vue（vue-cli2.x）使用monaco editor时报错

报错

Uncaught (in promise) Error: Unexpected usage
    at EditorSimpleWorker.loadForeignModule (webpack-internal:///./node_modules/monaco-editor/esm/vs/editor/common/services/editorSimpleWorker.js:466)
    at eval (webpack-internal:///./node_modules/monaco-editor/esm/vs/editor/common/services/webWorker.js:41)

除了安装monaco-editor外还需要安装monaco-editor-webpack-plugin并在vue.config.js中配置plugin节点。
