When I run npm run build I get this error?

I am pretty new to this and pretty lost as well. I believe I switched up a lot of things which has me facing this problem at the moment. Ultimately, I am just trying to npm run build my React.js project so I could deploy it. But I run npm run build and I see this error:
my-blog git:(main) ✗ npm run build
npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path /Users/rondon/code/my-blog/package.json
npm ERR! errno -2
npm ERR! enoent ENOENT: no such file or directory, open '/Users/rondon/code/my-blog/package.json'
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent
npm ERR! A complete log of this run can be found in:
npm ERR! /Users/rondon/.npm/_logs/2022-01-22T05_37_12_010Z-debug.log
What I understood from this is that I need to make a package.json file so I did that in my "my-blog" directory by running npm init. Cool, I do that and now I have a new package.json file in "my-blog" and I manually put in a "build": "react-scripts build" so I can run npm run build without getting an error saying I am missing a build script. This is how that package.json file looks now:
{
"name": "my-blog",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"build": "react-scripts build"
},
"repository": {
"type": "git",
"url": "git+https://github.com/rmera1026/my-blog.git"
},
"author": "",
"license": "ISC",
"bugs": {
"url": "https://github.com/rmera1026/my-blog/issues"
},
"homepage": "https://github.com/rmera1026/my-blog#readme"
}
I npm run build again and now get this:
my-blog git:(main) ✗ npm run build
> my-blog#1.0.0 build
> react-scripts build
sh: react-scripts: command not found
Lastly, I think I am having this problem because of how my file might be set up as well so here are how things are looking.

Your my-blog project has 2 directories. One is api, another one is client.
You have to build in your client directory, but you're outside of it. Change your directory to client and run npm run build
cd client && npm run build

tailwind doesn't with npm run dev

I got a task to do which is to create some forms with tailwindcss but When I try to launch : npm run build, it does't work. Could you help me?
npm ERR! code ELIFECYCLE
npm ERR! errno 9
npm ERR! widgets#1.0.0 dev: `tailwind build css/tailwind.css -o build/css/tailwind.css`

this is my package.json
{
"name": "widgets",
"version": "1.0.0",
"main": "index.js",
"scripts": {
"dev": "tailwind build style.css -o /css/tailwind.css"
},

"devDependencies": {
"autoprefixer": "^10.4.2",
"postcss": "^8.4.5",
"tailwindcss": "^3.0.15"
},
"dependencies": {},
"description": ""
}

You need to install Tailwind CLI in order to execute tailwind commands:
# Using NPM?
npm install -D tailwindcss
# Using yarn?
yarn add tailwindcss -D
Also, it helps to check the error log (as mentioned in the message printed to your terminal) to find out a full stack trace of the error.

I have successfully run npm login. Then I am executing npm publish.
I have cloned this repo from GitHub and publishing to the npm. It's actually about creating npx card of your own name, like npx username. I am doing the same.
I have tried giving it a different package-name but couldn't make it. So, Could someone please tell me what I am doing wrong? Here is the package.json file.

Update: I believe its caused from issues from the .npmrc in your home folder. Messing with the $HOME variable also seems to make it fail. Removing that file, and logging back into npm seems to fix the issue.
Beyond the answer though, Suraj Oberai your question is very well worded with all the necessary information, I don't think you deserve your downvotes.
I've published many npm packages, but this was the first time I had come across this issue myself. It was very strange as there was almost no difference between this one and previous packages I've published. I had to track down the issue by taking one of my working packages and (many useless publishes later) slowly convert it into my attempt that was causing the error, only to get to the point where literally nothing different between the projects. Nothing except the HOME Env variable of the shell.
This is definitely a bug with npm. It seems like the error above is the default error, so its possible my change might not solve this issue for you.

The publishConfig URL might be wrong.
Can you try adding the publishConfig option in package.json:
"publishConfig": {
"registry":"https://npm.pkg.github.com"
},

It worked for with this other registry (maybe they updated it?):
"publishConfig": {
"registry": "https://registry.npmjs.org/"
}

GitHub NPM registry is used for private packages. The package name has to be scoped. "name": "suraj-ojha" won't work for GitHub. It needs to be something like #suraj/ojha or #bnb/bitandbang (since that's your GitHub username and repo name).
If you don't intend to publish a private package and want to publish it to the public, remove the publishConfig section in package.json so npm publish uses the default public registry.

My question is how can i prevent those errors and install node js and socket io correctly.

I suggest you install from NVM
after that. just do nvm install
to check. node -v inside your terminal

Install NodeJS from their website, then execute npm init within your project folder.
Afther that you can install dependencies from NPM.
Just read, what's on their websites under "getting started"...

I did npm init and this is my .json file
"name": "chat",
"version": "4.5.0",
"description": "IO",
"main": "app.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "Dan Vasii",
"license": "ISC",
"dependencies":
{
"socket.io" : "*",
"express" : "*"
}
}

Download the Windows installer from https://nodejs.org/en/ .
Run the installer (the .msi file you downloaded in the previous step.)
Follow the prompts in the installer (Accept the license agreement, click the NEXT button a bunch of times and accept the default installation settings).

Here is the solution for the above error.
Go to (nodejs) and Download NodeJs.
Install the NodeJs where you want in your PC
Now try to execute the command npm install
The error will be resolved. Any help needed please refer to this link
