readthedocs应用程序不会在apache和django上启动

Question

我正在尝试让readthedocs作为apache应用程序运行。我遵循了所有的说明，但我把它归结为我的apache日志中的这个错误。

mod_wsgi (pid=2372): Target WSGI script '/opt/readthedocs.org/readthedocs/wsgi.py' cannot be loaded as Python module.
mod_wsgi (pid=2372): Exception occurred processing WSGI script '/opt/readthedocs.org/readthedocs/wsgi.py'.
Traceback (most recent call last):
  File "/opt/readthedocs.org/readthedocs/wsgi.py", line 8, in <module>
    from django.core.wsgi import get_wsgi_application
  File "/usr/local/lib/python2.7/site-packages/django/__init__.py", line 1, in <module>
    from django.utils.version import get_version

     fasttypes = {int, str, frozenset, type(None)},
                     ^
 SyntaxError: invalid syntax

我不太了解这个系统，不知道我是否应该搜索服务器配置错误，或者我是否正在处理应用程序的这个分支中的错误。

我一直在遵循这些说明，因为这是在专用服务器上进行的，所以我没有使用虚拟环境

Answer 1

当编译 mod_wsgi 时使用的Python版本与正在使用的版本不兼容时，通常会出现此错误。

看起来你使用的是Django 1.8。现在，Django 1.8兼容Python 2.7或更高版本。显然，用于编译mod_wsgi的Python版本低于2.7。

mod_wsgi包针对特定的Python版本进行编译，并通过共享库进行链接。

从mod_wsgi文档中：

在构建mod_wsgi时，应该通过共享库将'mod_wsgi.so'文件与Python链接起来。如果不是这样，并且它被链接到一个静态库上，就会出现各种问题。

你需要做什么？

你需要检查你的mod_wsgi是用哪个Python版本编译的。如果mod_wsgi所链接的Python版本低于2.7，则需要使用Python versions>= 2.7重新编译mod_wsgi。

如何检查mod_wsgi 编译的Python版本？

您可以尝试运行ldd命令并检查输出。

示例输出：

$ ldd mod_wsgi.so
 linux-vdso.so.1 =>  (0x00007fffeb3fe000)
 libpython2.5.so.1.0 => /usr/local/lib/libpython2.5.so.1.0 (0x00002adebf94d000)
 libpthread.so.0 => /lib/libpthread.so.0 (0x00002adebfcba000)
 libdl.so.2 => /lib/libdl.so.2 (0x00002adebfed6000)
 libutil.so.1 => /lib/libutil.so.1 (0x00002adec00da000)
 libc.so.6 => /lib/libc.so.6 (0x00002adec02dd000)
 libm.so.6 => /lib/libm.so.6 (0x00002adec0635000)
 /lib64/ld-linux-x86-64.so.2 (0x0000555555554000)

此外，这是用于检查mod_wsgi安装的official link。
