fastadmin引用的Bootstrap版本是3.X，我升级到了4.4之后，遇到了这样一个问题。
Uncaught Error: Script error for "popper.js", needed by: bootstrap - require.js。
在bootstrap里定义的是require('popper.js'), 而不是require标准的require('popper'), 所以要在map里做一个转换以让require.js识别。
在require-backend.js文件里面，做如下修改。在paths里面加一个popper，在map里面加一个popper.js，这样就可以了。
require.config({
baseurl: '/assets/js/',
paths: {
'jquery': 'jquery/dist/jquery.min',
'bootstrap': 'bootstrap/dist/js/bootstrap',
'popper': 'poper',//assets/js/目录下面有一个poper.js文件。
...
},
shim: {
'bootstrap': ['jquery']
},
map: {
'*': {
'css': '../libs/require-css/css.min',
'popper.js': 'popper'
}
}
});poper.js文件源码
