You are using node version 16.13.1, I have found the solution to the decreasing the version e get the node-v14.19.2

I cannot run any project because of gyp error. How can I fix this: npm ERR! gyp verb cli

Whenever I run my code I always get the same error. I uninstall node and npm and reinstall. But now there is no "node_modules" and I get the same error. How can I fix it?

There isn't node-sass and node-gyp. When I tried to install them I also got the same error. I cannot install anything.

I solved this problem by changing the node version to 14.15.1

Do not use node-sass anymore. Remove 'node-sass' in package.json. pls use 'dart-sass'.
https://www.npmjs.com/package/dart-sass (dart-sass is default now)

Please don't waste your time running the suggested command by others.
Please uninstall node.js and use the Node v14.x.
It will solve it automatically.

I got the same error and did this:
1. npm install node-sass
2. npm install
3. npm ci
4. ng serve --open (to launch the project ).

With most of the operating systems removing python2 this is a common issue for most projects. It definitely affected 4/5 of my recent projects after upgrading to current Linux/Debian Stable which removed python2.
The solution is for system to start using python3 and in order to do that you need to..
Solution/Solved is:
node-sass is actually at fault. Python2 is required until version 6.0.0. Normally you would upgrade to latest 7.0.3 but node-sass is currently obsolete, so we will swap to sass project.
yarn remove node-sass
yarn add sass
I've given more details on reasoning why here, or alternative dart-sass if you use "render() and renderSync() functions".:
Solved-ERR!gyp-info-using-node-gyp-3.8.0-gyp-verb-which-failed-Error-not-found-python2
Affected:
node.js /react web apps
Elixir/Phoenix assets
Android apps
Vue.js projects

The following solution works for me.
Try:
npm cache clean --force
npm uninstall node-sass
Uninstall node modules from your project
npm i sass --save

!important
i run into the same issue. ANd What I recomend to you is to install nvm to control your node version instead of unistalling the current version causing other problems with the existent projects.
NVM Installation Guide
https://www.geeksforgeeks.org/how-to-install-and-use-nvm-on-windows/
or
https://tecadmin.net/install-nvm-macos-with-homebrew/
After installation
After you are sure that you'd installed nvm successfully you can do:
nvm --version to check if nvm is successfully installed
nvm install [desired node version] ex.: nvm install 14.0.0
nvm list to check all node versions installed
nvm use [desired version] to change between node version ex.: nvm use 14.0.0
Conclusion
As I mention above, instead of unistalling your node versions you can install different versions of node and changing between then avoid future errors.
Be Happy even with bugs

I think you are using Windows for development. Some node.js modules required to build locally on a machine. so, that why it needs python version 2.x and other tools.
windows-build-tools package install required tools to build module locally. Go ahead and install this package and after installing it then try again running the command npm install command

gulp-sass error when installing

I have an error that gets thrown only when I try to install gulp-sass. I have tried installing other modules, (like gulp-livereload) and they work fine. Using npm version 6.0.0. Here is the package.json section that is requiring it:
"devDependencies": {
"gulp": "^3.9.0",
"gulp-autoprefixer": "^3.0.2",
"gulp-imagemin": "^2.3.0",
"gulp-livereload": "^3.8.0",
"gulp-sass": "^3.0.0",
"gulp-sourcemaps": "^1.5.2",
"gulp-uglifyjs": "^0.6.2",
"imagemin-pngquant": "^4.2.0"
}
The only one here that throws errors is gulp-sass. This is the error:

Turns out this wasn't a permission problem. All I had to do was add the flag --unsafe-perm=true. I suppose it is a problem with the gulp-sass postinstaller itself, judging from this github post. Thanks vishwa for pointing out the permission denied error, I would have never found that post without it. ;)
