Further technical details

Running a Windows 10 VM in Azure. Located this issue which indicated to update the gulp-sass version to 3.1.0. When I did a search of the solution, “gulp-sass” was only in the readme. But I did notice that npm install node-sass did result in a couple warnings. Namely that it could not find c:\repos\PartsUnlimited\package.json.

c:\repos\PartsUnlimited>npm install
npm WARN saveError ENOENT: no such file or directory, open 'c:\repos\PartsUnlimited\package.json'
npm WARN enoent ENOENT: no such file or directory, open 'c:\repos\PartsUnlimited\package.json'
npm WARN PartsUnlimited No description
npm WARN PartsUnlimited No repository field.
npm WARN PartsUnlimited No README data
npm WARN PartsUnlimited No license field.

up to date in 1.344s

c:\repos\PartsUnlimited>npm --version
5.6.0

c:\repos\PartsUnlimited>node --version
v8.9.4

I did also go through the git clean -fdx step as well to no avail.

That worked for me:

npm --depth 9999 update
npm rebuild node-sass

With “yarn add node-sass” worked for me
