Failed at the [email protected] postinstall script

Question

I just downloaded the latest version of node.js and I've been trying to do npm install on one of my projects but saying:

Failed at the [email protected] postinstall script.

I tried doing: npm rebuild node-sass --force which didn't do anything either.

The error log returns this:

and my npm and node versions are:

2 info using [email protected]
3 info using [email protected]

I've also tried completely deleting my node_modules folder and running npm install again but that didn't work.

One possible reason for this could be that before I updated node I followed this persons suggestion: https://github.com/angular/angular-cli/issues/10527

Where he says:

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 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.

I don't know if this is related.. I wouldn't think so since I've updated node, tried to force node-sass rebuild but I don't know.

Any ideas/advice on how to fix this? Thank you!
