I ran into that - in my case Phoenix distribution didn’t include glyphicons-halflings-regular - i.e. bootstrap is incomplete.
There needs to be a static/fonts folder with:
glyphicons-halflings-regular.eot
glyphicons-halflings-regular.svg
glyphicons-halflings-regular.ttf
glyphicons-halflings-regular.woff
glyphicons-halflings-regular.woff2
The app.css file has the bootstrap CSS baked in which references these fonts.
“eonasdan-bootstrap-datetimepicker”: [‘build/bootstrap-datetimepicker.min.css’],doesn’t look like a path undernode_modules(hence the name of the configuration:npm)
You’d have to look at modifying
stylesheets: {
joinTo: "css/app.css"
},
instead.
The joinTo supports a variety of pattern matching styles.
