Expected behaviour

I'm using pm2 to manager/monit some binary applications which written by golang.

Actual behaviour

It works pretty well before, after I upgrade pm2 to new version, it seems like set the exec_interpreter to "none" does not work as before, and a error message show up

here is my processes.json

[{
  ...
  "exec_interpreter"  : "none",
  ...
}]

Software versions used

OS         : ubuntu 16.04 LTS
node.js    : v6.70
PM2        : 2.0.18

PM2 Log output

...

Could you just drop the option "exec_interpreter" ?
Btw a fix will land in PM2 to keep the same behavior than v1

[lgn21st]

@Unitech I've removed "exec_interpreter" option and saw this [PM2][ERROR] Interpreter none does not seems to be available

[Unitech]

$ pm2 delete all
$ pm2 start processes.json

[lgn21st]

Same result and there is no exec_interpreter option in processes.json

Tried with exec_interpreter : none and no exec_interpreter, it works.

Could you please show me the ecosystem file

[lgn21st]

@Unitech I'm not sure what is ecosystem file, but after upgrade pm2 to version 2.0.19, I can still get Interpreter none does not seems to be available error message.
