【问题描述】：

我在尝试获取我的网站时收到“内部服务器错误”。这是日志文件中的内容：

Tue May  9 02:46:31 2017 - spawned uWSGI worker 3 (pid: 12738, cores: 1)

这是我的 uWSGI 配置文件：

[uwsgi]
project = landingpage
base = /home/ubuntu

chdir = %(base)/%(project)
home = %(base)/%(project)/venv/
module = %(base)/%(project).wsgi:application

logto=/var/log/uwsgi/%(project).log

master = true
processes = 3

socket = /tmp/%(project).sock
chmod-socket = 664
vacuum = true

我真的不知道我在这里错过了什么......

【问题讨论】：

哪个 python 文件抛出了ImportError，它的导入是什么？
这与 uWSGI 无关，而是您的 Python 代码。使用manage.py runserver 运行您的项目并尝试查明错误的位置。

标签： python django nginx uwsgi

【解决方案1】：

错误提示：

ImportError: 不支持按文件名导入。

这导致module = %(base)/%(project).wsgi:application 行，在该行中，您使用 unix 文件路径表示法 (/) 而不是 python (.) 来定位 wsgi 应用程序。

试试module = %(project).wsgi:application

编辑：

另外我遇到了一个问题，我的模块名称不是我项目的目录名称。

我试过了：

module = myrealmodulename.wsgi:application

它成功了！
