Since the image source used is Tsinghua source, Tsinghua source seems to be unusable, so I went to the C drive to find the .condarc file and delete it.
Reconfigure the mirror source: the following is from the University of Science and Technology of China
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/main/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/cloud/conda-forge/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/cloud/msys2/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/cloud/bioconda/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/cloud/menpo/
conda config --set show_channel_urls yes
According to this, enter the source in the environment, and then re-enter the command installation command
Finish!
After working for a long time, I added a lot of mirror sources, and forgot to modify the address of the source, which is a tragedy. . . .
