[ESM] Vite + vitest + @mui/material v5.11.0 - createPalette.js:1 seems to be an ES Module but shipped in a CommonJS package.

[borgfriend]

When using vite@4.0.4 and vitest@0.26.3 with @mui/material.

Starting with "@mui/material": "5.11.0",

I am getting the following error:

Module /<project_name>/node_modules/@mui/material/styles/createPalette.js:1 seems to be an ES Module but shipped in a CommonJS package. You might want to create an issue to the package "@mui/material" asking them to ship the file in .mjs extension or add "type": "module" in their package.json.

As a temporary workaround you can try to inline the package by updating your config:

// vitest.config.js
export default {
  test: {
    deps: {
      inline: [
        "@mui/material"
      ]
    }
  }
}

Following the advice from the error message does not fix the issue.

For the time being I reverted back to "@mui/material": "5.10.17" - the tests run without any issue.

Any advice on how to use the current version?

Are you importing stuff directly from this file? I am asking because that is not supported. We allow imports up to level3, for e.g. @mui/material/styles. All imports which are valid should work as expected. I guess this may be related to https://github.com/mui/material-ui/issues/35480

If this is not the case, please share e reproduction repository where we can check the issue.

We are not importing anything directly from this file.

I am encountering the problem with this repository https://github.com/catenax-ng/product-item-relationship-service-frontend.

I am experiencing a similar issue when trying to access TablePaginationActions.

I wanted to add a new control to TablePaginationActions , but still maintain current behaviour. TablePaginationActions is imported from @mui/material/TablePagination/TablePaginationActions which, due to being a level4 import is causing the above issue.

Is it possible that we can export TablePaginationActions from @mui/material/TablePagination?

I also just received this error with vitest, but I have been trying @mui/material-next with it.

The following change fixed it for me:

// import Chip from "@mui/material-next/Chip";
import Chip from "@mui/material/Chip";

I'm not sure if there are other things that cause this, but I wanted to pass this on in case it helps someone.

EDIT: adding package.json versions:

    "@mui/icons-material": "^5.15.10",
    "@mui/lab": "5.0.0-alpha.165",
    "@mui/material": "^5.15.10",
    "@mui/material-next": "6.0.0-alpha.123",
