Tried to download from here -https://github.com/sass/node-sass/releases/tag/v4.5.0
and install locally but getting at the logs -

9 verbose stack Error: 404 Not Found: darwin-x64-51_binding.node@latest

How can I solve the Node Sass error and finaly get back to development??
Its very frustrating!!

Hey, did you already fixed this problem? I met it just now, can you share you solution with me? thank you!

I solved it by uninstalling the node 8 and installing node 6

Then I solved it by installing 8 and getting the ionic 3 with angular 5, but you’ll need to change the http to httpclient and pay attention to observables …
