尽管在 Angular 中使用时，引导程序需要 popper.js

Question

I installed bootstrap@next ( v5.0.0-alpha1 ) through npm . i added the bundle JS to the scripts, but after compiling I receive this error:

ERROR in ./node_modules/bootstrap/dist/js/bootstrap.esm.js
Module not found: Error: Can't resolve 'popper.js' in
'./foo/node_modules/bootstrap/dist/js'

The README clearly states ( bold text ):

We provide compiled CSS and JS (bootstrap. ), as well as compiled and minified CSS and JS (bootstrap.min. ). source maps (bootstrap.*.map) are available for use with certain browsers' developer tools. Bundled JS files (bootstrap.bundle.js and minified bootstrap.bundle.min.js) include Popper.

angular.json

"scripts": [
    "node_modules/bootstrap/dist/js/bootstrap.bundle.js",
],

Any idea what I could miss here?

Answer 1

It should be enough for the popper to be just listed in package.json. I had the same issue and upon deleting "node_modules/bootstrap/dist/js/bootstrap.bundle.js" it has worked for me.
