Mod_Wsgi PythonHome不起作用

Question

我犯了个错误，装了一个 Ubuntu Server（12.04）。我安装了 Python3 和对应的 mod_wsgi。

Apache2 启动了，但留下了以下错误日志：

[Mon May 05 11:00:24 2014] [error] python_init: Python version mismatch, expected '2.7.2+', found '2.7.3'.

这是我的 WSGI.conf 文件：

<IfModule mod_wsgi.c>

WSGIPythonHome /usr/bin/python3.2
WSGIPythonPath /home/user/.virtualenvs/my_env/lib/python3.2/site-packages/

</IfModule>

我已经搜索了两个小时，什么都没找到，所以我很想换个服务器操作系统，但重新上传和解析比特币区块链至少要花一天时间。

WSGIPythonHome这个设置不会起作用，因为你同时在Apache中加载了mod_python。在这种情况下，mod_python会覆盖你使用的Python版本。

这个问题在WSGIPythonHome的文档中有提到。

• http://code.google.com/p/modwsgi/wiki/ConfigurationDirectives#WSGIPythonHome

你还可以阅读：

• http://code.google.com/p/modwsgi/wiki/InstallationIssues#Using_ModPython_and_ModWsgi
• http://code.google.com/p/modwsgi/wiki/InstallationIssues#Python_Version_Mismatch
• http://code.google.com/p/modwsgi/wiki/InstallationIssues#Incompatible_ModPython_Versions

另外，WSGIPythonHome本来就不应该设置为Python可执行文件的路径。所以即使你只使用mod_wsgi，这个设置也会被完全忽略。

所以，如果你不需要mod_python，就不要在Apache中加载它。
