'Cannot npm run dev. cross-env: not found . I have put path. however it says not find

My project is not able to do npm run dev. cross-env: not found .error happened. I changed my package.json. below

    "private": true,
    "scripts": {
        "dev": "npm run development",
        "development": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
        "watch": "npm run development -- --watch",
        "watch-poll": "npm run watch -- --watch-poll",
        "hot": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
        "prod": "npm run production",
        "production": "node node_modules/cross-env/dist/bin/cross-env.js  NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"

I have put path. However it still says "not found".

$ sudo npm run dev

@ dev /var/www/bb
npm run development


> @ development /var/www/bb
> node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

If you want to use cross-env or any other module, please make sure it's there in package.json and you have run yarn install or npm install in that directory containing the package.json. If the problem still persists, try deleting the node_modules folder in this directory and try running yarn install or npm install again.
