$ sudo apt-get install build-essential checkinstall Install Required Packages for source compilation If you need to install multiple versions of Python (next to the main one) on a Unix system: # If you want to define the local (project) version: # If you want to define the global version: # Install the Python interpreters that you need: # List all available Python interpreters: If you have asdf installed you can easily download/install new Python interpreters: # Install Python plugin for asdf: Note2: asdf works fine in combination with popular package-managers such as pipenv and poetry. Note1: asdf works not only for Python but for all major languages. These days I suggest using asdf to install various versions of Python interpreters next to each other. The primary version, you would execute "make install" in your 2.6 buildĭirectory and "make altinstall" in the others.

To install multiple versions using the same prefix you must decide which All files andĭirectories installed using "make altinstall" contain the major and minor Overwritten by the installation of a different version.

Link /usr/bin/python to the one you want to use as default.Īll the libraries are in separate folders (named after the version) anyway. usr/bin/python2.5 and /usr/bin/python2.6. Just install them, then you have the commands e.g.
