You are trying to instal PM2 as /usr/local/bin/pm2 and you need root access for that.

您正在尝试将PM2安装为/ usr / local / bin / pm2，并且您需要root访问权限。

Instead of:

代替：

npm install pm2 -g

you need:

你需要：

sudo npm install pm2 -g

Note that you need to be in the sudoers group.

请注意，您需要进入sudoers组。

Alternatively you can install Node in your home directory instead of system-wide and then you won't need sudo for install -g

或者，您可以在主目录而不是系统范围内安装Node，然后安装-g就不需要sudo了
