HelloWorld vert.x 未启动

Question

我正在尝试基于此运行 vert.x HelloWorld 项目： https://vertx.io/blog/vert-x3-says-hello-to-npm-users/

我已经完成了 npm init 并安装了 vertx3-min 3.8.3。 但是当我执行“npm start”时，出现以下错误：

vertxdemo@1.0.0 开始 C:\Users\Tiago Redaelli\Desktop\VertxDemo

vertx 运行 server.js

C:\Users\Tiago Redaelli\Desktop\VertxDemo>#!/bin/sh

示例中尝试启动 server.js 的部分如下所示：

"start": "./node_modules/.bin/vertx run server.js"

这是项目目录

更新

安装 vertx 3.8 并设置 C:\Program Files\vertx\bin 的路径后，我可以输入“vertx 版本”，但它仍然抱怨 shell 文件中的内容，如前所述。

这是 start 命令引用的文件：

#!/bin/sh
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")

case `uname` in
    *CYGWIN*|*MINGW*|*MSYS*) basedir=`cygpath -w "$basedir"`;;
esac

if [ -x "$basedir//bin/bash" ]; then
  "$basedir//bin/bash"  "$basedir/../vertx3-min/vertx/bin/vertx" "$@"
  ret=$?
else 
  /bin/bash  "$basedir/../vertx3-min/vertx/bin/vertx" "$@"
  ret=$?
fi
exit $ret

Answer 1

您使用的是 windows 操作系统，因此您的启动脚本应该是 bat 之一：

vertx.bat

尝试用该命令替换以前的命令，您的应用程序应该可以工作。
