Install flask with pycharm and app engine
提问by NGix
I'm using pycharm (4.0.1) on windows, I created a new app engine project, tested, project ran.
我在 Windows 上使用 pycharm (4.0.1)，我创建了一个新的应用引擎项目，经过测试，项目运行。
In project settings I added a virtual environment where I installed flask. Everything seems to be fine, interpreter points to my virtual environment and when I start typing in pycharm from flask import Flaskit autocompletes import.
在项目设置中，我添加了一个安装 Flask 的虚拟环境。一切似乎都很好，解释器指向我的虚拟环境，当我开始输入 pycharm 时，from flask import Flask它会自动完成导入。
When I run project it's buildt with no errors. But when I access a page in a browser I get the following error:
当我运行项目时，它的构建没有错误。但是当我在浏览器中访问页面时，出现以下错误：
File "C:\GAP\myproject\main.py", line 1, in <module>
from flask import Flask
ImportError: No module named flask
Does anyone know what's the problem?
有谁知道是什么问题？

Windows Pycharm, you can go to File->Settings->Project interpreter, click the green +button (Install), type in flask, select Flaskfrom the list then click Install Package. After installation, you will get the message saying flask installed successfully. You can rerun the project.

have you ran
你跑了吗
pip install flask
also to use flask with google app engine on production environment , you will have to place the flask folder within your project (e.g in a lib/folder) and add it to the system path in the appengine_config.pylike this:
还要在生产环境中使用带有谷歌应用引擎的烧瓶，您必须将烧瓶文件夹放在您的项目中（例如在lib/文件夹中）并将其添加到系统路径中，appengine_config.py如下所示：
sys.path.insert(0, os.path.join(os.path.dirname(__file__), 'lib'))
sys.path.insert(0, os.path.join(os.path.dirname(__file__), 'lib'))
