Laravel 5.4 ‘cross-env’ Is Not Recognized as an Internal or External Command

Question

I\'m trying to run npm run dev for Laravel Mix and I get this error:

> @ dev D:\\projects\\ptcs
> cross-env NODE_ENV=development webpack -         


        

Answer 1

Delete the node_modules folder

Then you should run the commands:

npm install --no-bin-links

npm run dev

It's worked on my Laravel 5.5 and Windows.

Answer 2

Simply try running npm install / yarn etc first before running npm start / yarn start as @only4 mentioned, if you see this problem, as it means your .env is not in sync with your package.json, i.e. you installed a package but not quite configured it or other way around

Answer 3

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

1) remove node_modules folder

2) run

npm install --global cross-env

3) remove "cross-env": "^5.0.1", from package.json file devDependencies section. Actually, you can skip this step and keep package.json intact. If you prefer.

4) run

npm install --no-bin-links

5) run

npm run dev

and see it working

P.S Tested on Windows 10 with Laravel-5.4

P.P.S Windows 10 with Laravel-5.6 does not have this problem, thus updating is an alternative solution.

Answer 4

You are getting the error because you might not have run the command npm install first.

i.e. First, run npm install and then npm run dev

Answer 5

Your error states that cross-env is not installed.

'cross-env' is not recognized as an internal or external command, operable program or batch file.

You just need to run

npm install cross-env

Answer 6

The following worked for Laravel 7.x (and should probably work for any other version as well given the nature of the issue).

npm uninstall --save-dev cross-env
npm install -g cross-env

Just moving cross-env from being a local devDependency to a globally available package.
