Question

即使路径显示正确，我也无法导入模块。

>>> import cms.middleware.page
Traceback (most recent call last):
  File "<console>", line 1, in <module>
ImportError: No module named middleware.page

Heres显示我的路径没问题

>>> for x in sys.path:
...     if x == "/usr/local/lib/python2.7/site-packages":
...         print x
...
/usr/local/lib/python2.7/site-packages

继承模块

[root@monty codecrab]# ls -l /usr/local/lib/python2.7/site-packages/cms/middleware/page.py
-rw-r--r-- 1 root root 1304 Apr 17 19:49 /usr/local/lib/python2.7/site-packages/cms/middleware/page.py

以下是文件

[root@monty cms]# pwd
/usr/local/lib/python2.7/site-packages/cms
[root@monty cms]# ls -l __init__.py middleware/__init__.py middleware/page.py
-rw-r--r-- 1 root root   47 Apr 17 19:49 __init__.py
-rw-r--r-- 1 root root    0 Apr 17 19:49 middleware/__init__.py
-rw-r--r-- 1 root root 1304 Apr 17 19:49 middleware/page.py

有什么想法吗？

这可能是因为您的包裹安装不正确。

为了能够import cms.middleware.page，cms目录必须位于Python路径上，cms和middleware目录都包含__init__.py个文件这样它们就被视为Python包。

必须存在以下文件/目录：

/usr/local/lib/python2.7/site-packages/cms
/usr/local/lib/python2.7/site-packages/cms/__init__.py
/usr/local/lib/python2.7/site-packages/cms/middleware
/usr/local/lib/python2.7/site-packages/cms/middleware/__init__.py
/usr/local/lib/python2.7/site-packages/cms/middleware/page.py

导入中间件cms.middleware.page时出错：“没有名为middleware.page的模块”
