Python Question

Using Flask-RESTful in PyCharm

I'm currently learning Python (Flask) and would like to setup a tiny REST API for an HelloWorld. I choose flask_restful to implement the API and followed the tutorial on their website.

The problem is, that PyCharm is telling me the ImportError:

No module named flask_restful

although I implemented the library via the project interpreter in my VirtualEnvironment.

This is my code:

from flask import Flask
from flask_restful import Resource, Api

app = Flask(__name__)
api = Api(app)

class HelloWorld(Resource):
def get(self):
return {'hello': 'world'}

api.add_resource(HelloWorld, '/')

if __name__ == '__main__':

Does anybody know the trick, to use flask_restful correctly?

Answer Source

you need to install that python package, you can do it by:

Install Flask-RESTful with pip

pip install flask-restful

The development version can be downloaded from its page at GitHub.

git clone cd flask-restful python develop

A good way is to also use virtualenv to separate python package dependencies from one to an other project.

I just test it and it work on Ubuntu 16.04: ~/repositories$ virtualenv venv_flask_restful New python executable in venv_flask_restful/bin/python2.7 Also creating executable in venv_flask_restful/bin/python Installing setuptools, pip, wheel...done. ~/repositories$ source venv_flask_restful/bin/activate
(flask_restful) ~/repositories$ pip install flask-restful
... ~/repositories$ pip freeze aniso8601==1.2.0 ...
