django导入错误-没有core.management模块

我看到很多这样的错误。我已经尝试了所有我知道的方法，但还是没有找到答案。

我正在一个运行python 2.5和Django 1.3的开发服务器上工作。Django 1.3是在解压tar.gz下载文件后使用python setup.py install安装的。

一切都很好，我很少需要运行manage.py，但我试图使用新的staticfiles应用程序，我遇到了问题。

python manage.py collectstatic
Traceback (most recent call last):
  File "manage.py", line 2, in <module>
    from django.core.management import execute_manager
ImportError: No module named core.management

好的，我有PATH问题。

在Django安装中，我仔细检查了我的site-packages目录。

python -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"
/usr/lib/python2.5/site-packages

让我们看看我有什么，echo $PYTHON_PATH是空的，所以我设置了它

export PYTHON_PATH=/usr/lib/python2.5/site-packages/django

还是不走运。让我们来看看sys。路径会说

>>> import sys
>>> print sys.path
['', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload', '/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages/PIL', '/usr/lib/python2.5/site-packages/django', '/var/lib/python-support/python2.5']

路径在那里，我甚至创建了/usr/lib/python2.5/site-packages/django.pth

cat /usr/lib/python2.5/site-packages/django.pth 
/usr/lib/python2.5/site-packages/django/

有人知道这里发生了什么吗?

我发现了一个符号链接进一步的路径，这是在路上，但没有一个新的错误。

python manage.py collectstatic
Traceback (most recent call last):
  File "manage.py", line 14, in <module>
    execute_manager(settings)
  File "/usr/lib/python2.5/site-packages/django/core/management/__init__.py", line 438, in execute_manager
    utility.execute()
  File "/usr/lib/python2.5/site-packages/django/core/management/__init__.py", line 349, in execute
    version=get_version(),
  File "/usr/lib/python2.5/site-packages/django/__init__.py", line 12, in get_version
    from django.utils.version import get_svn_revision
ImportError: No module named utils.version

我还尝试创建一个新项目，看看是否有任何问题，并获得相同的utils。版本错误。

Side node:来自#django的unnode帮了我一点忙，在同一台机器上设置了virtualenv，并解决了错误，所以仍然不确定这里的实际安装是什么，但它似乎不在django项目中，而是在django/python安装中。

当前回答

你们所有人都没有提到像我这样的人会在安装virtualenv之前先安装django……所以对于我的同类，如果你那样做了…激活virtualenv后重新安装django ..我希望这对你有所帮助

其他回答

只是一个错误这种情况也发生在我身上。我的错误是在创建虚拟env之前创建了Django项目，后来激活了env并试图启动服务器。激活env后安装Django就可以了

如果你像我一样，在virtualenv中运行django，并得到这个错误，请查看你的manage.py。第一行应该定义用于运行脚本的python可执行文件。这应该是你的virtualenv的python的路径，但它是错误的，如/usr/bin/python，这不是相同的路径，将使用全局python环境(包将丢失)。只需将路径更改为virtualenv中python可执行文件的路径。

你也可以用#!/usr/bin/env python。这应该使用适当的python环境和解释器，前提是您首先激活了virtualenv(我假设您知道如何做到这一点)。

对于那些使用Django 1.6或更新版本的人，请注意execute_manager已被删除。在第二个SO答案中有一个答案。

================================== 解决方案 =========================================

第一个转到：虚拟环境

通过运行命令: 源bin /激活

然后安装django，因为你会得到与import django相关的错误:

pip install django

然后运行:

python manage.py runserver

(注意:请将'runserver'更改为您要运行的程序名称)

对于同样的问题，它在我的案例中起了作用。 ================================== 剧情简介 =========================================
