conda install numpy失败的问题解决

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --set show_channel_urls yes 

然后就会在~/.condarc里看到

 channels:  
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/   
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/  
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/  
- default  
show_channel_urls: true

将 - default 那一行删掉 保存.condarc .然后重启终端就能用conda安装新的库了
