我是vim的新用户。我正在尝试使Vim编辑器成为python IDE。通常，我将virtualenv用于python工作。
所以问题是vim-editor在一个环境中似乎可以正常工作，而在不同的环境中却引发错误。两种环境（假设env1和env2）具有相同的依赖关系。但是两者都会显示出不同的系统路径结果。
Env1

您可能会注意到 Env1 的路径与 / System / Library / Frameworks / 相关，而 Env2 的路径与 / usr相关/local/Cellar/python@2/2.7.14_3/Frameworks / 。我不明白为什么会这样。
当我在 env1 中打开文件时，它会正常打开，但是当我在 env2 中打开文件时，它将引发给定的错误。

env2 中的python依赖关系在下面给出
$ pip freeze
ipython==5.8.0
jedi==0.12.1
rope==0.10.7
ropemode==0.4
ropevim==0.7.0
我不明白，env2出了什么问题？任何帮助，将不胜感激。谢谢。
