Npm install build failed

Question

I've installed node-sass v4.12.0 but when I do an npm i, it uses the 4.9.4 for some reason. I don't know where it gets de 4.9.4 from, because in my package.json I use the 4.12.0.

My node-version: 12.3.1

Things I've tried:

• Clear the cache
• Deleted the node-modules
• Deleted package-lock
• Already tried an npm rebuild node-sass
• Start the project in a new folder.

Nothing worked so far

Answer 1

My problem was solved by installing nodeJs version 11.0.15. After I did this, my "npm install" works without a problem.

Answer 2

From the folder, it looks like the old version is a dependency from https://www.npmjs.com/package/@angular-devkit/build-angular, but I don't see an explicit mention of node-sass in the dependencies. If the sub-dependency is pinned to node-sass 4.9.4, the highest version of Node that will be compatible is Node 10 https://github.com/sass/node-sass#supported-nodejs-versions-vary-by-release-please-consult-the-releases-page-below-is-a-quick-guide-for-minimium-support
