conda install 下载慢 报错解决

下载失败

​

​conda install xxx​

​ 出现如下报错：

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/win-64/xxxxx.tar.bz2>
Elapsed: -

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.      

解决方法一

出现错误即是下载失败，配置清华大学镜像源：

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      

解决方法二

如果清华大学镜像源里面没有这个库，那么还是会从原来的镜像​

​https://repo.anaconda.com/pkgs/main/​

​里面下载。

这里解决方法是使用​

​迅雷​

​​等其他下载器将​

​.tar.bz2​

​下载到本地，执行本地安装：

conda install --use-local xxxx.tar.bz2
