Issues with detection of Python on codespaces

[DonJayamanne]

Test environment

Create a codespace from https://github.com/github/codespaces-jupyter

Problem 1: Two instead of 1

The following two envs are the same, curren is a symlink to 3.10.13

Problem 2 : Incorrect sys.prefix

The exes /usr/local/python/current/bin/python and /usr/local/python/current/bin/python3 are symlinks to the same exe /usr/local/python/3.10.13/bin/python3.10 However they produce different sys.prefix values.

Problem 3: We are spawning

Solution for Problem 2

• Find the real file of the exe (e.g. /usr/local/python/current/bin/python or /usr/local/python/current/bin/python3)
• If the file is still in the same directory, then we know what the real exe is, in this case it is /usr/local/python/current/bin/python3.10
• Use this real exe to run Python and get the version and sys prefix information
