I’m having some problems. Let me try to take you down the steps I took to get me in this situation. Yesterday, everything was working great! Then I did something… I don’t exactly know what I did, but I updated some file from 4.4.0 to 4.7.0… I think it was either Ionic, Cordova, or NPM related.

After updating I got an error saying that Angular CLI is not compatible with my version of Node. For some reason I decided to follow this tutorial to fix: https://github.com/angular/angular-cli/issues/10527 saying:

1. Download and save a local copy of the correct version of node-sass binary - win32-x64-64_binding.node. For example download it to the following location: C:\node-sass\win32-x64-64_binding.node
2. Provide reference to the full path of the node-sass binary file in the sass_binary_path npm configuration parameter (in the ~/.npmrc file): npm config set sass_binary_path <path to node-sass binary> For example, npm config set sass_binary_path C:\node-sass\win32-x64-64_binding.node
3. Run the npm install command again to install @angular/cli correctly.
4. Execute ng serve or npm start and your should be past the problem.

So I changed the node-sass path. I was still having some issues and realized that to fix I literally just had to download the latest version of NodeJS, which I ended up doing.

I then did npm install on a project I was working on, which then gave me a lovely error:

Failed at the node-sass@4.7.2 postinstall script.

I tried doing npm rebuild node-sass --force which did nothing, unfortunately.

At this point it must’ve been hour 10 of trying to figure out what the heck was going on, so out a fit of frustration I decided to do a Windows 10 recovery for the previous day. But no, I still have problems.

Here is the error report after doing npm install:

Binary found at C:node-sasswin32-x64-64_binding.node

Binary has a problem: { Error: Cannot find module 'C:node-sasswin32-x64-64_binding.node'
