How to fix "Npm ERR! JSON.parse Unexpected string in JSON at position 228.."

I am trying to start NPM after installing it but the start errors out.

I couldn't find syntactical errors in the 'package.json' file I couldn't find the error log I tried reinstalling I tried clearing my cache All without success

Here is my 'package.json' file:

{
  "name": "git-test",
  "version": "1.0.0",
  "description": "test json file",
  "main": "index.js",
  "dependencies": {},
  "devDependencies": {
    "lite-server": "^2.4.0"
  },
  "scripts": {
    "start": "npm run lite"
    "test": "echo \"Error: no test specified\" && exit 1"
    "dev": "lite-server"
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/Master-Hippo/Front-End_Web_UI_Frameworks_and_Tools.git"
  },
  "author": "Master-Hippo",
  "license": "ISC",
  "bugs": {
    "url": "https://github.com/Master-Hippo/Front-        
End_Web_UI_Frameworks_and_Tools/issues"
  },
  "homepage": "https://github.com/Master-Hippo/Front-    
End_Web_UI_Frameworks_and_Tools#readme"

Here is the error log:

npm ERR! code EJSONPARSE
npm ERR! JSON.parse Failed to parse json
npm ERR! JSON.parse Unexpected string in JSON at position 228 while parsing 
'{
npm ERR! JSON.parse   "name": "git-test",
npm ERR! JSON.parse   "version": "1.'
npm ERR! JSON.parse Failed to parse package.json data.
npm ERR! JSON.parse package.json must be actual JSON, not just JavaScript.

And, although the message says an error log was created in a specific folder, none actually exists in said folder.

How can I resolve this issue?

Also note sometimes this issue can occur even if there is no missing comma in package.json file. This occurs due to node version.

In my case, I hade node version 14.17.1 installed on my system and the repo was working in 16.xx.xx version and I faced this issue, and once i upgraded node the problem got resolved.

So also keep this point in mind.

Try validate your package.json with jsonlint

I guess that your file could be like this:

{
    "name": "git-test",
    "version": "1.0.0",
    "description": "test json file",
    "main": "index.js",
    "dependencies": {},
    "devDependencies": {
        "lite-server": "^2.4.0"
    },
    "scripts": {
        "start": "npm run lite",
        "test": "echo \"Error: no test specified\" && exit 1",
        "dev": "lite-server"
    },
    "repository": {
        "type": "git",
        "url": "git+https://github.com/Master-Hippo/Front-End_Web_UI_Frameworks_and_Tools.git"
    },
    "author": "Master-Hippo",
    "license": "ISC",
    "bugs": {
        "url ": "https://github.com/Master-Hippo/Front-End_Web_UI_Frameworks_and_Tools/issues"
    },
    "homepage": "https://github.com/Master-Hippo/Front-End_Web_UI_Frameworks_and_Tools#readme"
}

Your package.json should be valid json like this:

{
    "name": "git-test",
    "version": "1.0.0",
    "description": "test json file",
    "main": "index.js",
    "dependencies": {},
    "devDependencies": {
        "lite-server": "^2.4.0"
    },
    "scripts": {
        "start": "npm run lite",
        "test": "echo \"Error: no test specified\" && exit 1",
        "dev": "lite-server"
    },
    "repository": {
        "type": "git",
        "url": "git+https://github.com/Master-Hippo/Front-End_Web_UI_Frameworks_and_Tools.git"
    },
    "author": "Master-Hippo",
    "license": "ISC",
    "bugs": {
        "url": "https://github.com/Master-Hippo/Front-End_Web_UI_Frameworks_and_Tools/issues"
    },
    "homepage": "https://github.com/Master-Hippo/Front-End_Web_UI_Frameworks_and_Tools#readme"
}

There were a few commas missing.
