I have formatted my computer. Everything was working before. And now when I try to install it, that's what pops-up. I have tried reinstalling node.js but it didn't help. I don't know what should I do.

If your Node version is very recent, try downgrading. Stable version 14.16.1 worked.

Downgrading Node is one option but I don't like the idea of downgrading Node just because one package throws an error. In my opinion, it would be a better approach to find out which package is causing the error and then fix it.

The quick solution

In the line after npm ERR! code 1 you should be able to see npm ERR! path.... In my case the path indicates that there is a problem with the node-sass npm package:

npm ERR! code 1
npm ERR! path /home/gignu/GitHub/Movie-Subtitles/node_modules/node-sass
npm ERR! command failed

Now remove this npm package from package.json and see if the installation works. If it works you've found the culprit! In my case, all I had to do to fix it was to upgrade node-sass to the latest version.

// package.json with the outdated dependency

"node-sass": "^4.14.1",

// package.json with the updated dependency

"node-sass": "^7.0.1",

The slow solution

If the previous solution doesn't work for you I would go with @Andrew Fair's solution:

I took out the entire dependencies portion in my package.json file and just started working my way through installing one at a time.

To do this simply copy the whole dependencies section and devDependencies section from package.json and paste it into a text editor as a backup. Then delete all your dependencies and try adding back one dependency at a time. You can also add back several dependencies at a time if you have a lot of them. Each time run npm i and see if it throws an error. Once you've found out which dependency is causing the error try to upgrade that dependency to a newer version and then run npm i --force!

If that doesn't work, try replacing the bad npm package with another one or look on their GitHub repository for solutions.

try

npm cache clean --force

Delete node_modules and package-lock.json

npm i
2

I ran into this issue as well. After looking over my setup I saw nothing wrong and deleted the cache and deleted package-lock and still no success.

This was an older website and I tried using update/etc to no avail.

So I took out the entire dependecies portion in my package.json file and just started working my way through installing one at a time.

It works!

Apparently almost all of the versions were a major update behind which was to much for it to update.

I had faced the same issue after upgrading angular, So I tried multiple steps to resolve it. Some of the steps are mentioned below.

  1. try with deleting package-lock.json file and node_module folder then run
npm cache clean --force

and try npm i again to install packages if still not working check step 2

  1. Check nodeJs version and npm version if both versions are compatible. In my case, I was using node v14.15.0 and npm v8.1.6, so I uninstalled the npm with the below command and installed the node js again to make node and npm version in sync.
npm uninstall npm -g

and this works for me.

When I try to run npm install command in older project, I faced the same issues and I resolved it by updating the dependencies in package.json to latest version by following the steps:

  1. delete node_modules and package-lock.json

  2. install npm-check-updates globally, to update all packages to a new major version

    run npm install -g npm-check-updates

  3. run ncu -u to update dependencies in package.json to latest version

    note: you can use npm update, but npm update doesn't update to latest version

  4. run npm install

Maybe try yarn install. It works for me.

Try npm install --python=python2.7. It should work. EDIT: Alternatively, --python=path to your python executable

try cnpm,it works for me

npm install -g cnpm --registry=

cnpm install
