我正在写Eclipse plug-in for Vert.x 。当使用如下命令行启动 hello-vorld.js 时:
D:\Progs\vertx\vert.x-2.1M5\bin\vertx.bat 运行 D:\Workspaces\runtime-EclipseApplication\Vertx2\hello-vorld.js
我两次遇到同样的错误:
Failed in deploying verticle

hello-vorld.js 包含
var vertx = require('vertx');
vertx.createHttpServer().requestHandler(function(req) {
req.response.end("Hello World!");
}).listen(8080, 'localhost');
最佳答案
Vert.x 将 D: 作为语言运行时限定符。
用途:
D:\Progs\vertx\vert.x-2.1M5\bin\vertx.bat run rhino:D:/Workspaces/runtime-EclipseApplication/Vertx2\hello-vorld.js
