安装sbt应该很容易，但是我尝试了很多不同的东西而没有运气。当我执行“sbt sbt-version”（见下文）时，它会抛出一个异常，因为它找不到sbt-launcher.jar中没有的SshResolver（其他解析器都是）。那为什么要尝试使用SSH呢？我的系统是Windows 7 x64无线连接到comcast电缆调制解调器。由于sbt-launcher由java应用程序运行，我检查了Avast以确保它能够为输入和输出打开任何端口。
我以管理员身份运行sbt，并在日志文件的下方和下方的cmd窗口中获取以下输出。
我渴望得到这个，因为我正在失去参加Coursera Reactive Programming Course的时间。
谢谢！
