添加反应本机矢量图标以反应本机与反应本机 Web 时出错

Question

我按照本教程添加到react-native-web项目中react-native。但我在添加react-native-vector-icons到项目时遇到错误。

./node_modules/react-native-vector-icons/lib/create-icon-set.js
SyntaxError: /home/hamidreza/Desktop/myApp/node_modules/react-native-vector-icons/lib/create-icon-set.js: Support for the experimental syntax 'classProperties' isn't currently enabled (43:22):

  41 | 
  42 |   class Icon extends PureComponent {
> 43 |     static propTypes = {
     |                      ^
  44 |       allowFontScaling: PropTypes.bool,
  45 |       name: IconNamePropType,
  46 |       size: PropTypes.number,

我也将我的更改babel.config.js为：

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: [
    [
      '@babel/plugin-proposal-class-properties',
      {
        loose: true,
      },
    ],
  ],
};

或者

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: [
    '@babel/plugin-proposal-class-properties'
  ],
};

但仍然有问题。

我应该怎么办？

通过增加

path.resolve(appDirectory, 'node_modules/react-native-vector-icons'),

问题babelLoaderConfiguration解决。

最终的web/webpack.config.js：

const path = require('path');
const webpack = require('webpack');

const appDirectory = path.resolve(__dirname, '../');
const babelLoaderConfiguration = {
  test: /\.js$/,
  include: [
    path.resolve(appDirectory, 'index.web.js'),
    path.resolve(appDirectory, 'src'),
    path.resolve(appDirectory, 'node_modules/react-native-uncompiled'),
    path.resolve(appDirectory, 'node_modules/react-native-vector-icons'),
    path.resolve(appDirectory, 'node_modules/react-native-elements'),
  ],
  use: {
    loader: 'babel-loader',
    options: {
      cacheDirectory: true,
      presets: ['react-native'],
      plugins: ['react-native-web'],
    },
  },
};

const imageLoaderConfiguration = {
  test: /\.(gif|jpe?g|png|svg)$/,
  use: {
    loader: 'url-loader',
    options: {
      name: '[name].[ext]',
    },
  },
};

module.exports = {
  entry: [path.resolve(appDirectory, 'index.web.js')],

  output: {
    filename: 'bundle.web.js',
    path: path.resolve(appDirectory, 'dist'),
  },
  module: {
    rules: [babelLoaderConfiguration, imageLoaderConfiguration],
  },

  resolve: {
    alias: {
      'react-native$': 'react-native-web',
    },
    extensions: ['.web.js', '.js'],
  },
};
