Can't resolve 'material-ui-pickers/utils/MuiPickersUtilsProvider'

[petersg83]

Hello,

I installed react-admin-dateinputs and I'm trying to use TimeInput but I have this error:
Module not found: Can't resolve 'material-ui-pickers/utils/MuiPickersUtilsProvider' in '/Users/pierre/Documents/schoolx/frontend/node_modules/react-admin-date-inputs/lib'

Here is my package.json:

{
"name": "schoolx-frontend",
"version": "0.1.0",
"private": true,
"dependencies": {
"import": "^0.0.6",
"jsonwebtoken": "^8.3.0",
"moment": "^2.22.2",
"ra-data-json-server": "^2.2.0",
"ra-language-english": "^2.2.0",
"ra-language-french": "^2.2.0",
"react": "^16.4.2",
"react-admin": "^2.4.0",
"react-admin-date-inputs": "^1.1.0",
"react-big-calendar": "^0.20.1",
"react-dom": "^16.4.2",
"react-router-dom": "^4.3.1",
"react-scripts": "1.1.4",
"recompose": "^0.28.2"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
}
}

I tried to install the module material-ui-pickers but it didn't change anything.

Do you have an idea of how I can make it work ?
Thanks :)

I am experiencing this as well. Likely related to the breaking changed noted in the material-ui-pickers version 1.0.0 release notes:

-import MuiPickersUtilsProvider from 'material-ui-pickers/utils/MuiPickersUtilsProvider'
+import MuiPickersUtilsProvider from 'material-ui-pickers/MuiPickersUtilsProvider'

#16 It worked for me. Thx @tmcgee

Thanks! I think this is a similar issue, is this change published to npm yet? Which version of material-ui is everyone else using?

./node_modules/material-ui-pickers/utils/date-fns-utils/index.esm.js
Module not found: Can't resolve 'date-fns/addDays' in '~/Documents/<project>/node_modules/material-ui-pickers/utils/date-fns-utils'

This might be related to yet-another-release of material-ui-pickers. Version 2.0.0 this time. From the release notes:

We have moved our utils to the separate monorepo (star it here) and for now do

-import Utils from 'material-ui-pickers/utils/date-fns-utils'
+import Utils from '@date-io/date-fns'

Here is where I think the change should occur. I haven't had the opportunity to verify/fix locally.

Hope this helps.

@vascofg : Any plan to release a new version on npm ?

Hey, unfortunately I won't be able to update to material-ui-pickers stable version since they decided to update to @material-ui/core@^3.2.0 and react-admin is still on @^1.4.0. This is causing some issues with the date-picker modal.

I'll try to publish a fixed version using the latest compatible material-ui-pickers version ASAP.

Fixed in 1.0.21

Hey @vascofg,
I have the same error message, but it's not solved in 1.0.21.

  "dependencies": {
    "@material-ui/core": "^3.2.0",
    "jwt-decode": "^2.2.0",
    "material-ui-chip-input": "^0.19.0",
    "ra-data-json-server": "^2.5.2",
    "ra-data-simple-rest": "^2.5.2",
    "react": "^16.7.0",
    "react-admin": "^2.4.0",
    "react-admin-date-inputs": "^1.0.21",
    "react-dom": "^16.7.0",
    "react-scripts": "2.1.2"
  }

Is the version 1.0.21 compatible with the current version of @material-ui/core 3.2.0 ?
Thanks

I'm getting very similar error message:

./node_modules/material-ui-pickers/utils/date-fns-utils.js`
`Module not found: Can't resolve 'date-fns/addDays' in '<project_dir>/node_modules/material-ui-pickers/utils'

with

"dependencies": {
    "ra-data-simple-rest": "^2.5.3",
    "react": "^16.7.0",
    "react-admin": "^2.5.3",
    "react-admin-date-inputs": "^1.0.21",
    "react-dom": "^16.7.0",
    "react-scripts": "2.1.3"
  }

I'm getting the error too:

Module not found: Error: Can't resolve 'date-fns/addDays' in '/tmp/build_768d2570a4572a43a5b79af1cef23b51/admin/node_modules/material-ui-pickers/utils'

Upgrading to 1.0.21 didn't help.

Installing date-fns v2.0.0-alpha.7 manually did allow the app to build, but then I get weird visual bugs in the date picker, presumably due to breaking changes in version 2 of date-fns.
