在 Anaconda 3 中安装软件包时出错答案

【问题标题】：Error when installing packages in Anaconda 3在 Anaconda 3 中安装软件包时出错

【问题描述】：

最近我一直在努力使用 anaconda 安装任何软件包（顺便说一句，我不是 python/anaconda 的专家）。无法安装我想要的软件包是一致的（与以前不同）。以下错误报告是我尝试安装cartopy时的示例。

谁有同样的经历？在过去的几天里，我安装的每个软件包都向我显示相同的错误，这太奇怪了。我正在使用 Spyder (Python 3.7) 和 Anaconda 3。

【问题讨论】：

您是在使用 Spyder 还是一些 GUI 来安装软件包，还是从命令行运行某些东西？
这里有问题的行是ValueError: Unregistered SAT variable name for conda-forge/win-64::mysql-connector-python-8.0.27-py37h0612672_0。令人惊讶的是，网上并没有太多提到这个错误，所以很少见。可能类似于以前中断的安装。您可以尝试删除或重新安装 mysql-connector-python 吗？似乎包安装与它有关。
鉴于没有安装工作，我认为完全重新安装 Anaconda 是必要的
