You are missing a start script in your package.json

Error while executing "npm start" command

I installed npm and changed the package.json file so that it can automatically compile the .scss file into a css file when npm start is used. the changes made are as follows.
"scripts": {
"start": "npm run watch:all",
"test": "echo \"Error: no test specified\" && exit 1",
"lite": "lite-server",
"scss": "node-sass -o css/ css/",
"watch:scss":"onchange \"css/*.scss\" -- npm run scss",
"watch:all":"parallelshell \"npm run watch:scss\" \"npm run lite\""
},
but when I run the "npm start" command it returns an error. The error is as follows.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! confusion#1.0.0 watch:all: `parallelshell "npm run watch:scss" "npm run lite"`

please help me solve this problem,
I want to complete my project but this error is in my way.

It is a bug from parallelshell. We will have to manually edit file to fix this error
You need to go to the file:
node_modules/parallelshell/index.js:105
Then change this line:
cwd: process.versions.node < '8.0.0' ? process.cwd : process.cwd(),
To this:
cwd: parseInt(process.versions.node) < 8 ? process.cwd : process.cwd()
Then things will work well

Local package.json exists, but node_modules missing, did you mean to install?

You should have found the answer by now but if someone else find it useful, just run npm install in your console.

Write npm start in the terminal followed by npm install. This will solve your issue.

Why npm start is not working and giving the following error messages:

I have one question regarding npm. Whenever I start npm, it gives the following error:
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! pomodorclock#1.0.0 start: `node index.js`
npm ERR! Exit status 1

npm WARN Local package.json exists, but node_modules missing, did you mean to install?

You first need to run npm install before you can build the package. After you can use npm start.
