笔记

test报错 Test suite failed to run / Cannot find module ‘request’

Something is up with your installed tree, doing npm dedupe && npm prune && npm install makes the test green.

安装yarn

sudo npm i -g yarn
通过上图，可以找到yarn的路径为/usr/local/bin/yarn，我们将其添加到~/.bash_profile中即可，
open ~/.bash_profile
具体添加以下：
export PATH="$PATH:`/usr/local/bin/yarn`"
保存后，让这个环境变量生效
source ~/.bash_profile
然后再执行yarn -version，已然ok
