问题


I just installed a fresh Laravel 5.4, and bootstrap 4 alpha 6. Laravel mix wont compile SASS: Here is one error:

    Module build failed: ModuleBuildError: Module build failed: 
$input-height:                   (($font-size-base * $input-line-height) + ($input-padding-y * 2)) !default;
                                ^
      Incompatible units: 'rem' and 'px'.

 @ multi ./resources/assets/js/app.js ./resources/assets/sass/app.scss

Someone passed this? And how?


回答1:


Solved

  1. remove the bootstrap entry from package.json and replace it with "bootstrap": "4.0.0-alpha.6", in resources/assets/sass/app.scss,
  2. comment out the import of variables. change the path of bootstrap to @import "node_modules/bootstrap/scss/bootstrap.scss";
  3. in resources/assets/js/bootstrap.js, look for require('bootsrap-sass'); and change it to require('bootstrap');

Link!




回答2:


It happened to me too, it's like you said, the override of some variables is the cause of this error.

To fix this just comment this line in resources/assets/sass/_variables:

$font-size-base: 14px;

In the variables if you need are using other variables that laravel provides.

回答3:


Just change the '$font-size-base: 14px;' to '$font-size-base: 0.875rem;' and run 'npm run dev'. And done.




回答4:


I just fixed this on my side, what worked for me was moving the @import "bootstrap.scss.." and other variables to the top of the app.scss file, it seems it was overwritten and that is what caused the issue.
