How to solve Error: EACCES: permission denied in pm2?

Question

我不知道为什么会遇到这个错误，当我 运行 pm2 status:

kaitoSwift@kaito-MacBook-Pro school-sms2 % pm2 status
node:internal/fs/utils:344
    throw err;
    ^

Error: EACCES: permission denied, open '/Users/kaitoSwift/.pm2/pm2.log'
    at Object.openSync (node:fs:585:3)
    at module.exports.Client.launchDaemon (/usr/local/lib/node_modules/pm2/lib/Client.js:228:12)

  errno: -13,
  syscall: 'open',
  code: 'EACCES',
  path: '/Users/kaitoSwift/.pm2/pm2.log'
}

当我尝试使用 npm install pm2 -g 下载 pm2 时：

kevintrinidad@kaito-MacBook school-sms2 % npm install pm2 -g 
npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/pm2

Answer 1

您需要 运行 在 sudo 中执行此操作，并确认您在同一端口上没有 运行 的其他进程。

Answer 2

要安装 PM2，请使用：

sudo npm install -g pm2

对于pm2 status的错误，同样尝试：

sudo pm2 status

错误告诉你 /Users/kaitoSwift/.pm2/pm2.log 不存在。
