typescript意外的令牌导入

当使用一个简单的 import 在node.js基本代码中。 我想知道我的配置文件有什么问题,以及如何修复它:

(function (exports, require, module, __filename, __dirname) { import { IO } from "fp-ts/lib/IO";
                                                              ^^^^^^

SyntaxError: Unexpected token import

我使用的是typescript,这里是我的配置文件:

tsconfig.json文件

{
    "compilerOptions": {
        "target": "es2017",
        "module": "commonjs",
        "sourceMap": true,
        "strict": true,
        "noUnusedLocals": true,
        "noUnusedParameters": true,
        "noImplicitReturns": true,
        "noFallthroughCasesInSwitch": true,
        "moduleResolution": "node",
        "baseUrl": "."
    }
}

const path = require('path');

module.exports = {
  entry: 'index.ts',
  devtool: 'source-map',
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        use: 'ts-loader',
        exclude: /node_modules/
      }
    ]
  },
  resolve: {
    extensions: [ '.ts' ]
  },
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist')
  }
};
