python - 服务器上的 django 应用程序 : apache runs with python 2. 7 而不是 python 3.5

Question

我的 ubuntu 服务器上有一个 Django 应用程序。到目前为止，我使用的是 python 2.7。

我的 Django 版本是 1.11.6。

从现在开始，我想使用 python 3.5。但是当我运行 sudo service apache2 restart我收到包含 python 2.7 的错误:

你知道如何解决这个问题吗？

Answer 1

也许你安装了用于 python 2 的 libapache2-mod-wsgi 包。

对于 python 3，您需要安装 libapache2-mod-wsgi-py3，然后 apache 将使用 python3。
