Failed to compile the react-admin demo because of changes in @babel/runtime

[nikri]

When I have added the first part to the app.js and installed til ra-data-json-server, it gives me the following error:

Failed to compile.

./node_modules/@material-ui/icons/HotTub.js
Module not found: Can't resolve '@babel/runtime/helpers/builtin/interopRequireDefault' in '/Users/gan-nikri/GIT/react-admin/node_modules/@material-ui/icons'

It looks like there has been an update to babel runtime, where they have removed the folder "builtin", which results in the icons in the material-ui is failing.

Temporary fix for getting the demo to work:

Downgrade Babel Runtime to v7.0.0-beta.55:
yarn add @babel/[email protected] --exact

This will remove the bug, until Babel and Material-ui is compatible to each other again.

Environment

• React-admin version: 2.2.0
• React version: 16.4.2
• Browser: Chrome latest
• Babel runtime version: 7.0.0-rc1
• Material-ui-core version: 1.5.1
• Material-ui-icons version: 1.1.0

+1, same issue here. Thanks for opening the issue & the workaround, was just about to open one myself! This issue is independent of the data provider used.

This is a material-ui bug: mui/material-ui#12408

[nikri]

It doesn't look like it's added to a milestone yet :) Anyway, it works with the downgrade, so I'm happy. And it's an awesome solution you guys have build btw @fzaninotto

Another workaround I found was to upgrade @material-ui/icons to version 2.0.3

Indeed there is an incompatibility issue between material-ui/core version 1.5.1 and material-ui/icons 1.1.1 which are the last available v1.* version to date.
more infos: mui/material-ui#12621

So anyone trying to link with react-admin will have the issue.

You should probably fix the version of dependencies to the last one compatible by removing the caret:
"@material-ui/core": "^1.4.0",
"@material-ui/icons": "^1.0.0",

Replacing by the following should fixe the issue definitely:
"@material-ui/core": "1.5.0",
"@material-ui/icons": "1.1.0",

Thanks anyway.
