将ReadTheDocs托管在python3的家庭服务器中时出错

Question

我试图在本地系统(Ubuntu14.04)中安装python3虚拟env中的readthedocs。

当我运行pip3 install -r requirements.txt时，出现了Distutils2错误。我消除了这种依赖，因为distutils2不再受支持，并且假设setuptools就足够了。

运行此命令python manage.py迁移会产生以下错误：

我从上面的堆栈跟踪中了解到，代码在python2中，所以print语句在python3中是不同的。

这是否意味着我必须在python2虚拟文件中安装readthedocs？

我们不能在readthedocs内部服务器中托管python3项目的文档吗？

Answer 1

读取文档代码还不支持Python 3。安装说明明确表示要使用Python2.7：

首先，获取Python2.7和virtualenv

但是，仍然可以使用读取的docs安装来托管Python 3项目的docs，因为说明随后说：

如果您计划将Python3项目导入到您的RTD中，那么您还需要在您的系统中安装带有virtualenv的Python3。
