Python和IntelliJ出现问题

Question

I'm writing a Flask application in IntelliJ, and for some reason I can't get IntelliJ to recognize Flask extensions. And so this works just fine:

from flask import Flask, Response, request

But this does not:

from flask.ext.wtf import Form

It will recognize and autocomplete flask.ext but not any submodules.

Does anyone know what the problem could be?

More info:

• I'm using virtualenv and installing dependencies via bin/pip install <dependency> .
• I'm using the Python 2.7.5 SDK
• The modules that I'm trying to get IntelliJ to recognize have all been successfully installed.

Answer 1

PyCharm has difficulty completing flask.ext... because all flask.ext does is proxy imports at runtime, so the built-in static detection is faulty.

For future reference, flask.ext is deprecated in favor of using the actual package import such as from flask_wtf import Form . As of Flask 1.0 it has been removed completely.
