一、问题

环境

系统：centos 7
node ：v18.16.1
npm：9.5.1

安装pm2

npm install -g pm2

提示报错：

npm WARN deprecated uuid@3.4.0: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.changed 184 packages in 17s12 packages are looking for fundingrun `npm fund` for details

二、解决

更新uuid

npm install uuid@latest -g

更新成功后，继续安装pm2，也会提示：npm WARN deprecated uuid@3.4.0: Please upgrade to version 7 or higher.

其实是已经安装成功了

1、查找pm2的安装位置

find / -name pm2

/usr/local/lib/node_modules/pm2
/usr/local/lib/node_modules/pm2/lib/templates/logrotate.d/pm2
/usr/local/lib/node_modules/pm2/bin/pm2
/usr/local/lib/node_modules/pm2/pm2

2、增加pm2软链接

ln -s /usr/local/lib/node_modules/pm2/bin/pm2 /usr/local/bin

查看pm2版本

pm2 -v
即可
