【问题描述】：
当我在 anaconda 中打开 Spyder 时，Spyder 提示在 Spyder 中启动内核时出错。我已经（在终端中）尝试了来自 Spyder 的两个建议命令。但是，我重启anaconda并打开Spyder后，同样的问题存在，所以不知道如何解决。感谢您的帮助！
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.*
终端中的结果如下所示。
