OpenShift Django项目部署失败：“错误：无法在安装目录中创建或删除文件”

长时间不活动后，我正在更新项目，但出现了问题。部署失败，并且在之后应用程序未重新启动git push。

我仍然可以通过运行手动启动我的应用程序gear start，但是要成功安装程序包所需的部署步骤将install_requires失败。

以下是部分gear deploy输出：

Activating virtenv
Running setup.py script..
running develop
error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 13] Permission denied: '/usr/lib/python2.6/site-packages/test-easy-install-358943.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /usr/lib/python2.6/site-packages/

Perhaps your account does not have write access to this directory?  If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

  http://peak.telecommunity.com/EasyInstall.html

Please make the appropriate changes for your system and try again.

然后：

Running collectstatic...
Traceback (most recent call last):
  File "~/app-root/runtime/repo//wsgi/music/manage.py", line 2, in <module>
    from django.core.management import execute_manager
ImportError: No module named django.core.management

我试图启用venv并手动运行setup.py：

source $OPENSHIFT_GEAR_DIR/virtenv/bin/activate
export PYTHON_EGG_CACHE=$OPENSHIFT_GEAR_DIR/virtenv/lib/python-2.6
~/app-root/repo/setup.py develop

但是，它导致了相同的can't create or remove files in install directory错误。而且，我也无法manage.py像之前那样在这种环境中运行。

在我看来，venv发生了一些事情，但是后来也gear start使用了它，它仍然有效...

有人可以给我介绍这个问题的重点吗？
