If you use PM2 via node modules instead of globally  you ll need to set interpreter   none  in order for the above solutions to work  Related docs here   In ecosystem config js     apps                name   myApp         script   yarn         args   start         interpreter   none

Those who are using a configuration script like a  json file to run the pm2 process can use npm start or any other script like this -   my-app-pm2 json         apps                            name    my-app                script    npm                args     start                      Then simply -   pm2 start my-app-pm2 json   Edit - To handle the use case when you have this configuration script in a parent directory and want to launch an app in the sub-directory then use the cwd attribute   Assuming our app is in the sub-directory nested-app relative to this configuration file then -           apps                            name    my-nested-app                cwd      nested-app                script    npm                args    start                      More detail here
