I'm trying to follow an online course of laravel with laragon. I need to run the command npm install, but it marks an error and I don't know how to fix it.

I tried to modify the path but that did not work

C:\laragon\www\social>npm install
"CALL "C:\laragon\nodejs\\node.exe" "C:\laragon\nodejs\\node_modules\npm\bin\npm-cli.js" prefix -g" no se reconoce como un comando interno o externo,
programa o archivo por lotes ejecutable.

> [email protected] install C:\laragon\www\social\node_modules\node-sass
> node scripts/install.js

I hope with this command works correctly but it marks these errors, help me, please

P.S: I work on a laptop with windows 7 home premium.

  1. $ npm cache clean --force
  2. delete node_modules by $ rm -rf node_modules
  3. $ npm install

And then start it again with $ npm start

I think you should install manually ajv package or update it to version 6.0 if you already have a lower version

npm i ajv

i had a similar issue. after updating it works fine. Try doing same for other errors also.
