Can you share your package.json, webpack config, and Babel config?

Can you post your Babel config?

codal-mitalt commented 11 months ago

{
  "presets": ["@babel/preset-env", "@babel/preset-react"],
  "plugins": [
    "@babel/plugin-syntax-dynamic-import",
    "@babel/plugin-proposal-class-properties",
    "@babel/plugin-transform-optional-chaining"
  ]
}

JLHwung commented 11 months ago

Thanks. The error comes from your node_modules, specifically the ml-matrix library. As node_modules has been excluded from the babel-loader, Babel can not transform that code for you. Please enable Babel for the ml-matrix library.

// webpack.config.js
{
  rules: [
  {
    test: /\.(?:js|mjs|cjs)$/,
    exclude: {
      and: [/node_modules/], // Exclude libraries in node_modules ...
      not: [
        // Except for a few of them that needs to be transpiled because they use modern syntax
        /ml-matrix/,
      ]
    },
    use: {
      loader: 'babel-loader',
      options: {
        presets: [
          ['@babel/preset-env', '@babel/preset-react']
        ]
      }
    }
  }
]}

Please consider upgrade @babel/core and @babel/preset-env to the latest version, then these three plugins can be safely removed as they have been included in the preset-env.

    "@babel/plugin-syntax-dynamic-import",
    "@babel/plugin-proposal-class-properties",
