I installed node.js because I needed a way for storing my javascript variables into a mysql database (I use phpmyadmin).
I'm getting this error and I just don't now what to do with it:
C:\Users\Robin> npm install mysql
C:\Users\Robin
`-- mysql#2.13.0
npm WARN enoent ENOENT: no such file or directory, open 'C:\Users\Robin\package.json'
npm WARN Robin No description
npm WARN Robin No repository field.
npm WARN Robin No README data
npm WARN Robin No license field.
I also typed another command (can't remember which one) and it gave me a list of what looks like usernames and email-accounts.
I have no idea which steps I need to take for succesfully installing node.js and make it work. I checked youtube video's and stuff but there like worthless.
So my question from scrath is: I installed node.js, how to make it work?
Kind regards from the Netherlands
Well, I may get your problem . Then i searched and found some valuable steps for you from the internet .
Create a new project: mkdir mysql-test && cd mysql-test.
Create a package.json file: npm init -y.
Install the mysql module: npm install mysql.
Create an app.js file and copy in the snippet below (editing the placeholders as appropriate).
Run the file: node app.js. Observe a “Connected!” message
Here is the Url where i got these information :https://www.sitepoint.com/using-node-mysql-javascript-client/
Best of luck .
You need have package.json file.
Do first:
npm init
Then you will have package.json. Now you can do:
npm install package
Or
npm install package --save (for save dependencies in package.json)
EDIT:
Iam trying do npm intall in a void folder in my coputer:
diego.martin#csa-188:~/Proyectos/pruebas/prueba$ npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.
See `npm help json` for definitive documentation on these fields
and exactly what they do.
Use `npm install <pkg> --save` afterwards to install a package and
save it as a dependency in the package.json file.
Press ^C at any time to quit.

my npm was working perfectly fine, today I wanted to install a package and I got a lot of npm ERR! messages.
Then I saw that npm was creating package.json, package-lock.json, and a node_modules folder in the directory I was installing the packages in.
Shouldn't these files and folders be in /bin/ somewhere?
Then after I reinstalled some packages npm ls works but after some time it outputs:
├── #babel/code-frame#7.18.6 extraneous
├── #babel/helper-validator-identifier#7.19.1 extraneous
├── #babel/highlight#7.18.6 extraneous
├── #jridgewell/gen-mapping#0.3.2 extraneous
├── #jridgewell/resolve-uri#3.1.0 extraneous
├── #jridgewell/set-array#1.1.2 extraneous
But not just these, there are hundreds.
I just uninstalled Node and npm and re-downloaded it again.
But now when I tried to install a package it created a node_modules folder, package.json and package-lock.json in my home directory.
These files and the folder is not supposed be there, right?
Thank you!

I am getting this issue in command prompt. i have tried these commands sudo npm i -g npm, npm i -g npm-upgrade, by running in command prompt but it's not working for me. How to resolve this issue.can anyone please help me.
I'm assuming you don't have it installed. (Even in the case you have it, it can be easily updated by this method).
If you have a Mac, install Brew and if you are on Windows, Chocolatey and then follow their respective commands to install/update npm. They will mostly take care of all the necessities to install/download anything.
The command will be mostly:
brew/chocolatey install npm
if this a windows system you need to run cmd with administrator rights and try it.
Download and install nodejs
Also add nodejs path and npm in roaming folder paths to env variables
Did all the command on command line
from installing the npm globally npm install -g create-react-app along with following codes:
npx create-react-app <myprojectname>
and also cleared the npm cache but it always get stuck on the line in the image showing the following error. Along with the error:

Here is what i found form the getting started page of create react app.
If you've previously installed create-react-app globally via
npm install -g create-react-app,
we recommend you uninstall the package using
npm uninstall -g create-react-app
to ensure that npx always uses the latest version.
npx create-react-app my-app
cd my-app
npm start
But always ensure that you have an existing folder before using npx.
So I have a large React app created and set up with Create React App. Recently we started using Storybook to work on and create components. Its been great. However, we keep getting this weird webpack issue when we try to run or build the app. Here is the console log out:
> react-scripts start
There might be a problem with the project dependency tree.
It is likely not a bug in Create React App, but something you need to fix locally.
The react-scripts package provided by Create React App requires a dependency:
"webpack": "4.41.2"
Don't try to install it manually: your package manager does it automatically.
However, a different version of webpack was detected higher up in the tree:
/Users/alexanderkaran/Documents/ClimateClever/cc_school_web/node_modules/webpack (version: 4.41.5)
Manually installing incompatible versions is known to cause hard-to-debug issues.
If you would prefer to ignore this check, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That will permanently disable this message but you might encounter other issues.
To fix the dependency tree, try following the steps below in the exact order:
1. Delete package-lock.json (not package.json!) and/or yarn.lock in your project folder.
2. Delete node_modules in your project folder.
3. Remove "webpack" from dependencies and/or devDependencies in the package.json file in your project folder.
4. Run npm install or yarn, depending on the package manager you use.
In most cases, this should be enough to fix the problem.
If this has not helped, there are a few other things you can try:
5. If you used npm, install yarn (http://yarnpkg.com/) and repeat the above steps with it instead.
This may help because npm has known issues with package hoisting which may get resolved in future versions.
6. Check if /Users/alexanderkaran/Documents/ClimateClever/cc_school_web/node_modules/webpack is outside your project directory.
For example, you might have accidentally installed something in your home folder.
7. Try running npm ls webpack in your project folder.
This will tell you which other package (apart from the expected react-scripts) installed webpack.
If nothing else helps, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That would permanently disable this preflight check in case you want to proceed anyway.
P.S. We know this message is long but please read the steps above :-) We hope you find them helpful!

I know what your thinking you must have installed webpack, well I didn't. When I run:
npm ls webpack
I get this log out:

So the issue seems to be to do with storybook. If I uninstall all npm modules and remove storybook, then re-add both everything works again but eventually, it breaks.
Does anyone have a fix for this? Or am I missing something?
Looks like this an issue with the version of Webpack Create React App uses being a few steps behind the version Storybook uses sometimes.
There is no fix, but there are some workarounds.
You can find more info on the issue here:
https://github.com/storybookjs/storybook/issues/6505
One workaround is to add SKIP_PREFLIGHT_CHECK=true to a .env file in your project.
This can cause issue though.
Another workaround is to keep using a version of storybook and create react app that works with each other and doesn't cause these issues. So do not just upgrade storybook straight if it contains a Webpack version bump.

This line should be the hint. Your npm has a dash before it (i.e: -npm). Add a space between the - and npm in your configuration.
