First check if cross-env module is installed. If not, run:
npm install cross-env
After that you need to go to the node_modules folder. Then find cross-env folder. Go inside and find cross-env.js.
In my case it was node_modules/cross-env/dist/bin/cross-env.js
You need to change path to cross-env.js in scripts section in your package.json file.
{
"private": true,
"scripts": {
"dev": "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": "node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"hot": "node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development webpack-dev-server --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
"production": "node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
},
........
}
If the above changes are already up to date then remove the directory
node_modules
and file
package-lock.json
update your node version to 8 and then
run command npm install and then npm run dev
