Flask-WSGI-没有名为"flask"的模块

问题描述

我一直在关注Sentdex的Flask教程.他使用Venv来设置他的Flask，但是没有设置Python与Venv一起使用.我曾尝试在全球范围内安装Flask-但仍然无法正常工作.尝试浏览到服务器会返回500 Internal Server Error

I've been following Sentdex' Flask tutorial. He's using a Venv to set up his Flask, but didn't set his Python up to work with a Venv. I've tried installing Flask globally - yet it still doesn't work. Trying to browse to the server returns a 500 Internal Server Error

我遇到了常见的no module named flask错误.

推荐答案

就像在查找解决方案时的礼貌举止一样，我在Google上搜索了更多内容，并设法从Nathan Nichols的YouTube评论中找到了解决方案:

As is polite behaviour when finding the solution, I googled around a bit more, and somehow managed to find a solution from a YouTube commment by Nathan Nichols here:

1. 编辑/etc/apache2/sites-available/FlaskApp.conf

2. 在"WSGIScriptAlias"行之前添加以下两行:

1. Edit /etc/apache2/sites-available/FlaskApp.conf

2. Add the following two lines before the "WSGIScriptAlias" line:

WSGIDaemonProcess FlaskApp python-path=/var/www/FlaskApp:/var/www/FlaskApp/FlaskApp/venv/lib/python2.7/site-packages
WSGIProcessGroup FlaskApp

通过"service apache2 restart"重新启动Apache

我当然用我正在运行的python3.5替换了Python版本.

I of course replaced the Python version with python3.5, which is what I'm running.
