[英]Using Flask-RESTful in PyCharm
我目前正在学习Python(Flask),并希望为HelloWorld设置一个小的REST API。 我选择flask_restful来实现API并按照他们网站上的教程进行操作。
问题是,PyCharm告诉我ImportError:
没有名为flask_restful的模块
虽然我通过我的VirtualEnvironment中的项目解释器实现了库。
这是我的代码:
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)
有没有人知道这个技巧,正确使用flask_restful?

你需要安装那个python包,你可以通过以下方式完成:
使用pip安装Flask-RESTful
pip安装烧瓶 - 安静
开发版本可以从GitHub的页面下载。
git clone https://github.com/flask-restful/flask-restful.git cd flask-restful python setup.py develop
一个好方法是使用virtualenv将python包依赖项从一个项目分离到另一个项目。
我只测试它并且它可以在Ubuntu 16.04上运行: ~/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

从我自己的经验中得到一个简短的答案。 您必须先安装此模块
sudo pip install flask-restful
