mac配置yarn 环境，command not found: yarn，解决无法npm -g的情况
遇到问题：zsh: command not found: yarn
解决方案
前提：电脑已安装node
node -v
全局安装
npm install yarn -g
如果这一步没有问题，就不需要往下看了,可以直接执行 yarn 命令了
如果遇到报错The operation was rejected by your operating system.npm ERR! It is likely you do not have the permissions to access this file as the current user

解决报错方案一：
sudo npm i yarn -g
解决报错方案二：（仅限电脑权限管控严格情况下，无法获取权限）
step1: 查看npm 全局文件安装地址
XXX@CN_CXXXMD6M ~ % npm list -g
/usr/local/lib
├── @quasar/cli@1.3.2
├── corepack@0.14.1
├── npm@8.19.2
└── yarn@1.22.18step2: 从其他人电脑上同样的目录，拷贝出来两份文件，一个是命令的快捷方式文件，一个是环境变量所指的路径文件，粘贴到自己电脑相同位置
-
命令快照文件
-
全局命令所指文件
step3: 打开环境变量配置文件，配置环境变量
vim ~/.bash_profile
把下面内容粘贴到环境变量文件里，
export PATH=/usr/local/lib/node_modules/yarn/bin/:$PATH
保存.bash_profile的编辑，执行一下文件
source ~/.bash_profile
问题解决，大功告成
命令行重新打开，就可以使用yarn
yarn -v
