I'm trying to install npm and I keep getting errors. Initially the problem was I needed a package-lock.json file and package.json file and that was solved by typing "npm init" into the terminal.
Then when trying to run "npm start" it said I was missing the start script. So I opened the package.json file to add it as shown below:
{
"name": "arvinder",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"start": "node index.js"
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC"
}
Now I'm getting the following errors:
Arvinders-MacBook-Air:~ Arvinder$ npm start
npm ERR! file /Users/Arvinder/package.json
npm ERR! code EJSONPARSE
npm ERR! JSON.parse Failed to parse json
npm ERR! JSON.parse Unexpected string in JSON at position 137 while parsing '{
npm ERR! JSON.parse "name": "arvinder",
npm ERR! JSON.parse "version": "1.'
npm ERR! JSON.parse Failed to parse package.json data.

npm ERR! A complete log of this run can be found in:
npm ERR! /Users/Arvinder/.npm/_logs/2020-07-24T16_26_18_155Z-debug.log
I'm not sure where the error is in the json file or why it can't parse it so if anyone could help point out a solution that would be greatly appreciated.
Seems like you're missing a comma in line 7, after "start": "node index.js". Here's the correct one:
{
"name": "arvinder",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"start": "node index.js",
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC"
}
I recommend you to install an extension for your IDE that can catch syntax errors on JSON files.
I suggest you use vscode.
It will throw an error when you missing a comma.
For example:

I wrote the script "style", but for some reason does not want to execute it.
Using the npm run command, you can just execute the script "test": "echo "Error: no test specified" && exit 1"
My package.json is below, as well as the full error message when I run a command:
{
"name": "plants",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"style": "sass sass/style.scss sass/style.css",
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC"
}
here I am trying to run a sktipt:
npm run style
npm ERR! Missing script: "style"
npm ERR!
npm ERR! To see a list of scripts, run:
npm ERR! npm run
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\GRAFIK548\AppData\Local\npm-cache\_logs\2022-12-28T06_18_17_306Z-debug-0.log
and here I look at what scripts can be run:
$ npm run
Lifecycle scripts included in plants#1.0.0:
test
echo "Error: no test specified" && exit 1
in general, I'm trying to connect sass via json
thank you very much for any answer!!
NPM err missing script fix
I used to get this error a lot on my old computer. The easiest fix I found that worked was to just
Try to use the absolute path of the file in your JSON.
I get this error when I run npm start.

package.json has various sections, scripts is one of them, which allows you to write npm scripts which we can run using npm run <script-name>. The error you're getting is because your start script is missing in that section.
For a node app, your package.json file should look similar to this.
{
"name": "server",
"version": "1.0.0",
"description": "",
"main": "app.js",
"scripts": {
"start": "node app.js",
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC",
"dependencies": {
"body-parser": "^1.20.0",
"cors": "^2.8.5",
"express": "^4.17.3"
}
}
In the above code, focus on the scripts section. The following line is missing in your package.json file.
"scripts": {
"start": "node app.js",
},
Add this line and you're good to go.
Option_1: Control inside file "package.json":
"scripts": {
"start": "what command is here?",
},
Option_2: Control Terminal (folder) where you write command OR open the responding terminal for your project: right-click
on the project name -> "Open in integrated Terminal"
You have to put what command you need npm to run when you give npm start.
You have to write node index.js in scripts.start in your package.json file
i did a fresh "npm init". put entry point : "index.html"
then installed lite-server : npm install lite-server --save-dev
also updated the package.json and I Uninstalled, reinstalled tried everything but it's not working and
also tried npm cache clean --force but it's not working. can any one help with this error.
{
"name": "git-test",
"version": "1.0.0",
"description": "",

"lite": "lite-server"
},

"dependencies": {
"lite-server": "^2.5.4"

}
But when I did "npm start" , getting this error

I was too facing the same issue after a system shutdown, hence this worked for me:
First uninstall the current local lite-server in node_modules
npm uninstall lite-server
Install lite-server globally and try running the same command
npm install -g lite-server
then hit:
npm start
This fixed the issue for me, thank you
Here's my Json file script if you want to have a look
"scripts": {
"start": "npm run lite",
"test": "echo \"Error: no test specified\" && exit 1",
"lite": "lite-server"
},
You don't seem to have node/npm installed and configured properly (PATH issues).
I would suggest you try to re-install Node.js using the official instructions for your platform (https://nodejs.org/en/download/) or by using a Node.js version manager like nvm (https://github.com/nvm-sh/nvm) or n (https://github.com/tj/n).
Using nvm or n, will allow you to dynamically switch Node.js version without having to re-install everything from scratch.
Just install the live-server globally,i think that should solve the issue.
sudo npm install --global lite-server
And in your package.json file you can change a little bit.
{
"name": "git-test",
"version": "1.0.0",
"description": "",
"main": "index.html",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "lite-server",
},
"author": "Sateesh",
"license": "ISC",
"dependencies": {
"lite-server": "^2.5.4"
}
}
After this run this on terminal
npm start
I think this should help :)
I had a similar issue,yarn start worked for
Given the following excerpt from package.json:
{
"name": "foo",
"version": "0.0.1",
"description": "Foo",
"main": "bin/index.js",
"bin": "bin/index-cli.js",
"private": true,
"scripts": {
"install": "tsc",
"test": "echo \"Error: no test specified\" && exit 1"
},
...
}
npm install fails with:
npm ERR! enoent ENOENT: no such file or directory, chmod '/home/mk/work/my-project/node_modules/foo/bin/index-cli.js'
Which is, because the install script (tsc - typescript compiler), which generates bin/index-cli.js from src/index-cli.ts is not executed before npm tries to create the sym link.
Question: What is the right way to have a bin, which is generated by an install script?
I am new to react js and I have installed the dependencies for the application. Below is my package file:
package.json
{
"name": "reactapp",
"version": "0.0.0",
"description": "learn and test",
"main": "index.js",
"scripts": {
"start": "webpack-dev-server --hot"
},
"author": "john doe",
"license": "BSD-2-Clause",
"dependencies": {
"webpack": "~1.13.3",
"webpack-dev-server": "~1.16.2",
"react": "~15.3.2",
"react-dom": "~15.3.2"
},
"devDependencies": {}
}
It throws the error:
npm ERR! weird error 1
npm WARN This failure might be due to the use of legacy binary "node"
npm WARN For further explanations, please read
/usr/share/doc/nodejs/README.Debian
npm ERR! not ok code 0
But, in the terminal while it doesn't show up anything when in scripts it is
"test": "echo \"Error: no test specified\" && exit 1"
You need to use the sudo command while installing nodejs-legacy.
Executing sudo apt-get install nodejs-legacy from your command line/shell will resolve the issue.
