An error occurred when trying to install django-cms 2.2. Look above this message for any errors that were output by easy_install.
While:
  Installing django.
  Getting distribution for 'django-cms==2.2'.
Error: Couldn't install: django-cms 2.2

Buildout.cfg：

[versions]
django = 1.3
django-registration = 0.8-alpha-1
django-filebrowser = 3.0-no-grappelli-2
django-cms = 2.2

我试过谷歌搜索，它说当 django 版本不是 1.3 时可能会出现此错误，但是这里指定 django 必须是 1.3

有什么想法可以解决这个问题吗？如果你还需要什么，请告诉我。

【问题讨论】：

这是 Django-CMS 包中的一个错误；它正在在安装时自行导入。
@MartijnPieters 我该如何解决这个问题？
为什么要安装这么老版本的django-cms。您正在使用 django 1.6，而且很可能旧版本无论如何都无法工作。我会选择最新的稳定版本 - 3.0.3
这是 2.x 版本的错误；我猜。在this commit 之前你会遇到这些问题；成为 3.x 系列的一部分。

【解决方案1】：

您遇到了一个问题，即您有一个全局可导入的django.conf.settings 模块可用。 django-cms 包直到版本 3.0 依赖于该模块不可在安装期间是可导入的。

发生的情况是，在安装过程中，安装脚本会导入 cms 包以读取版本号，但同一包也会尝试修补您的 Django 设置。这仅由ImportError 异常处理程序保护；例如如果django.conf.settings 的导入失败，则不要修补设置。

当您安装了全局 Django 时，导入不会失败，但是会引发不同的异常，因为您在安装时没有 Django 配置安装 django-cms。

要么升级到 django-cms 3.x，要么删除你的全局 Django 安装。
