I've upgraded to Angular CLI 1.7.x and it started working fine. I recommend this solution. I mean upgrading the Angular CLI and it should work for you!

@Yashwanth M solution should work in the worst case scenario!

This is caused by an known issue of angular-cli , the temp fix is

  • Do not reference bootstrap's css/scss in .angular-cli.json,

  • Import bootstrap's scss file in the style.scss file of your app like this:

    scss
@import '~bootstrap/scss/bootstrap.scss';

for more details, please look at my ng-seed repo.

I'm not using angular, but faced with the same issue with bootstrap v."4.0.0":

import "bootstrap/scss/bootstrap.scss";

Adding "autoprefixer": "^7.2.5" to my package.json worked for me.

You can use Bootstrap 4 beta 3, but first edit bootstrap.json/package.json in node_modules/bootstrap:

"browserslist": [
"last 1 major version", <----- delete this line
">= 1%", <----- delete this line
"Chrome >= 45",
"Firefox >= 38",
"Edge >= 12",
"Explorer >= 10",
"iOS >= 9",
"Safari >= 9",
"Android >= 4.4",
"Opera >= 30"
],

It looks like the last n major versions syntax was added in browserList 2.4 and autoprefixer updated to version 2 of browserList in version 7.0.

So, any version of autoprefixer above 7.0 should work.

Updating the autoprefixer should also do the job for you.
