当我在anaconda中打开spyder时，spyder指示在spyder中启动内核时出现错误

Question

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，在我重新启动anaconda并打开Spyder之后，同样的问题仍然存在，所以我不知道如何解决这个问题。谢谢你的帮助!

以下是Spyder打开时说的话：

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。

Answer 1

您可以尝试：

conda install spyder-kernels

或

pip install spyder-kernels

Answer 2

如果@lyq的解决方案不起作用，这对我来说是有效的。

打开Anaconda提示符并运行以下代码行：

spyder --reset

Answer 3

检查here提供的spyder-kernel的兼容版本，并使用pip安装，如下所示-

pip install spyder-kernels== COMPATIBLE VERSION
