I can't install laravel-elixir in my Homestead VM

Question

I am following a tutorial and I see they install laravel-elixir with sudo npm install. However when I try to do the same I got this error:

vagrant@homestead:~/Projects/dmca-app$ sudo npm install

it looks like a admin problem but I am using sudo.(OS X Yosemite) Any ideas? please.

Answer 1

Yes, I did Michal. I noticed my package.json looked like that

{ "private": true, "devDependencies": { "gulp": "^3.8.8", "laravel-elixir": "*" } }

I don't know why I had the first line but I checked others laravel installation and I can't see this line. I removed the first line

{ "devDependencies": { "gulp": "^3.8.8", "laravel-elixir": "*" } }

after that I ran in the terminal

npm cache clean

and then

npm install

and I could install gulp and laravel-elixir. Even I posted this answer in https://laracasts.com/discuss/channels/general-discussion/npm-install-error-inside-homestead-machine?page=1#reply-63764 and somebody told me that it worked for him.
