Visual Studio Code pylint: Unable to import ‘protorpc’

  • 3

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?

enter image description here

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.

enter image description here

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.

      Open the settings file of your Visual Studio Code (settings.json) and add the library path to the "python.autoComplete.extraPaths" list.

      "python.autoComplete.extraPaths": [
    "~/google-cloud-sdk/platform/google_appengine/lib/webapp2-2.5.2",
    "~/google-cloud-sdk/platform/google_appengine",
    "~/google-cloud-sdk/lib",
    "~/google-cloud-sdk/platform/google_appengine/lib/endpoints-1.0",
    "~/google-cloud-sdk/platform/google_appengine/lib/protorpc-1.0"
],
