This is the error I get when I give command "npm start".
My package.JSON file has the following contents:

}
}
There is a comma missing after this line "test": "echo \"Error: no test specified\" && exit 1"
Also, if that doesn't work, try renaming your package.json to package.json.old and re-doing npm init. It solved my problem. I was going crazy for hours trying to figure it out.

You have to add a new key in your scripts key
"scripts": {
"dev": "npx tailwindcss -i ./css/tailwind.css -o ./dist/style.css --watch",
"test": "echo \"Error: no test specified\" && exit 1"
},
./css/tailwind.css is your sour; change the name according.ly
./dist/style.css is your dist path/filename
--watch is to keep running and watch when you change something in your code
when I try the command npm install I have this

Probably your file association is other than JavaScript like JavaScript react or any other.
Check your package.json settings file to have Item:javascript Value:javascript as default extension (*) on Files:Associations.
package.json->file->preferences->settings->Files:Associations
Item:javascript Value:javascript
Hope it works!
Today, I'm coding a few npm packages and a few things that need to be prepared repeatedly.
So I wanted to code a CLI to get those things done quickly.
Here is the src/cli.js code:
export function cli(args){
console.log(args);
}
Here is the package.json code:
{
"name": "my-project",
"version": "1.0.0",
"description": "A CLI to bootstrap new project",
"main": "src/index.js",
"bin": {
"#kensoni/my-project": "bin/my-project",
"my-project": "bin/my-project"
},
"publishConfig": {
"access": "public"
},
"keywords": [
"cli"
],
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "Ken Nguyen",
"license": "MIT",
"dependencies": {
"arg": "^5.0.0",
"esm": "^3.2.25",
"inquirer": "^8.1.1"
}
}
Here is the bin/my-project code:
#!/usr/bin/env/ node
require = require('esm')(module /*, options*/);
require('../src/cli').cli(process.argv);
After I execute the command npm link and open a new cmd type my-project, I get the following message:
'"/"' is not recognized as an internal or external command,
operable program or batch file.
I am using these versions:
node: 14.17.1
npm: 7.18.1
Any ideas how it might work.
Thanks in advance.
Remove "/" after env
#!/usr/bin/env node
//...
Edit:
I'm asking how to install it from GitHub, not npm, that the question.
In case you want to know why: I'm working on some private projects and don't what t publish the code. This leads to the code being in a private repository, not published on npm.
Original post:
Trying to install a module from GitHub (it is in typescript, thus I need a compilation script [postinstall]). It seems to fail because one of the module dependencies is also on GitHub, and that postinstall script is not waited on by the current postinstall script.
Old GitHub issue that sounds related: https://github.com/npm/npm/issues/5001
Yes, like the issue, I also use the same dependency in the main project as the module does.

It's not a good practice to publish unbuilt packages. I recommend changing the postinstall script into a prepare script so it builds the package before publishing it.

This would fix your issue.
The package.json is:
{
"scripts": {
"test": "find ./js/tests -name '*.test.js' | xargs mocha -R spec",
"start": "node ./scores.js",
"run": "node ./scores.js"
},
"dependencies": {
"aws-sdk": "^2.734.0",
"body-parser": "^1.19.0",
..
"dotenv": "^8.2.0"
},
"name": "scores",
"version": "1.0.0",
"main": "",
"repository": {
"type": "git",
"url": "something"
}
}
npm install has been done and the package-lock.json created. Why are either npm run or npm run-script working?
$npm run-script ./scores.js

I have identically structured package.json and scripts in other sibling directories that do work e.g. the following works via cd ../keys_server; npm run keys_server
$cat ../keys_server/package.json
{
"scripts": {
"test": "find ./js/tests -name '*.test.js' | xargs mocha -R spec",
"keys_server": "node ./keys_server.js",
"start": "node ./keys_server.js"
},
"dependencies": {
"aws-sdk": "^2.734.0",
"body-parser": "^1.19.0",
"express": "^4.17.1",
..
"dotenv": "^8.2.0"
},
"name": "keys_server",
"version": "1.0.0",
"main": "keys_server.js",
"repository": {
"type": "git",
"url": "something"
},
Update #pkumar noticed that the main entry was left empty. I now updated it to :
"main": "scores.js",
and then tried both
npm run-script ./scores.js and npm run scores and npm run scores.js. However none of them work:
$npm run scores
npm ERR! missing script: scores
The 'main' field is empty in package.json. try adding scores.js there and see if it works
The 'main' field is supposed to be the entry point of the server: https://docs.npmjs.com/cli/v7/configuring-npm/package-json
EDIT: The actual reason it's not working is because "scores" had not been defined under the scripts section. After adding that definition it should work
"scripts": {
..
"scores": "node ./scores.js"
}
