I deleted the node modules and package.json.lock file in my client side MERN Stack project folder and tried reinstalling the node modules by typing "npm install" command in the terminal. but it's showing me an error. 1. I have tried clearing cache using "npm cache clean --force".
2. I have tried reinstalling npm using "npm install -g npm".
3. I have tried updating the npm using "npm install -g npm#latest".
But nothing works. Please help me resolve this issue. below are my package.json file and the error in my terminal while installing node modules.
i was expecting that node modules will be reinstalled with all the dependencies mentioned in my package.json file.
NPM changed the way of resolving peer dependencies in v7, but this new way does not allow conflicting dependencies in the dependency tree. The simplest way to solve this would be to use the --legacy-peer-deps option to use the old way of resolving dependencies.
The hard(but better) way to solve it would be to spend some time to update the dependencies in a way that there is no conflicting dependency.

I recently updated my Node and now whenever I try to update the node modules of this project I get errors. This is the only project that gives issues with it, all the other once are fine.
I tried removing the node module's and the react-countdown-clock in the package.json, I also tried copying the files to see if i could find the problem. But with everything I tried I still got the error's. So I was wondering if anyone has any advice for me how to fix it.
Execute below Commands
npm install -g npm-check-updates
ncu -u
npm install
npm start
windows 10
node v10.15.1
npm v6.8.0;
I:\>npx create-react-app newpomodoro
Creating a new React app in I:\newpomodoro.

Done.
I installed react globaly and loacaly as well but still it was giving me same error.
Can anyBody tell me whats going wrong.
Use this command:
npm cache clean --force
I am having this same problem with npm install --save --save-exact --loglevel error react react-dom react-scripts has failed. Mine then deletes node_modules and package.json. I have asked about this here: NPX create-react-app aborting installation after vulnerabilities found
I have already tried to use npm cache clean --force but this has not solved the problem. I have also tried installing different versions of node.js to no avail.
I ran into a similar issue. I don't know if you might have been in the same boat, but the cause was a space in my path name. I often save my projects on google file stream which has a space in the name ("G:/My Drive/..."). I tried creating the app in another directory and moving the folder which ended up working out.
The command npm clean --cache won't help.
If you are facing an abort installation error in react.
The abort installation error generated because of the older node version.
you should update your node package version.
To solve, run the following command and it will solve the abort installation error.
nvm install node 12.18.0
So, update your node package to the latest one. Once you've updated your node package then create your react app as follows:
npx create-react-app <your-app-name>
The abort installation error occurred because the outdated version of your node was not supporting the create-react-app command and deleted the node_modules and package.json file
Try this, please. It solved my error and hopefully, it'll solve your error too.
The issue was in node version just update it to latest version and it work's for me!

here is the solution which works for me, first of all, you should update all of your dependencies
then ran the command
npm cache clean --force
after that you can use
npx create-react-app
I just upgrade my npm to v5.3.0 and run into a problem: after I install/uninstall a module, npm would automatically clear my local modules that I manually put into my node_modules. These local modules are not included into package.json. This is really annoying. Please help, thanks.
The solution is similar to the question How To Specify Local Modules As NPM Package Dependencies. The command is "npm install [path-to-local-module] --save". The local modules will be copied into the node_modules folder and their dependencies will be added to package.json.
Im new to this all npm thing and I have a question about dependencies.
I started the React tutorial and I have been asked to run the following command:
npm install -g create-react-app
also, for a side project I also rn this following command in the same directory:
npm install react-chartjs-2 chart.js
And suddenly, my node_modules contains 800+ folders of packages.
So I found this site that tells you how many packages your package depends on and it showed me that I depend on only 100+ packages.
I know the meaning of npm install.
I find it really unexplainedable, I will appreaciate any help from your side.
Thank you very much.
install npm-remote-ls globally and check the dependencies of any package you want
npm install npm-remote-ls -g
checking react dependencies: npm-remote-ls react
I have cloned a repo that has Yeoman installed.
I installed node, as well as Yeoman npm i -g yo. When I run grunt I get an error stating:
Error: Cannot find module 'load-grunt-tasks'
Warning: Task "default" not found. Use --force to continue.
What else do I need to do to be able to run this repo successfully?
The first time, you have to run npm install.
This will install all the needed dependencies as described in the package.json
Subsequently, if anyone add a new dependency into this file, you will need to run npm install or npm update again.
Actually besides npm, you should also download bower dependencies.
So it's 2-step:
npm install
bower install
If you don't invoke bower application may launch, but later you may encounter problems such as the lack of libraries.
