如何运行写在外部js文件中的npm脚本（package.json）？

Question

I know it has been covered in different questions but mine is a bit different: Sorry in advance if it sounds really noob.

this is the script in package.json:

"start": "nodemon ./index.js --exec \"node -r babel-register\"",

I replaced by :

"start": "node scripts/start.js",

and in start.js, i do :

const { execSync } = require('child_process')

execSync('nodemon ../index.js --exec \"node -r babel-register\"')

wich throw an error :

/bin/sh: nodemon: command not found

Am I right with "execSync" ?

I tried import nodemon in the file but it obviously not helping

What you're doing should work if nodemon is installed globally, ie with:

npm install -g nodemon

But if it's installed as a project dependency, ie with:

npm install --save-dev nodemon

Then you'll need to run it from the directory containing all the locally installed binaries: node_modules/.bin/

So something like this should work:

execSync('./node_modules/.bin/nodemon ../index.js --exec \"node -r babel-register\"')
