An unexpected error has occurred. Conda has prepared the above report.
If you suspect this error is being caused by a malfunctioning plugin,
consider using the --no-plugins option to turn off plugins.
Example: conda --no-plugins install <package>
Alternatively, you can set the CONDA_NO_PLUGINS environment variable on
the command line to run the command without plugins enabled.
Example: CONDA_NO_PLUGINS=true conda install <package>

错误原因
这个错误是与字符编码相关的问题，可能是由于终端在尝试将某个特殊字符以GBK编码（Windows似乎默认是GBK编码）写入输出时出现了问题。
解决这个问题的方法通常是将终端的编码设置更改为支持更广泛字符集的编码，如UTF-8。
解决办法
VSCode的解决办法是在settings.json中加入：
{
"terminal.integrated.env.windows": {
"PYTHONIOENCODING": "utf-8",
},
}即可设置终端编码，重启后生效。
