Seems like you you should remove your vendor and node_modules directories and do the installs again because it would seem like something did not install properly. I would start with the node_modules.

Strange "Cannot find module 'shebang-command'" Error on npm run dev
Hi,
I just set up new Ubuntu 18.04 and cloned my previously working project from repo.
composer install, npm install all went fine
But during npm run dev I am getting this error:
> @ dev /var/www/html/myblog
> npm run development
> @ development /var/www/html/myblog
> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js
module.js:549
throw err;
^

In my other machine it is working perfectly fine.
Any suggestion on this?
Thanks!

your npm version (v3.5.2) seem quite outdated. May be can try to update your npm version first and rerun all npm install again

I even tried npm cache clean followed by npm install after removing node_modules. Only error I get is that fsevents is not insatalled. That should be fine becasue fsevents is for Mac OSX only.

But npm run dev still gives me same error.

Finally I figured this out.
Its because I don't have libpng-dev installed on my fresh installation of Ubuntu.
This is required by pngquant-bin, which is required by laravel-mix. This somehow disturbed the installation of shebang-command and laravel-mix.
Solution:
$sudo apt install ligpng-dev
And on laravel project
$ rm -rf node_modules
$ npm cache clear
$ npm install
$ npm run dev
Solved!
