PIP安装docker-compose超时问题解决方案（docker-compose安装失败）

1：安装命令

pip install docker-compose

异常信息

网上有网友说加上超时时间，但并没有解决我这个问题。

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

这个应该是没有翻墙导致下载超时。所以需要修改pip 的源

按照网上例子，临时修改了pip的源，再次执行安装命令，也没有解决我的问题

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

后来又看到一篇博客，这种方式解决了我的问题，修改源借鉴的是https://blog.csdn.net/h106140873/article/details/103858931 博客。

1：在根目录下创建pip文件夹（我是使用的root用户）

mkdir ~/.pip

2：在 .pip目录中创建 pip.conf文件

touch pip.conf

3：编辑 pip.conf 文件，添加如下两行内容

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

再次执行 pip --default-timeout=100 install docker-compose 命令，安装成功。并且下载速度很快

注：pip国内的一些镜像
