Details

I want to transform import { CssBaseline } from '@mui/material'; to import CssBaseline from '@mui/material/CssBaseline ';

My config is

{
                libraryName: '@mui/material',
}

And the output is

 import Typography from "@mui/material/lib/typography";

If I disable libraryDirectory the result is the same if I set libraryDirectory to '' the result is import Typography from "@mui/material//typography";

And if I try the customName customName: (member: string) => '@mui/material/${member}' the result is the same.

How can I transform it? I think that there is a bug.

isnt necessary

Reproduce Steps

build or dev

[xc2]

instead of function, please use string template like customName: '@mui/materials/{{ member }}'

ref: https://rsbuild.dev/config/source/transform-import#customname

btw, import Typography from "@mui/material//typography" would work i think

This works, but the other no. This maybe confusing.

This is not a valid import path:
