安装 sbt 应该很容易，但我尝试了许多不同的东西，但没有任何运气。当我执行“sbt sbt-version”（见下文）时，它会引发异常，因为它找不到在 sbt-launcher.jar 中不可用的 SshResolver（其他解析器是）。那么它为什么要尝试使用 SSH 呢？我的系统是无线连接到 comcast 电缆调制解调器的 Windows 7 x64。由于 sbt-launcher 是由 java 应用程序运行的，所以我检查了 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 并在日志文件下方和下方的 cmd 窗口中获得以下输出。
由于我正在浪费时间学习 Coursera 反应式编程课程，因此我急于实现这一目标。
谢谢！
