yarn介绍:
Yarn是facebook发布的一款取代npm的包管理工具
yarn特点:
速度超快:Yarn 缓存了每个下载过的包,所以再次使用时无需重复下载。 同时利用并行下载以最大化资源利用率,因此安装速度更快。
超级安全:在执行代码之前,Yarn 会通过算法校验每个安装包的完整性。
超级可靠:使用详细、简洁的锁文件格式和明确的安装算法,Yarn 能够保证在不同系统上无差异的工作。
然而在Mac下安装会遇到问题:报没权限安装问题,如下所示:
npm install -g yarn

出现这个问题,我们可以采用以下命令执行,也就是加速sudo
sudo npm install -g yarn
