当我尝试在Mac上运行
shell命令时,它按预期工作如下：
scala> import scala.sys.process._ import scala.sys.process._ scala> """protractor --version"""! warning: there were 1 feature warning(s); re-run with -feature for details Version 0.24.0 res12: Int = 0 scala>
但如果我在Windows上这样做,我会得到这个：
scala> import scala.sys.process._
import scala.sys.process._
scala> """protractor --version"""!
warning: there were 1 feature warning(s); re-run with -feature for details
java.io.IOException: Cannot run program "protractor": CreateProcess error=2,The system cannot find the file specified
at java.lang.ProcessBuilder.start(ProcessBuilder.java:1041)
好像我必须在Windows上这样做：
scala> import scala.sys.process._ scala> """C:\Users\twer\AppData\Roaming\npm\protractor.cmd --version"""! warning: there were 1 feature warning(s); re-run with -feature for details Version 0.24.0 res11: Int = 0 scala>
我必须提供命令的完整绝对路径.
但我确信该命令在路径中可用.
反正有没有避免这个？
你可以试试这个：
val command = Seq("protractor","--version")
val os = sys.props("os.name").toLowerCase
val panderToWindows = os match {
case x if x contains "windows" => Seq("cmd","/C") ++ command
case _ => command
}
panderToWindows.!
