Python version specified in environment variables isn't installed

1

I’m trying to deploy a python web service with python 3.8.9 by setting the PYTHON_VERSION environment variable to be 3.8.9, as per the documentation . However, I can not find any trace of python 3.8.9 on the VM when I shell into it.

ls -ls /usr/bin/python* and ls -ls /usr/local/bin/python* both show only show 3.7:

render@shell:~/project/src$ ls -ls /usr/local/bin/python*
 0 lrwxrwxrwx 1 root root     7 Jun 23  2021 /usr/local/bin/python -> python3
 0 lrwxrwxrwx 1 root root    14 Jun 23  2021 /usr/local/bin/python-config -> python3-config
 0 lrwxrwxrwx 1 root root     9 Jun 23  2021 /usr/local/bin/python3 -> python3.7
 0 lrwxrwxrwx 1 root root    16 Jun 23  2021 /usr/local/bin/python3-config -> python3.7-config
36 -rwxr-xr-x 2 root root 36864 Jun 23  2021 /usr/local/bin/python3.7
 0 lrwxrwxrwx 1 root root    17 Jun 23  2021 /usr/local/bin/python3.7-config -> python3.7m-config
36 -rwxr-xr-x 2 root root 36864 Jun 23  2021 /usr/local/bin/python3.7m
 4 -rwxr-xr-x 1 root root  2894 Jun 23  2021 /usr/local/bin/python3.7m-config

Additionally, poetry can not find python 3.8 either:

render@shell:~/project/src$ poetry env use 3.8
/bin/sh: 1: python3.8: not found

I’m not sure how to debug further. Am I missing something?

Hi Devon,

Could you take a look at the top of your deploy logs? That should print the version being used.

Thanks for the reply!

It does say it’s using Python 3.8.9

Feb 17 02:29:27 PM  ==> Cloning from https://github.com/lever-ai/easel-api...

Feb 17 02:29:57 PM  ==> Running build command '. ./scripts/build.sh'...

However, if I shell on the box, there’s no trace of any python versions outside of 3.7. Does creating the shell (through the console) connect to a different environment? Are the specified python versions installed elsewhere (I’ve only checked /usr/bin and /usr/local/bin)?

Hi Devon,

When you SSH into the box you can checkout the python version being used with

python --version

And you can see where this is installed with

which python

Let me know if that yields the expected results.

Regards,

Matt
