Hi @hkirat,
I found following issue while running node for the first time in my mac m1 box.
**root ~/self_help/js_practice/assignments [master] $ npm install
npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path /Users/jee/self_help/js_practice/assignments/package.json
npm ERR! errno -2
npm ERR! enoent ENOENT: no such file or directory, open '/Users/jee/self_help/js_practice/assignments/package.json'
npm ERR! enoent This is related to npm not being able to find a file.

==> I was getting the above issue in my mac box and ran "npm init -y" to create package.json. Is it a right way to do that ?
==> But still I was facing some issue while running test. I think it was because I didnt have "jest" installed on my system.
==> Can u plz put some light on this issue ?
The error message you encountered indicates that npm install was run in a directory that does not contain a package.json file. The package.json file is crucial in Node.js projects as it defines the project's dependencies, scripts, and other configurations. Here's a breakdown of the issues and solutions:
Issue with package.json
When you run npm install in a Node.js project, npm looks for the package.json file to understand which packages to install. The error you received is because npm couldn't find this file in your current directory.
Solution: Initializing package.json
Running npm init -y is a correct approach to quickly create a default package.json file in your project directory. The -y flag will automatically fill in the default values without prompting you for input. After doing this, you can modify the package.json file as needed.
Issue with Running Tests (Jest)
If your project uses Jest for testing but Jest is not listed in your package.json file under devDependencies, you will encounter issues running tests.
Solution: Installing Jest
Install Jest: If Jest is not installed, you need to install it. You can do this by running:
npm install --save-dev jest
This command installs Jest and adds it to your devDependencies in package.json.
Configure Test Script: Ensure that your package.json has a test script configured to use Jest. This typically looks like:
"scripts": {
"test": "jest"
}
Running Tests: After Jest is installed and configured, you can run your tests using:
npm test
General Tips
Understand package.json: Familiarize yourself with the package.json file, as it's a core part of Node.js projects.
Local vs Global Installation: For tools like Jest, local installation (in your project's node_modules directory) is usually preferred over global installation. This ensures that everyone working on the project uses the same version of the tool.
Check Existing Configuration: If you're working on an existing project, check if there's already a package.json file and a defined workflow for setting up the project.
By following these steps, you should be able to resolve the issues you faced and successfully run tests in your Node.js project on your Mac M1 machine.
just use the correct directory, these errors are generally related to that. Also make sure to install jest package using npm
