I am running my project on a Vagrant box, and I am running Laravel version 5.4.

Laravel Solutions

Solution 1 - Laravel

You need to make cross-env working globally instead of having it in the project.

run

$ sudo npm install --global cross-env

--- update ---

But, my advice is to avoid executing npm run ... on the guest homestead, because it is very slow and because there is no benefit in it.

No matter where you build the assets they are going to be executed in the browser. So you better install npm on your host computer and build the assets there.

Solution 2 - Laravel

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"
  },

........

}

Solution 3 - Laravel

Run:

npm install

Then try again.

Solution 4 - Laravel

If the solutions above didn't work, refresh node_modules using

rm -rf node_modules && npm install

this worked for me

Solution 5 - Laravel

There are couple of ways to solve this error.

Delete node_modules folder then do npm install again. if it doesn't solve then:
You can install as dev dependency by firing

> npm install --save-dev cross-env

if it doesn't solve then:

Install cross-env globally as npm install --g cross-env It will install it in \Users\Roaming\npm modules. Then I suggest you can close your shell and open it again & fire the command.

if it doesn't solve then:

in Package.json you can use like: > node node_modules/dist/bin/cross-env cross-env ...

Solution 6 - Laravel

The fast solution is to run:

npm clean-install

that sould fix the laravel mix error.

Solution 7 - Laravel

Sometimes deleting the /node_modules and running

npm install

will solve issues like this one.

Solution 8 - Laravel

You do need to check if cross-env module is installed. If not, run:

npm install cross-env

But you need it to be recognized as a "command". Patching the path as proposed by the accepted answer (or is it?) led me further, but still gave me an error.

The solution for me was to reload vagrant "vagrant reload --provision", and reset my ssh / putty session.

Solution 9 - Laravel

If you are just desperate of fixing this error like my case, just remove cross-env from you package.json and run laravel mix without it ..

Solution 10 - Laravel

I had to clone repository in a new folder. Wasn't able to identify which local file/setting caused the error.
