Task not found

[joeprivettsmart]

I am running this command in my Mac terminal:

joe.bloggs$ yarn run start

but I get the output:

yarn run v1.22.15 $ npm-run-all -s "yarn start:backend" "yarn start:frontend" ERROR: Task not found: "yarn"

Clearly I have yarn installed otherwise it wouldn't be able to run yarn run start, so why does npm-run-all not find the yarn command?

npm-run-all is for running npm scripts, not arbitrary shell commands.

You might need to change your package.json file like this:

{
	// ...
	"scripts": {
-		"start": "npm-run-all -s \"yarn start:backend\" \"yarn start:frontend\"",
+		"start": "npm-run-all -s start:backend start:frontend",
		"start:backend": "...",
		"start:frontend": "...",
		// ...
	}
}

If you need to run them using yarn for whatever reason, then npm-run-all isn't the right tool for the job.
