Attempted import error: 'ViewPropTypes' is not exported from 'react-native-web/dist/index'.

[Natetronn]

I tried to access the app using Expo Web and got one error in terminal and one in the browser. It seemed to work fine in Android emulator, however.

Terminal error:

Compiled with warnings.
/home/usnerame/Code/htmlviewExpo/node_modules/react-native-htmlview/HTMLView.js
Attempted import error: 'ViewPropTypes' is not exported from 'react-native-web/dist/index'.

Not sure if it's related but, I saw this issue as well, which also mentions HTMLView.js line 149: #311

And this browser error, which would seem to make sense if ViewPropTypes isn't exported any more by react-native-web. Possibly more on that here: necolas/react-native-web#1537

And a possible solution was suggested here: necolas/react-native-web#1537 (comment) (not sure that's the best way or not but, trying to help troubleshoot or at least research. Hope that helps.)

Initial browser error with no visable app/site:

I tried the above fix i.e. adding export const ViewPropTypes = { style: null }; necolas/react-native-web#1537 (comment) to the bottom of node_modules/react-native-web/dist/index.js and I'm now able to get past the above browser and terminal errors and can see the app/site but, I do get this warning in the browser console:

I ran into the same problem and wound up having to write a patch file using patch-package.

1. In node_modules/react-native-htmlview/HTMLView.js remove ViewPropTypes from the import statement.
2. Below the imports, add the following:

const ViewPropTypes = typeof document !== 'undefined' || Platform.OS === 'web'
  ? PropTypes.shape({style: PropTypes.object})
  : require('react-native').ViewPropTypes || View.propTypes;

3. Then run the following command: npx patch-package react-native-htmlview. This will generate a patch file locally in folder named "patches".
4. Now, in your package.json file, add a postinstall command to your scripts like so:

"scripts": {
  "postinstall": "patch-package"
}

This was what I needed to do so I could get Storybook running under my Expo example app for the project I've been working on.

Thank you much . You saved my time

change all ViewPropTypes.style to PropTypes.style in the source code
don't forget to import PropTypes from "prop-types";
which requires npm install prop-types

[Vytas88]

Thanks everybody for sharing your solution ideas for this.
I am having these ViewPropTypes, requireNativeComponent and other similar Attempted import errors. I took over one React Native and Kotlin Springboot as a backend project.
It helped in the beginning to comment out ViewPropTypes in some files, but there are so many and seems to be never ending. Not sustainable solution.

[BrianWendt]

I ended up removing ViewPropTypes entirely and that got it working with the version of React Native that I'm on (0.69.6)

[radekzz]

Simple solution here:

yarn add deprecated-react-native-prop-types

In node_modules/react-native-htmlview/HTMLView.jsremove ViewPropTypes from the import statement.

Insert import { ViewPropTypes } from 'deprecated-react-native-prop-types'

But i hope that author will update a package so we don't need this anymore.
