vertx 无法部署节点模块

Question

我正在将 vertx 与 npm 一起使用，我想将 googleapis 包含到我的一个 verticle 中。为此，我使用 npm 在项目中安装了 googleapis。 package.json中的节点依赖如下：

 {
   "name": "grey-bshlv",
   "dependencies": {
   "angular": "^1.5.7",
   "googleapis": "^10.0.0",
   "vertx3-full": "^3.3.0"
 },
 "scripts": {
 "start": "./node_modules/.bin/vertx run server.js"
 }

server.js

的内容

var Router = require("vertx-web-js/router");
var eb = vertx.eventBus();
var google = require("googleapis");
vertx.deployVerticle("verticles/static-data-verticle.js");

现在，当我启动 vertx 时，我不断收到错误 "javax.script.ScriptException: Error: Cannot find module googleapis in at line number 141 at column number 6"

下面提供了完整的错误堆栈：

  Failed in deploying verticle

Answer 1

Nashorn 本质上 Vert.x 不是 Node，因此模块如：

fs
路径
网

将不可用，因为它们是节点 specific/native。如果您的依赖项需要这些模块中的任何一个，则无法在 nashorn 中使用它们，因此 vert.x.

文档中有关于它的警告：
