Flask-WSGI-没有名为“ flask”的模块

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。我已经尝试过在全球范围内安装Flask-但仍然无法正常工作。尝试浏览到服务器将返回500 Internal Server Error

我遇到了通常的no module named flask错误。

回答：

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

  2. 在“ WSGIScriptAlias”行之前添加以下两行：

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

  1. 通过“ service apache2 restart”重启Apache

    我当然用Python3.5代替了Python版本，这就是我正在运行的版本。
