 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

What is the version of node.js installed on your computer? – Divulsion

Answer 1

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

Answer 2

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"
  }

Answer 3

I change my nodeJS engine version to v14 like this and it worked :

  "engines": {
    "node": "14.x",
    "npm": "6.x"
  },

Source : the recommanded version is 12 at least, but 14 recommanded https://strapi.io/documentation/developer-docs/latest/setup-deployment-guides/installation/cli.html#step-1-make-sure-requirements-are-met
