An unexpected error has occurred. Conda has prepared the above report.
Upload successful.报错显示RuntimeError: didn't find info component in /home/hwits/anaconda3/pkgs/conda-4.8.2-py37_0.conda，
看提示我的版本是：current version: 4.7.12
最新版本是latest version: 4.9.2
并且提示我要更新conda update -n base -c defaults conda，
但是报错的是conda-4.8.2-py37_0.conda，貌似我也不需要这个版本，
于是尝试删除这个文件：
rm /home/hwits/anaconda3/pkgs/conda-4.8.2-py37_0.conda之前再次安装新环境一切正常。
