instance. When I run a "python3" command, Python 3.4 is run, when "python3.7" then I get a "command not found" message.
How do I proceed? Is it okay to have two versions of Python 3 installed on one machine? What with installation packages by "pip"?

I would not recommend manually fiddling around with source code installations and paths. Use pyenv and save yourself the trouble.
All you have to do is:
- Run the
pyenvinstaller
- Follow the instructions
- Install the Python versions you need
- Choose which Python version you want to use for a given directory, or globally
For example, to install 3.7, check which versions are available:
pyenv install -l | grep 3.7
Then run:
pyenv install 3.7.1
Now, you can choose your Python version:
pyenv global 3.7.1
This switches your python to point to 3.7.1. If you want the system python, run:
pyenv global system
To check which Python versions are available, run pyenv versions.
