npm init doesn't create package.json - npm

Question

I am new to ReactJS, I was following one of the tutorials in "TutorialsPoint".
In Step 2: After the folder is created we need to open it and create empty package.json file inside by running npm init from the command prompt and follow the instructions.
C:\Users\username\Desktop\reactApp>npm init
By running the above command I am unable to create and package.json
Only this thing is coming up after running init.
In Step 4: it asks to add dependencies and plugins
In Step 5: it asks to open the package.json and delete "test": "echo \"Error: no test specified\" && exit 1" inside "scripts" object.
Now how can I open package.json, if I was not been created from the beginning?

Answer 1

Complete the npm init prompts
The command npm init "will ask you a bunch of questions, and then write a package.json for you."
The first prompt, as shown in your screen capture, asks you to enter a package name. You can just hit Enter to skip through the prompts and accept the default values if you are unsure of what information to provide.
You can also use -y/--yes to skip the questionnaire altogether. For example, npm init -y. (Note: -f/--force also work.)
Each prompt corresponds to a field in the package.json file. Consequently, you can construct this file yourself or copy and modify an existing one from another project.

Answer 2

A package.json must have:
A name all lowercase one word, no spaces, dashes and underscores allowed;
A version in the form of x.x.x;
There are two ways to create a empty package.json file:
Run a CLI questionnaire to create a package.json with values that you supply. For that run the command:
npm init
Create a default package.json. For that you just need to run the same command but with the --yes or -y flag.
npm init --yes
and it will create the package.json file in the dir where you run the command and will display the code shown bellow:
{
"name": "reactApp",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC"
}

Answer 3

Generally, it is not required for installing packages. If you don't use npm init for the folders, all the package can work without it.
Also for solving this problem, you should use
npm init --yes
when used with --yes then it is available the .json file in the directory. Also, the information on the .json file is dependent on the package that you had installed.

Answer 4

I am new on npm. I got confused just like you when i was trying to follow the npm tutorial.
You just need to press the 'Enter' key on your keyboard after your step2.
When you press 'Enter', you give default value to it. So it's gonna generate the json file based on its default information... hope it helps.

Answer 5

I had same problem in my project directory. when i run npm init it gives Error that package.json not found, complete log found in something like this " c:/user/node_modules/...".
This is because it overwrites the existing package.json file or the file path is not correct.
Also Admin permission is not granted to create such file. so try VS Code or IDE you all use to run as Administrator.
So, i put my project in the other Drive **(E: drive) and then run npm init** it works fine and create package.json file.

I fall onto this problem, when I typed npm init and press enter:
D:\React\booking>npm init
npm ERR! code MODULE_NOT_FOUND
npm ERR! Cannot find module './util.js'

Here is the answer that helps a lot about this problem
Follow these steps, closely:
http://nodejs.org/download/ download the 64 bits version, 32 is for hipsters
Install it anywhere you want, by default: C:\Program Files\nodejs
Control Panel -> System -> Advanced system settings -> Environment Variables
Select PATH and choose to edit it.
If the PATH variable is empty, change it to this: C:\Users{YOUR USERNAME HERE}\AppData\Roaming\npm;C:\Program Files\nodejs
If the PATH variable already contains C:\Users{YOUR USERNAME HERE}\AppData\Roaming\npm, append the following right after: ;C:\Program Files\nodejs
If the PATH variable contains information, but nothing regarding npm, append this to the end of the PATH: ;C:\Users{YOUR USERNAME HERE}\AppData\Roaming\npm;C:\Program Files\nodejs
Now that the PATH variable is set correctly, you will still encounter errors. Manually go into the AppData directory and you will find that there is no npm directory inside Roaming. Manually create this directory.
Re-start the command prompt and npm will now work.
