bash:pm2:找不到命令

Question

我无法在ubuntu框上运行pm2.我不确定是什么问题.pm2全局安装.

npm list -g --depth=0
/opt/nodejs/lib
??? forever@0.15.3
??? node-gyp@3.4.0
??? npm@2.15.9
??? pm2@2.1.5
??? userdown@0.2.1
??? wait-for-mongo@0.2.0

但我还是得到了

pm2
-bash: pm2: command not found

如果我运行其他应用程序

userdown
Starting Script is not provided

版本

node v4.5.0
npm  v2.15.9

从安装日志:

ubuntu版本:

uname -a

Answer 1

好的,我自己回答.我检查一下会发生什么

whereis pm2
pm2: /opt/nodejs/bin/pm2

然后我查了一下

whereis userdown
userdown: /usr/bin/userdown /usr/bin/X11/userdown /opt/nodejs/bin/userdown

嗯/ usr/bin ....所以我做到了

sudo ln -s /opt/nodejs/bin/pm2 /usr/bin/pm2 

它的工作原理:)
