Encountered error: A problem occurred while executing npm install && npm run dev - Vite - Laravel UI React

Question

Hi everyone, today I encountered a problem, when I installed laravel ui using react and passed to the npm install step an error occurred, so below you will find the error

npm ERR! A complete log of this run can be found in:

So above and below the error you will find my package.json

{
    "private": true,
    "scripts": {
        "dev": "vite",
        "build": "vite build"
    },
    "devDependencies": {
        "@popperjs/core": "^2.11.6",
        "@tailwindcss/forms": "^0.5.2",
        "@vitejs/plugin-react": "^2.2.0",
        "alpinejs": "^3.4.2",
        "autoprefixer": "^10.4.2",
        "axios": "^1.1.2",
        "bootstrap": "^5.2.3",
        "laravel-vite-plugin": "^0.7.2",
        "lodash": "^4.17.19",
        "postcss": "^8.4.6",
        "react": "^18.2.0",
        "react-dom": "^18.2.0",
        "sass": "^1.56.1",
        "tailwindcss": "^3.1.0",
        "vite": "^4.0.4"
    }
}

I tried reading the error and changing the vite version to 4.0.4 but nothing happened

You should be able to resolve this error using the following command:

npm install --legacy-peer-deps

This previous article details what --legacy-peer-deps is doing here.

In short, @vitejs/plugin-react (specifically the version you have as a development dependency 2.2.0) lists older versions of vite (vite@"^3.0.0") as one of its peer dependencies, but it is looking for a newer vite@"^4.0.4"# that is already installed ##. For reasons I can't fully explain (see the linked post or Google if you're curious), NPM is unable to resolve this peer dependency conflict in the same way that our more familiar regular and development dependencies typically resolve and . --legacy-peer-deps Work around this issue by bypassing automatic installation of peer dependencies.
