Apache使用的源代码与python使用的源代码相同，它们都是相同的版本。看起来Python使用的是64位，而Apache不是？也许我是在白费力气。我能解决这个问题。我不确定这是否是“正确”的方式，但它对我来说很有效。由于我注意到我的apache lib dir中的libexpat.so.0符号链接指向/usr/local/lib中的符号链接，并且该符号链接实际上不包含错误所抱怨的字符串，因此我删除了该符号链接，并创建了一个指向/lib64/libexpat.so.1.5.2的新符号链接，如下所示：
sudo ln -s /lib64/libexpat.so.1.5.2 libexpat.so.0
我想我会为自己发布解决方法，以防其他人遇到这个奇怪的错误。在您插入上面的代码片段之后，只需在python控制台中打印：>>>
pyexpatsudo ln -s /lib64/libexpat.so.1.5.2 libexpat.so.0
