所以我设置了使用 django 1.3 和 zc.buildout 的旧 python 项目。当我运行服务器时，出现以下错误:

据我所知，django.utils.text 中的 Truncator 类不在 django 1.3 中。如果我不得不猜测某个模块，其版本未在 buildout 中指定，则使用此类，但当该项目在 django 1.3 上构建时则没有指定。
我说得对吗？是否 - 我在这里有什么选择？
最佳答案
Truncator 类已添加到 Django 1.4 中。显然您安装的 django-extensions 版本需要 Django 1.4 或更高版本；正是该包尝试进行此导入。
您必须找到适用于您的 Django 1.3 设置的该软件包的旧版本。
查看 django-extensions GitHub 存储库，您可以看到它们 removed compatibility for older Django versions去年11月。 GitHub UI 向我们显示，包含该提交的最早标签是 1.3，因此之前的版本应该仍然有效。根据 GitHub 标签列表和 django-extensions PyPI information，该版本似乎是 2.5。 .
将该包固定在您的版本部分:
[versions]
# ...
django-extensions = 1.2.5
