ERROR in ./node_modules/bootstrap/dist/css/bootstrap.css

Question

I am using angular 5:

build : ng build --prod

Error:

10% building modules 4/6 modules 2 active ...ules/bootstrap/dist/css/bootstrap.css Unknown error from PostCSS plugin. Your current PostCSS version is 6.0.14, but autoprefixer uses
5.2.18.

Perhaps this is the source of the error below.

Perhaps this is the source of the error below.

Answer 1

It worked to me:

1. Edit node_modules\bootstrap\package.json
2. Remove these lines:

"last 1 major version",

">= 1%",
