Question

I am trying to use npm for a project I am working on in Homestead however I am getting some errors. I ran

npm run watch-poll

but I get this error

vagrant@homestead:~/code/testlaravel$ npm run watch-poll

> @ watch-poll /home/vagrant/code/testlaravel
> npm run watch -- --watch-poll


> @ watch /home/vagrant/code/testlaravel
> npm run development -- --watch "--watch-poll"

I'm new to npm and I have no idea what to do and I have not found anyone online with a similar problem.

npm version = 6.7.0

node version = v10.15.1

If you need it.

I would appreciate any help, also if you need anymore info about what i'm running and how things are set up let me know.

running

npm install

gives this result

Ok so I ran

sudo npm i -g cross-env

because I got a permissions error without the sudo bit, and it looks like it worked.

However I am getting a new error now

 ERROR  Failed to compile with 2 errors                                                                                                                                                  3:18:10 PM

 error  in ./resources/assets/sass/app.scss

 error  in ./resources/assets/sass/app.scss

I guess this is a problem with the my code/framework (i'm using laravel) but yes sudo npm i -g cross-env looks like it fixed it.

You have missing module cross-env. Run:

npm i -g cross-env

to install cross-env globally.
