在PyCharm中使用Flask-RESTful

Question

我目前正在學習Python（Flask），並希望為HelloWorld設置一個小的REST API。 我選擇flask_restful來實現API並按照他們網站上的教程進行操作。

問題是，PyCharm告訴我ImportError：

沒有名為flask_restful的模塊

雖然我通過我的VirtualEnvironment中的項目解釋器實現了庫。

這是我的代碼：

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__':
    app.run(debug=True)

有沒有人知道這個技巧，正確使用flask_restful？

你需要安裝那個python包，你可以通過以下方式完成：

使用pip安裝Flask-RESTful

pip安裝燒瓶 - 安靜

開發版本可以從GitHub的頁面下載。

git clone https://github.com/flask-restful/flask-restful.git cd flask-restful python setup.py develop

一個好方法是使用virtualenv將python包依賴項從一個項目分離到另一個項目。

我只測試它並且它可以在Ubuntu 16.04上運行： ~/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

從我自己的經驗中得到一個簡短的答案。 您必須先安裝此模塊

sudo pip install flask-restful
