Question

我已经安装了Anaconda 2，所以我的基本python版本是2.7。我可以使用

创建各种虚拟环境

conda create --name new_27 python=2.7

激活该环境后，该环境将按预期工作。但是，如果我安装python 3.x版，它将失败。安装进行时没有警告，我可以激活它。但是在那里执行任何操作都会产生以下错误消息（无论我运行什么，我总是会收到相同的错误消息）

看来您的Python 3 conda环境可能正在尝试访问基本环境中的软件包。

这些步骤应尝试通过删除Python 3环境来补救。清理所有残留的包装；更新conda;然后重新创建环境。

conda env remove -n py36
conda clean -tipsy
conda update conda -y
conda create -n py3 python=3.6

如果这不起作用，则可能必须重新安装Anaconda。
