我只是想使用webpack5和webpack-cli启动一个新的打字稿项目。令我惊讶的是，我遇到了这些错误：

Webpack.config.js：

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

module.exports = {
  mode: 'development',
  entry: './src/index.ts',
  plugins: [new webpack.ProgressPlugin()],

  module: {
    rules: [{
      test: /\.(ts|tsx)$/,
      loader: 'ts-loader',
      include: [path.resolve(__dirname, 'src')],
      exclude: [/node_modules/]
    }]
  },

  resolve: {
    extensions: ['.tsx', '.ts', '.js']
  }
}

Tsconfig.json：

{
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "noImplicitAny": true,
    "module": "es6",
    "target": "es5",
    "allowJs": true,
    "skipLibCheck": true
  },
  "exclude": [
    "node_modules"

}

Answer 1

因此，事实证明我不得不更改tsconfig选项include来指定打字稿将分析的目录。

根据documentation on include option，默认值为：

[]如果指定了文件，否则为[“ ** / *”]

因此，默认行为是分析所有存储库，包括node_modules。

解决方案：

总而言之，只需编辑include属性即可仅包含src文件夹：

{
  "include": ["src/**/*"]
}
