MAC OS系统替换brew.npm, pip 使用阿里云的镜像源

替换brew.git:
cd "$(brew --repo)"
git remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git
# 替换homebrew-core.git:
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git
# 应用生效
brew update
# 替换homebrew-bottles:
echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.bash_profile
source ~/.bash_profile

npm 改淘宝源，//将registry设置为淘宝镜像

npm config set registry http://registry.npm.taobao.org

查看registry

npm config get registry

mac

在终端进入目录：cd ~/

mac用户家目录如果没有 .pip 文件夹，那么就要新建这个文件夹

mkdir .pip

然后在.pip 文件夹内新建一个文件

vi pip.conf

编辑 pip.conf 文件，写入阿里云

cd ~/

mkdir .pip

vi pip.conf
