这个错误是由于在 Vue 2 项目中使用 G6 v5.0.43 时，Webpack 没有正确配置以处理私有字段（例如 #matrix）导致的。私有字段是 JavaScript 的一种新特性，可能需要更新的 Babel 配置或 Webpack 加载器来支持。

以下是一些可能的解决方案：

1. 更新 Babel 配置：

   • 确保 Babel 配置中包含对私有字段的支持。你可以在 .babelrc 或 babel.config.js 中添加以下插件：

     {
       "plugins": ["@babel/plugin-proposal-class-properties", "@babel/plugin-proposal-private-methods"]
     }

2. 更新 Webpack 配置：

   • 确保 Webpack 配置中使用了 Babel 加载器来处理 JavaScript 文件。你可以在 webpack.config.js 中添加或更新 Babel 加载器的配置：

     module: {
       rules: [
         {
           test: /\.js$/,
           exclude: /node_modules/,
           use: {
             loader: 'babel-loader',
             options: {
               presets: ['@babel/preset-env'],
               plugins: ['@babel/plugin-proposal-class-properties', '@babel/plugin-proposal-private-methods']
             }
           }
         }
       ]
     }

3. 检查依赖版本：

   • 确保所有相关依赖（如 Babel、Webpack、G6 等）都是最新版本，因为较新的版本可能已经修复了相关问题。

如果这些方法仍然无法解决问题，请告诉我，我会进一步帮助你。
