"npm run dev" won’t work ( Solved )

 You are in the dev directory and the realizes "npm run dev "won't work and you scratching your head. I have been there as well. I even tried to force it hoping to get it through. Follow the steps bellow

• 1-Create file in your dev environment in your dev folder as in the screenshot bellow
• 2-I called the file .env and then enter the following line: SKIP_PREFLIGHT_CHECK =true; and the save 
• 
  

• 1- Launch PowerShell and cd to your dev folder

In my case it was just a practice project on my desktop

pwd to locate where I was and the

• cd Desktop
• cd to DevCage
• cd project
• and then "run npm start "and then wait
• A new tab will open with a localhost:3000 url and then your local environment will launch
• A few seconds later your will get a "compiled successfully message on PowerShell and you will be ready to go
