Rebuild C program and run doesn't work

[georgii-ivanov]

#3994 What's going wrong?

How could we reproduce this issue?

I'm trying to run make && ./server for C++ written program in order just watch and restart (recompile and run) Cpp-based microservice.

Supporting information

My PM2 configuration:

{
        "name": "capp",
        "cwd": "./capp",
        "watch": true,
        "script": "make && ./server"
 },

Shows this error:

[PM2][WARN] Applications capp not running, starting...
[PM2][ERROR] script not found : /var/capp/make && ./server

Tried also use /usr/bin/make && ./server but it doesn't work too.
If I run ./server separately that works
I suppose I can use sh file to run both command but make you know the way to avoid it?

@georgii-ivanov could you try again with this pm2:

npm install Unitech/pm2#development -g

Thanks
