Flask 算是新手上路，之前写过小玩意儿，但是基本没有用到 Bluprint 这个 API 基本不是很了解。
报错内容：
Traceback (most recent call last): File "/Users/home/PycharmProjects/Demo/Run.py", line 9, in <module> app = Create_apps() File "/Users/home/PycharmProjects/Demo/apps/__init__.py", line 14, in Create_apps register_blueprints(app) File "/Users/home/PycharmProjects/Demo/apps/__init__.py", line 19, in register_blueprints app.register_blueprint(Admin) File "/Library/python/2.7/site-packages/flask/app.py", line 65, in wrapper_func return f(self, *args, **kwargs) File "/Library/Python/2.7/site-packages/flask/app.py", line 958, in register_blueprint if blueprint.name in self.blueprints: AttributeError: 'function' object has no attribute 'name'从报错种可以看到是 register_blueprints(app) 注册 Bluprint 的时候报错，然后走到下一步就是注册 Admin 这个视图的时候报错了。看到 apps\Admin\Views.py 代码中首先注册了这个视图路由命名为 Admin ，写下一个测试 def Admin(): 的时候因为视图路由本身即是用 Admin 命名，因为定义了一个函数 Admin 产生冲突然后报错。
做一个小测试就知道了！
>>> from flask import Flask >>> app = Flask(__name__) >>> @app.route('/') ... def app(): ... return 'test page!' ... >>> app.run() Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'function' object has no attribute 'run'这样报错的原因就是定义的路由 app 再自定义一个函数 app 导致冲突报错。
下面是正确的代码。
