Question

我认为当我做一些brew更新的东西时，这已经变成了foobarred。每次调用我的系统python3时，它都会发出：

Error in sitecustomize; set PYTHONVERBOSE for traceback:  
KeyError: 'PYTHONPATH'

这特别令人烦恼，因为我在终端中使用powerline，而powerline每次执行命令时都会调用python。

用我得到的详细标志调用Python3：

$ PYTHONVERBOSE=True python3

<multiple pages of python startup info...>

# bytecode is stale for 'sitecustomize'

因此系统Python3正在尝试加载sitecustomize的Python2版本？我怀疑那是问题所在。如果是这样，我可以选择解决这个问题？ brew unlink python3 && brew link python3没有帮助。

我不确定bytecode is stale for 'sitecustomize'评论python的用途是什么，但我也删除了sitecustomize.pyc文件，但没有帮助。

“KeyError：'PYTHONPATH'”。在python3中破坏了Sites.py？
