我仍然收到此错误：启动内核时发生错误

我尝试过的事情：

setuptools 命令
更新 spyder
从卸载或更改程序面板中卸载了包含 python 的所有内容
卸载并重新安装 anaconda
阅读人们对如何尝试解决问题的回复
尽量不感到沮丧。

这在我更新了我不应该拥有的 spyder 之后开始发生，但现在我被这个问题所困扰。我将分享我的 IPhython 控制台屏幕上出现的完整消息。

标签： python installation anaconda spyder

【解决方案1】：

问题是你安装了两个 Python 版本：

C:\Users\afsan\Anaconda3\
C:\Users\afsan\AppData\Local\Programs\Python\Python36

鉴于您似乎想将 Spyder 与 Anaconda 一起使用，请删除您的第二个 Python 版本（如有必要，请手动删除）。这应该可以解决您的问题。

【讨论】：

哈！我希望你能以某种方式回复这个问题。无论如何，我想出了什么问题。谢谢你的光。我现在意识到，当你执行 pip install 时，它会将东西安装到你原来的 python 库中，而 conda install 会将东西安装到 conda 目录中。另外，我通过 pip 更新了 spyder，我假设我在 spyder 中给出了它的路径（我不记得但我能以某种方式回忆起来），但是，python 版本仍然是旧版本。因此，这两个版本让我很难受。非常感谢您的快速回复。 :)
