Make sure there is no other configuration file (beside package.json) which would still reference the old GitHub repository URL. Check your git config -l.

After your git init, make sure to make at least one new commit, and push to the corresponding new GitHub repository.

You need to install gh-pages globally by adding "-g":

npm install -g gh-pages

and then

npm run deploy

Docs: https://docs.npmjs.com/downloading-and-installing-packages-globally

Try setting "homepage": "http://alisliim.github.io/Eurikso-Mobility-Academy"

because "homepage" means site URL and not repository URL.

from GitHub Docs:

The source files for a project site are stored in the same repository as their project. Unless you're using a custom domain, project sites are available at http(s)://<user>.github.io/<repository> or http(s)://<organization>.github.io/<repository>.

Use version 2.0.1 instead of 2.2.0 for gh-pages

running "gh-pages -d public" hangs on "pushing" per node debug #324

I found out that you don't need the build script or the pre-deploy script. they are unnecessary to be used, since my website is static, I can navigate directly to the build folder and it will work fine.

I have modified the config.json file to be as in the following

{
    "name": "AmrAhmed",
    "version": "1.0.0",
    "description": "",
    "main": "truffle.js",
    "directories": {
        "test": "test"
    },
    "scripts": {
        "dev": "lite-server",
        "test": "echo \"Error: no test specified\" && exit 1",
        "deploy": "gh-pages -d src"
    },
    "author": "",
    "license": "ISC",
    "devDependencies": {
        "gh-pages": "^3.0.0",
        "lite-server": "^2.5.4"
    }
}

run the command npm run build

and it will be deployed to Github pages.

So I run this command npm install --save gh-pages

like below

After that I run the command npm run deploy

My code published successfully like below.
