Module build failed:

Can you show the scss file where you define the theme?
I was facing this issue because I was using wrong parameters for default, lighter and darker for some colors.

I was using:

$app-primary: mat-palette($mat-blue-grey, A700, A500, A900);

But if you go to the definition of $mat-blue-grey in _theme.scss of material, those variables are not defined, just a few have the 'A' before:

$mat-blue-grey: (
  50: #eceff1,
  100: #cfd8dc,
  200: #b0bec5,
  300: #90a4ae,
  400: #78909c,
  500: #607d8b,
  600: #546e7a,
  700: #455a64,
  800: #37474f,
  900: #263238,
  A100: #cfd8dc,
  A200: #b0bec5,
  A400: #78909c,
  A700: #455a64,
  contrast: (
    50: $black-87-opacity,
    100: $black-87-opacity,
    200: $black-87-opacity,
    300: $black-87-opacity,
    400: white,
    500: white,
    600: $white-87-opacity,
    700: $white-87-opacity,
    800: $white-87-opacity,
    900: $white-87-opacity,
    A100: $black-87-opacity,
    A200: $black-87-opacity,
    A400: white,
    A700: $white-87-opacity,
  )
);

Using only the numbers and removing the 'A' before, fixed the issue for me.

$app-primary: mat-palette($mat-blue-grey, 700, 500, 900);

Did you cleanup your node_modules? maybe it got cached. Since all the people that were having this issue said it was fixed.

emoralesb05 on 12 Jun 2017

The solution was to install the nightly build, I m not a big fan of this solution but it works :)
npm install --save https://github.com/Teradata/covalent-nightly.git

ranouf on 12 Jun 2017

🤔 thats weird cause the nightly build is almost exactly the same as beta.5, can you try reinstalling?

emoralesb05 on 13 Jun 2017

@emoralesb05,
So I deleted the node_modules directory then I changed the covalent/core package version to ^1.0.0-beta.5-1 and now every thing works correctly. The problem comes from only from ^1.0.0-beta.5.

ranouf on 14 Jun 2017

Huh, thats weird. But good to know it all works now 😄

That’s straight from angular material https://material.angular.io/guide/theming which is straight from the material color spec https://material.io/guidelines/style/color.html

Typical we use 100 for the lighter hue and 900 for the darker

kyleledbetter on 1 Feb 2018

Note to future self

This issue can occur when you pass a _theme_ map to mat-color instead of a _palette_ such as $primary (as in $primary: map-get($theme, primary);).

For example If you have

background: mat-color($theme, darker);

you need

background: mat-color(map-get($theme, primary), darker);
