Question

我在写Eclipse plug-in for Vert.x。使用命令行启动hello-vorld.js时：

D:\Progs\vertx\vert.x-2.1M5\bin\vertx.bat run D:\Workspaces\runtime-EclipseApplication\Vertx2\hello-vorld.js

我两次得到同样的错误：

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');

Answer 1

Vert.x将D:作为语言运行时限定符。

使用：

D:\Progs\vertx\vert.x-2.1M5\bin\vertx.bat run rhino:D:/Workspaces/runtime-EclipseApplication/Vertx2\hello-vorld.js

Vert.x - java.lang.IllegalStateException：没有针对前缀D的语言实现
