python - 部署 Django 应用程序时出现问题

Question

当我尝试访问 django 网站时出现“内部服务器错误”。我正在使用 Django 1.8、Python 2.7.10、centos 6.5 和 apache。

在 apache 日志中，我收到以下错误:

mod_wsgi (pid=23866): Target WSGI script '/abc/abc/abc/wsgi.py' cannot be loaded as Python module.
[Mon May 25 14:40:47 2015] [error] [client xyz] mod_wsgi (pid=23866): Exception occurred processing WSGI script '/abc/abc/abc/wsgi.py'.

虽然您说您运行的是 Python 2.7，但此错误表明您实际上使用的是 2.6，因为集合文字仅在 2.7 中引入。

问题是 mod_wsgi 是针对特定的 Python 版本编译的，在您的情况下是 Centos 6.5 附带的版本。您将需要为 2.7 重新编译它，或者找到一个已经针对它编译的版本。
