Angular CLI SCSS module build failed on windows

Question

I have created a new angular application with the angular cli (ng new my-app --style=scss). Both ng serve and ng build fail if any scss file has any content (even the initial comment in styles.scss fails to compile):

body { display: block; }

Module build failed (from ./node_modules/sass-loader/lib/loader.js): TypeError: Instance of 'dz': type 'dz' is not a subtype of type 'n'

My system:

• Angular CLI: 7.0.3
• Node: 8.9.3
• OS: win32 x64
• node-sass: 4.10.0
• sass-loader: 7.1.0
• npm: 6.4.1

It works on another windows machine.

Answer 1

After uninstalling global sass with npm uninstall -g sass, the build worked.
