安装python包出现连接错误：
问题描述
Collecting package metadata (current _repodata. json) : failed CondaHTTPError: HTTP 000 CONNECTION FAILED for url (https://repo. anaconda. com/pkgs/main/win-64/ 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. If your current network has https://www.anaconda.com blocked, please file a support request with your network engineering team 'https://repo. anaconda. com/pkgs/main/win-64
原因分析：
显示CONNECTION FAILED表示连接失败，最后两行显示了解决方案，把镜像源换成 'https://repo. anaconda. com/pkgs/main/win-64
我原来配置的镜像源是清华源：想着重新配置一下
但是依旧不行!
解决方案：
根据提示，把镜像源换成 'https://repo. anaconda. com/pkgs/main/win-64
进入目录: C:Userslenovo下，删除.condarc文件（该文件是conda的配置文件）之后可以重新生成！
输入conda命令：conda config --remove-key channels恢复Anaconda的源为默认
重新输入conda配置镜像源命名：
# 必要时：删除镜像源 conda config --remove channels 'https://mirrors. tuna. tsinghua. edu. cn/anaconda/pkgs/free' conda config --remove channels 'https://mirrors. tuna. tsinghua. edu. cn/anaconda/pkgs/main` # 添加镜像源地址 conda config --add channels 'https://repo. anaconda. com/pkgs/main/win-64' # 让镜像源地址生效 conda confie --set show_channel_urls yes # 查看是否配置好新的镜像源 conda config -show-sources
这是成功了！
虽然这次成功了，但因为毕竟是外网的镜像源，免不了因为网速问题之后还需要配置国内镜像源！！！
