An unexpected error has occurred. Conda has prepared the above report.
Upload did not complete.

解决办法

1、输入命令行：

conda clean --packages && conda clean --all && conda update --all

2、遇到Proceed(y/n)?

输入y

3、慢慢等，等所有进度条都走完

碎碎念

差点把anaconda卸载了重装，运行升级anaconda的命令也出错，看了提示的错误，一直以为是丢失了repodata_record.json。
