網上有網友說加上超時時間，但並沒有解決我這個問題。

pip --default-timeout=100 install docker-compose

 

這個應該是沒有FQ導致下載超時。所以需要修改pip 的源

按照網上例子，臨時修改了pip的源，再次執行安裝命令，也沒有解決我的問題

[root@localhost bin]# pip install numpy -i https://pypi.tuna.tsinghua.edu.cn/simple/

 

后來又看到一篇博客，這種方式解決了我的問題，修改源借鑒的是https://blog.csdn.net/h106140873/article/details/103858931 博客。

1：在根目錄下創建pip文件夾（我是使用的root用戶）

mkdir ~/.pip

2：在 .pip目錄中創建 pip.conf文件

 touch pip.conf

 3：編輯 pip.conf 文件，添加如下兩行內容

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

 

再次執行 pip --default-timeout=100 install docker-compose 命令，安裝成功。並且下載速度很快
