Mac 安装 Dart 环境一直 显示 Updateing Homebrew...

Mac通过命令安装 Dart，一直卡住不动，如下

jason@local homebrew-core$ brew tap dart-lang/dart
Updating Homebrew...

解决方案

网上资料都是说改下.git仓库的镜像地址,切换后还是要等的

# 使用中科大的镜像
cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
 
# 使用中科大的 homebrew-core.git 仓库地址:
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
source ~/.bash_profile

安装 dart

jason@local Homebrew$ brew install dart --devel

安装完毕后，可以选择切换回官方源

# 第一步：重置brew.git
cd "$(brew --repo)"
git remote set-url origin https://github.com/Homebrew/brew.git

#第二步：重置homebrew-core.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://github.com/Homebrew/homebrew-core.git

#第三步：注释掉bash配置文件里的有关Homebrew Bottles即可恢复官方源。 重启bash或让bash重读配置文件
