燒瓶 - WSGI - 沒有名爲'flask'的模塊

Question

我一直在關注Sentdex'燒瓶教程。他使用Venv來設置他的Flask，但沒有將他的Python設置爲與Venv一起工作。我試過在全球範圍內安裝Flask - 但它仍然無法正常工作。試圖瀏覽到服務器返回一個500內部服務器錯誤

我收到通常的no module named flask錯誤。

Answer 1

1. 根據http://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html。

2. 您應該編輯/etc/apache2/sites-available/FlaskApp.conf

3. 添加這些的WSGIScriptAlias

   WSGIDaemonProcess FlaskApp python-home=/var/www/FlaskApp/FlaskApp/venv/FlaskApp WSGIProcessGroup FlaskApp

上面我遇到了同樣的問題，順便解決它。
