无法在 Emacs Shell 中激活 Conda 环境

Question

将 MacOS 升级到 Mojave 后，我注意到我无法再在 Emacs shell 中激活 conda 环境。在普通 MacOS 终端中，激活仍然有效。

在 Emacs 中创建 shell 时，出现以下错误：

    ImportError: cannot import name 'InvalidSchemeCombination' from 'pip._internal.exceptions' (/User
    s/user/miniconda3/lib/python3.7/site-packages/pip/_internal/exceptions.py) 

如果我尝试用 Pip 做某事，我会得到这个：

感谢有关如何解决此问题的任何帮助。升级前一切正常。 Emacs 配置没有改变。
