flask解决WARNING: This is a development server. Do not use it in a production deployment.

解决 pycharm flask项目无法正常运行

报错如下：WARNING: This is a development server. Do not use it in a production deployment.

解决方法：更改启动服务器使用WSGI.

我的python版本为python 3.7所以只能使用gevent包来启用WSGI

下载gevent包:在控制台输入：

pip install gevent

之后在代码中导入个gevent后调用，再run app就ok了

from gevent import pywsgiif __name__ == '__main__':server = pywsgi.WSGIServer(('0.0.0.0', 5000), app)server.serve_forever()

但在使用pip下载gevent时出现问题，在我将gevent包下载完成后，仍无法在项目中调用gevent包。解决方案是直接在编译器内导入gevent包

直接点加号，输入gevent 下载即可（pip版本不够，无法下载，可以先更新下pip版本）

其他包下载也可以使用这个方法，比控制台简单好用。
