Visual Studio Code pylint Unable to import protorpc

Question

I m using pylint in Visual Studio Code to develop a Google App Engine  GAE  Cloud Endpoint API in Python  I m unable to resolve a lint error  I don t know what s causing the error  but at a guess  pylint cannot find the protorpc library     The recommended fix in Troubleshooting Linting is to configure workspace settings to point to fully qualified python executable  I have done this  but the lint error remains     protorpc itself is installed to      google-cloud-sdk platform google appengine lib protorpc-1 0 protorpc      and this contains the remote py module that cannot be imported     init   py             generate python py      protojson py            transport py definition py           google imports py       protourlencode py       util py descriptor py           message types py        registry py             webapp generate py             messages py             remote py               wsgi generate proto py       protobuf py             static   I ve added this path to  PYTHONPATH  along with the kitchen sink    export GOOGLE CLOUD SDK   google-cloud-sdk export APPENGINE PATH  GOOGLE CLOUD SDK platform google appengine  export PYTHONPATH  PYTHONPATH  GOOGLE CLOUD SDK export PYTHONPATH  PYTHONPATH  GOOGLE CLOUD SDK lib export PYTHONPATH  PYTHONPATH  GOOGLE CLOUD SDK lib googlecloudsdk export PYTHONPATH  PYTHONPATH  GOOGLE CLOUD SDK lib googlecloudsdk api lib export PYTHONPATH  PYTHONPATH  GOOGLE CLOUD SDK platform google appengine lib export PYTHONPATH  PYTHONPATH  GOOGLE CLOUD SDK platform google appengine lib protorpc-1 0 protorpc   The application runs locally and also when deployed  so this appears to be just a lint error  but it s frustrating that I can t solve it   Using third-party libraries states      The Python runtime in the standard environment includes the Python   standard library  the App Engine libraries  and a few bundled   third-party packages    Because of this  I assumed  the App Engine libraries  includes protorpc  but I m unsure   Moreover  Adding the Cloud Endpoints Frameworks library to the sample API only requires google-endpoints be installed to the app s lib directory   pip install -t lib google-endpoints --extra-index-url https   gapi-pypi appspot com admin nurpc-dev --ignore-installed   My point is  I don t think I ve not installed something  and I don t think I m missing anything in my  web  app s lib directory

I was still getting these errors even after confirming that the correct python and pylint were being used from my virtual env.

Eventually I figured out that in Visual Studio Code I was A) opening my project directory, which is B) where my Python virtual environment was, but I was C) running my main Python program from two levels deeper. Those three things need to be in sync for everything to work.

Here's what I would recommend:

In Visual Studio Code, open the directory containing your main Python program. (This may or may not be the top level of the project directory.)
Select Terminal menu > New Terminal, and create an virtual environment directly inside the same directory.
```
python3 -m venv env
```
Install pylint in the virtual environment. If you select any Python file in the sidebar, Visual Studio Code will offer to do this for you. Alternatively, source env/bin/activate then pip install pylint.
In the blue bottom bar of the editor window, choose the Python interpreter env/bin/python. Alternatively, go to Settings and set "Python: Python Path." This sets python.pythonPath in Settings.json.

I resolved this by adding the protorpc library to the  PYTHONPATH environment variable  Specifically  I pointed to the library installed in my App Engine directory   export PYTHONPATH  PYTHONPATH  Users jackwootton google-cloud-sdk platform google appengine lib protorpc-1 0   After adding this to    bash profile  restarting my machine and Visual Studio Code  the import errors went away   For completeness  I did not modify any Visual Studio Code settings relating to Python  Full    bash profile file   export PATH  Users jackwootton protoc3 bin  PATH  export PYTHONPATH  Users jackwootton google-cloud-sdk platform google appengine  export PYTHONPATH  PYTHONPATH  Users jackwootton google-cloud-sdk platform google appengine lib protorpc-1 0    The next line updates PATH for the Google Cloud SDK  if   -f   Users jackwootton google-cloud-sdk path bash inc     then source   Users jackwootton google-cloud-sdk path bash inc   fi    The next line enables shell command completion for gcloud  if   -f   Users jackwootton google-cloud-sdk completion bash inc     then source   Users jackwootton google-cloud-sdk completion bash inc   fi

I got the same error on my vscode where I had a library installed and the code working when running from the terminal  but for some reason  the vscode pylint was not able to pick the installed package returning the infamous error      Unable to import  someLibrary someModule  pylint import-error    The problem might arise due to the multiple Python installations  Basically you have installed a library package on one  and vscode pylint is installed and running from another installation  For example  on macOS and many Linux distros  there are by default Python2 installed and when you install Python3 this might cause confusion  Also on windows the Chocolatey package manager might cause some mess and you end up with multiple Python installations  To figure it out if you are on a  nix machine  i e   macOS  GNU Linux  BSD      use the which command  and if you are on Windows  use the where command to find the installed Python interpreters  For example  on  nix machines   which python3   and on Windows  where python   then you may want to uninstall the ones you don t want  and the one you want to use check if the package causing above issue is installed by  python -c  import someLibrary    if you get an error then you should install it by for example pip   pip install someLibrary   then on vscode press   P if you are on a mac and CtrlShiftP on other operating systems  Then type-select the  gt python  Select Interpreter option and select the one you know have the library installed  At this moment vscode might asks you to install pyling again  which you just go on with

For your case  add the following code to vscode s settings json    python linting pylintArgs          --init-hook  import sys  sys path append     google-cloud-sdk platform google appengine lib          For the other who got troubles with pip packages  you can go with   python linting pylintArgs          --init-hook  import sys  sys path append    usr local lib python3 7 dist-packages          You should replace python3 7 above with your python version

Spent hours trying to fix the error for importing local modules  Code execution was fine but pylint showed      Unable to import   lt module gt    Finally figured   First of all  select the correct python path   In the case of a virtual environment  it will be venv bin python   You can do this by hitting  Make sure that your pylint path is the same as the python path you chose in step 1   You can open VS Code from within the activated venv from terminal so it automatically performs these two steps   The most important step  Add an empty   init   py file in the folder that contains your module file  Although python3 does not require this file for importing modules  I think pylint still requires it for linting    Restart VS Code  the errors should be gone

I ve not played around with all possibilities  but at least I had the impression that this could be a python version related issue  No idea why  I just trusted my gut   Thus I just changed the pythonPath to python3  default  python     python pythonPath    python3    I reinstalled the dependencies  including pylint     with  pip3 install  lt package gt  --user       and after restarting vs code  everything looked fine   HTH Kai

Changing the library path worked for me  Hitting Ctrl   Shift   P and typing python interpreter and choosing one of the available shown  One was familiar  as pointed to a virtualenv that was working fine earlier  and it worked  Take note of the version of python you are working with  either 2 7 or 3 x and choose accordingly

First I will check the python3 path where it lives     And then in the VS Code settings just add that path  for example    python pythonPath     usr local bin python3

I find the solutions stated above very useful  Especially the Python s Virtual Environment explanation by jrc   In my case  I was using Docker and was editing  local  files  not direcly inside the docker   So I installed Remote Development extension by Microsoft   ext install ms-vscode-remote vscode-remote-extensionpack  More details can be found at https   marketplace visualstudio com items itemName ms-vscode-remote vscode-remote-extensionpack  I should say  it was not easy to play around at first  What worked for me was    1  starting docker 2  In vscode  Remote-container  Attach to running container 3  Adding folder  code  lt path-to-code-folder gt  from root of the machine to vscode   and then installing python extension   pylint
