1、鏡像源查看

$ conda config --show-sources

2、國內(nèi)第三方源添加

conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --add channels https://anaconda.mirrors.sjtug.sjtu.edu.cn/pkgs/main
conda config --add channels https://anaconda.mirrors.sjtug.sjtu.edu.cn/pkgs/free
conda config --add channels https://anaconda.mirrors.sjtug.sjtu.edu.cn/pkgs/mro
conda config --add channels https://anaconda.mirrors.sjtug.sjtu.edu.cn/pkgs/msys2
conda config --add channels https://anaconda.mirrors.sjtug.sjtu.edu.cn/pkgs/pro
conda config --add channels https://anaconda.mirrors.sjtug.sjtu.edu.cn/pkgs/r

3、刪除源

$ conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/

4、源報(bào)錯(cuò)處理

報(bào)錯(cuò)：

(base) root@ecs-88e2:~# conda create scanpy python=3.7

CondaValueError: The target prefix is the base prefix. Aborting.
