当我在anaconda中打开Spyder时，Spyder指示在Spyder中启动内核时发生错误。我已经尝试了（在终端中）来自Spyder的两个建议命令。但是，重新启动anaconda并打开Spyder后，仍然存在相同的问题，因此我不知道如何解决该问题。谢谢您的帮助！
以下是Spyder打开时的内容：
An error occurred while starting the kernel
Your Python environment or installation doesn't have the spyder‑kernels module or the right version of it installed. Without this module is not possible for Spyder to create a console for you.
You can install it by running in a system terminal:
conda install spyder‑kernels=0.*
or
pip install spyder‑kernels==0.*
终端中的结果在下面列出。

如果@lyq 的解决方案不起作用，这对我有用。
打开 Anaconda 提示符并运行以下行：
spyder --reset
