gulp-ts | TypeScript compiler plugin for Gulp | Frontend Framework library

Hello I have a project that uses gulp and the gulpfile.js suddenly has stop working despite not being changed.

my output reads

cmd.exe /c gulp --tasks-simple The system cannot find the path specified.

So I have been stuck on this problem for longer than i'd care to admit but as a Angular newbie I am completely baffled.

So I am following some online tutorials in order to implement Gulp into an application I am working on and whenever I run the Gulp tasks I get an error in Chrome which states:

"[Violation] Avoid using document.write().(anonymous) @ (index):13"

and:

//\/script>".replace("HOST", location.hostname)); //]]>

I am even more confused as the index.html doesn't actually contain a document.write reference before execution. Also despite mostly following a tutorial when integrating Gulp I cannot seem to have the CSS background changes reflected on screen, could this be related to the previously mentioned error?

When I build, the first error in the list is:

There are dozens of other errors after that but Im assuming most are due to this first issue.

Here is the package.json and typings.json

I have a simple Hapi.js Node API. Since I have used TypeScript to write the API, I wrote Gulp task for transpiling the code. My API works fine if I run it directly in my main machine but I get the following error when I try to run it inside Docker:
