python - conda 环境如何干扰系统安装？

Question

我（有）系统安装了 python 2.7，keras 和 tensorflow 工作正常。

今天我创建了一些新的 conda 环境，并在其中安装了几个包，包括更新的 tensorflow 版本。

我所做的所有安装都首先激活了感兴趣的环境，并使用conda install和/或pip install在环境内部（每当我之前在所述环境中执行 conda install pip 时使用 pip）。

现在，由于某种原因，在停用所有 conda 环境并返回我的系统“环境”（没有激活的 conda）之后，我无法再导入 keras 或 tensorflow，两者都在抱怨某些模块"gast"（请参阅下面的错误消息）。

这令人费解，因为 conda 不应该接触环境之外的任何东西。我的 python 和模块都在 conda 之外。

which pip, which spyder, which python..等等，都指向/usr/bin

可能出了什么问题？以及如何修复损坏的系统模块？

我的系统安装了使用 pip 完成的 keras 和 tensorflow。康达的点子会干扰他们吗？
