问题
I've been having issues with node-sass doing all manner of silliness during "npm install" including but not limited to :
- GNU c++ compiling something (likely itself)
- trying to run python2.7
- trying to run any other version of python
- trying to connect to github
and this was posing problems in a corporate context where I have to compile my project on Jenkins where NPM libraries must be pulled from a clone of npm registry on corporate servers and only the strict necessities of that specific project are available on the dockers so :
- no github
- no python
- no c++
and I'd decided I'd had enough of node-sass's shenanigans so I tried the suggested "dart-sass" since the notion seems to be that it is entirely angular-compatible and aims to solve most of the issues with node-sass : https://sass-lang.com/dart-sass
I tried removing node-sass and placing dart-sass in it's stead :
npm remove node-sass
npm install dart-sass
ng serve
but this causes :
Module build failed (from ./node_modules/sass-loader/lib/loader.js):
Error: Cannot find module 'node-sass'
for every component in the project.
why is it still looking for node-sass?

this is how adding sass under dart (the js framework) is done, btw : Is Dart integrated with SASS?
but the method doesn't apply for angular.
Update :
I tried using this : How to find reverse dependencies on npm package?
to figure out what was depending/pulling node-sass despite my best efforts and it turns out that was : @angular-devkit/build-angular
but if I remove that then the ng serve is unhappy. it says it needs it.
回答1:
@angular-devkit/build-angular has support for dart sass, only you're using the wrong module, try npm install sass as apposed to dart-sass.
You can see the source code that will confirm this here: https://github.com/angular/angular-cli/pull/11791/commits/2c26bce9a5e2472239d755f585df9458f28b9b7f
回答2:
FWIW, in order to get angular 7.x to use the sass package and not try to install node-sass, I had to:
- remove
@angular-devkit/build-angularfrom my package.json - delete node_modules
- npm install
- npm i -D sass
- add back in the 0.13.10 of
@angular-devkit/build-angularto package.json - npm install again.
