Python path issue with Visual studio code

Question

I am experiencing an issue with AWS Lamda (python 3.8) while trying to debug it locally. AWS SAM Cli commands are working fine while executing from terminal. However, while trying to debug or build from vscode it throws an error. Seems like vscode is picking a different path for python 3.8 version.

Here is the configuration path snapshot from terminal:

mbp$ which python
/usr/bin/python
mbp$ which python3
/usr/local/opt/python@3.8/bin/python3
mbp$ which aws
/usr/local/bin/aws
mbp$ which sam
/usr/local/bin/sam
mbp$ python --version
Python 2.7.16
mbp$ python3 --version
Python 3.8.8

Here is the visual-studio-code log:

Answer 1

Another solution that you can try is create a .vscode folder in your project directory and then create a settings.json file inside that directory. Inside the file create

{
    "python.pythonPath": "<python path>",
}

replace the python path with the path to your python binary file.

Answer 2

It worked once after setting the python path /usr/local/opt/python@3.8/bin/python3 in vscode View > command palette > Python: select interpreter
