我正在尝试在Macos上安装Anaconda，并且已经下载了.pkg文件。我默认遵循了说明，但是当我运行conda list时，它显示以下错误：
环境
MacOS：10.13.6
conda：4.7.5
Python：Python 3.6.3 :: Anaconda，Inc。
此外，我的Jupiter笔记本电脑没有显示conda选项卡。无法弄清楚环境是什么问题

从zhihu的方法中修复了我的错误
我在这里记录了我的步骤，供其他用户参考：
在Mac上导致此错误的原因是之前已安装Python，我试图删除所有python和Anaconda文件，然后再次安装anaconda，然后成功运行conda命令。
