安装npm Install imports-loader and exports-loader 

在webpack配置文件（webpack.config.js）当中 modules.rules 加入：

{
  test: require.resolve("three/examples/js/controls/OrbitControls"),
  use: "imports-loader?THREE=three"
},
{
  test: require.resolve("three/examples/js/controls/OrbitControls"),
  use: "exports-loader?THREE.OrbitControls"
}

在使用的地方，import:

import OrbitControls from "three/examples/js/controls/OrbitControls";
