`$ C:\Users\hp\AppData\Local\r-miniconda\Scripts\conda-script.py info-e`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>If submitted, this report will be used by core maintainers to improve
future releases of conda.
Would you like conda to send this report to the core maintainers? [y/N]:

突然出现以上报错后，卸载miniconda：

1. 删除miniconda安装目录下的envs及pkgs文件夹；
2. 运行miniconda安装目录下的Miniconda unistall.exe应用程序，来卸载软件包。

卸载后在R中重新安装，出现以下报错：
