React native 无法启用实验语法'；classProperties'；在使用react本机元素的混合react本机web项目中

我正在关注这一点

我的项目是使用

我和nb联系过他

这是我的教程显示了有罪的代码

因此，Thread android按预期工作，但Thread web无法编译：

Failed to compile
./node_modules/react-native-ratings/src/SwipeRating.js
SyntaxError: /home/pmy/gitphone/node_modules/react-native-ratings/src/SwipeRating.js: Support for the experimental syntax 'classProperties' isn't currently enabled (41:23):

  39 | 
  40 | export default class SwipeRating extends Component {
> 41 |   static defaultProps = {
     |                       ^
  42 |     type: 'star',
  43 |     ratingImage: require('./images/star.png'),
  44 |     ratingColor: '#f1c40f',

Add @babel/plugin-proposal-class-properties (https://git.io/vb4SL) to the 'plugins' section of your Babel config to enable transformation.
This error occurred during the build time and cannot be dismissed.

注意，所有其他问题，在这里，请不要特别提及CRWNA&没有一个建议对我有效&我已经尝试了很多

我的问题是如何配置它，以便纱线网按预期工作？

您可以共享整个defaultProps部分吗？@FatihMertDoğancan没有defaultProps部分可共享！通过运行CRWNA、安装并链接RNE和RVI以及制作一个基本的主组件（包括两个输入字段和一个提交按钮），我只创建了一个样板文件。Android还可以，web Fails我在react native elements上发布了另一个问题，它似乎是troubleNB的来源。我可以使用react native ratings的早期版本，它不使用非标准的实验性代码，这些代码可能无论如何都不应该出现在npm中。。。不过我还是希望其他人能给我一个更好的答案！你能分享整个defaultProps部分吗？@FatihMertDoğancan没有defaultProps部分可以分享！通过运行CRWNA、安装并链接RNE和RVI以及制作一个基本的主组件（包括两个输入字段和一个提交按钮），我只创建了一个样板文件。Android还可以，web Fails我在react native elements上发布了另一个问题，它似乎是troubleNB的来源。我可以使用react native ratings的早期版本，它不使用非标准的实验性代码，这些代码可能无论如何都不应该出现在npm中。。。不过我还是希望其他人能给我一个更好的答案！
