anaconda3 | 镜像管理

如果需要安装很多packages，会发现conda下载的速度经常很慢，因为Anaconda.org的服务器在国外。所幸的是，清华TUNA镜像源有Anaconda仓库的镜像，我们将其加入conda的配置即可：

# 添加Anaconda的TUNA镜像
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

# 设置搜索时显示通道地址
conda config --set show_channel_urls yes

执行完上述命令后，会生成~/.condarc(Linux/Mac)或C:\Users\USER_NAME.condarc文件，记录着我们对conda的配置，直接手动创建、编辑该文件是相同的效果。

显示安装的频道

 conda config --set show_channel_urls yes 

查看已经添加的channels

conda config --get channels

已添加的channel在哪里查看

vim ~/.condarc

增加镜像：conda config --add channels url

conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free           
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 --set show_channel_urls yes 

显示镜像

conda config --show

删除镜像：conda config --remove channels url

conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
