Angular 5.0.3 - error TS2304: Cannot find name

I am trying to leverage golden-layout docking library. I have everything installed for my angular project but I am hitting an error that I cannot seem to get around.

webpack: Failed to compile.

I saw other another post and it is blank with no answers. When I originally got this error I did some research. I realized there was a typings problem. I went directly to the module files, and I could see the errors in the index.d.ts file. JQuery reference could not be found. So I googled around on how to fix that. The solution was to run npm install @typings/jquery. This solved my errors in the file. However, I am still getting the errors from cli when I try to run ng serve even though the errors are fixed in the index.d.ts file. I am sort of at a loss on how to move forward here.

Is there a way to just use the javascript file in angular instead of trying to use the module? Here is a plunker of it working with angular. I can see that they are just adding the script file directly to the index.html file. I have added the script file to the angular-cli.json file and it does not fix the problem. Angular still tries to use the module and hence the typing file. Any ideas or potential solutions? I feel like there is a cache somewhere that needs to be reset because I fixed the @typings error.
