 Keep trying!

Oh, it seems that you encountered errors while installing dependencies in your project.
Don't give up, your project was created correctly.
Fix the issues mentionned in the installation errors and try to run the following command:

cd D:\E-LEARNING\React Js\projects\strapi-app && npm install

npm ERR! code 1
npm ERR! path D:\E-LEARNING\React Js\projects\strapi-app

Strapi apparently only supports Node v14 (current LTS). Switch to that version (NVM?) and try again.

I had the same problem when deploying to heroku. It worked by changing the npm version from >=6.0.0 to 6.14.9 in package.json:

  "engines": {
    "node": ">=10.16.0 <=14.x.x",
    "npm": "6.14.9"
  }
