Getting Serverless Error spawn python3.8 ENOENT in sls deploy for python requirements

Your local available python (current PATH) version MUST be the same version configured in your serverless.yml provider runtime value.

I had the same problem, but with python 3.9.

In my serverless.yaml file I had the runtime: python3.9 configured.
In my machine, when I ran python3 --version the result was 3.9.5.

After some time trying to understand, I finally saw that if I tried to run python3.9 --version in my machine, it didn't work.

Trying to connect the dots, I imagined that the serverless framework program needed the exact python3.9 bin name.

To solve the problem I downloaded the binaries from the Python Website, installed it and ran serverless deploy again. It worked!!!

To help you with the installation, in case you need (Ubuntu):

$ cd /opt
$ sudo wget https://www.python.org/ftp/python/3.9.13/Python-3.9.13.tgz
$ sudo tar xzf Python-3.9.13.tgz
$ cd Python-3.9.13
$ sudo ./configure --enable-optimizations
$ sudo make altinstall

There are probably other solutions for this problem like using venv or symlinks, but this one helped me first. I hope it helps you too.

For me, when I changed the python version from 3.8 to 3.6 in serverless.yml then only it worked.

I got a similar message on Mac; I ran brew install [email protected], and it worked.

In the file

serverless.yaml, 

setup

runtime: python3.11
