【问题描述】：

我不知道为什么我遇到这个错误，当我运行pm2 status时：

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

标签： npm pm2

【解决方案1】：

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

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

【解决方案2】：

您需要在 sudo 中运行它并验证您没有在同一端口上运行的其他进程。

【解决方案3】：

It is a permission error
If you are trying to use pm2 in ubuntu server on EC2 and getting error for error: EACCES and code :-13 

Just follow these steps:
sudo su - to get to the root user permissions
then create an ecosystem.config.js file in the root folder:- 
module.exports = {
  apps : [{
    name: "server",
    script: "server.js"
  }]
}
then write pm2 start server
