The error you're getting is because a bash script (yarn) is being executed with node...

Because pm2's default interpreter is set to node.

To run yarn you'll have to set the interpreter to bash:

shell:

Try the command below:

pm2 start yarn --interpreter bash --name api -- start

Helped me a lot. Let me mention also that if your script name is something else than `start`, then you only have to replace the final `start` by your new script name. (i.e: `pm2 start yarn --interpreter bash --name api -- start:prod` if I use `yarn run start:prod`). – Ryo Shiina Nov 12 '20 at 15:44
is there a way to run this command with sudo access? I got permission access denied when running yarn start on port 80 – Darryl RN Jul 06 '22 at 02:03

For me (on ubuntu 20)

pm2 start yarn --name api -- start

would do the trick. With the bash interpreter flag it would error in pm2.

Thank you! the bash interpreter flag made it fail on ubuntu 20! – oBo Nov 05 '21 at 12:18
with option 'watch' , you can make an app enable with watch & reload. start with *'--watch'* option, or simply you can restart by `pm2 restart _app-id_ --watch` – agfe2 Jun 17 '22 at 07:33

pm2 start yarn --name api -- start

Won't work for me.

It displays below

0|api      | /usr/share/yarn/bin/yarn:2
0|api      | argv0=$(echo "$0" | sed -e 's,\\,/,g')
0|api      | SyntaxError: missing ) after argument list

It means launching a yarn binary file with a node.js

How about this command.

pm2 start "yarn start" --name api

It work's like charm for me.

What is the `PM2` for command `yarn run start`?
