Django：属性错误：模块'collections'没有属性'Iterator'

Question

使用django-admin startproject trydjango会出现错误：

属性错误：模块"collections"没有属性"Iterator"

即使我安装了Django，并且可以通过执行django-admin看到命令列表。

以下是完整的错误：

我正在遵循本教程，并使用其中提到的内容，但我仍然会遇到这个错误，而老师没有。也在使用macOS。

Answer 1

尝试为您的项目使用另一个名称。

CommandError:"test"与现有Python模块的名称冲突，不能用作项目名称。请尝试其他名称。

Answer 2

此错误可能是env的原因。我也有同样的问题。制作新的env，然后尝试制作新的项目。
