SyntaxError: Invalid or unexpected token when trying to run gulp - laravel

Question

I am new to gulp but on a existing laravel project I needed to add some css I was told to update the app.sass and then run gulp to compile it. I tried to follow a guide called Compiling Assets (Laravel Elixir) to compile the sass file but ran into problems. To get everything installed correctly I updated our bootstrap.sh file in the vagrant setup to include nodejs, npm, gulp and laravel-elixir. Once the changes were made I loaded the vagrant box and I verified that I have the following versions.
[vagrant#localhost project-css]$ gulp -v
[18:12:38] CLI version 1.4.0
[18:12:38] Local version 3.9.1
[vagrant#localhost project-css]$ npm -v
3.10.10
[vagrant#localhost project-css]$ node -v
v6.11.1
When I try to run gulp I get
/vagrant/src/project-css/node_modules/through2/node_modules/readable-stream/lib/_stream_readable.js:349
if (n <= 0 || state.length === 0 && state.end
SyntaxError: Invalid or unexpected token

The full project I'm working on is available on github at Rockefeller-css
Any suggestions would be appreciated.

Answer 1

I was able to resolve the issue on my own by adding the following to my bootstrap.sh file
rpm -ivh https://kojipkgs.fedoraproject.org//packages/http-parser/2.7.1/3.el7/x86_64/http-parser-2.7.1-3.el7.x86_64.rpm
yum install -y nodejs
Also after vagrant was finished loading and I was able to ssh into the box in a custom setup-vagrant.sh script that needed to be ran I was able to add the following command.
sudo npm install
Their was already a cd into the laravel project folder and their was a package.json file that existed. After that I was able to cd into the project folder and run gulp correctly.
