swift – 命令行“无法访问启动路径”

我决定看看我是否可以使用它来构建我的Xamarin项目.

不幸的是我收到以下错误,我不知道如何解决它.

*** Terminating app due to uncaught exception ‘NSInvalidArgumentException’,reason: ‘launch path not accessible’

这是我的脚本：

#!/usr/bin/env swift

import Foundation

print("Building Script")

let fileManager = NSFileManager.defaultManager()
let path = fileManager.currentDirectoryPath

func shell(launchPath: String,arguments: [String] = []) -> NSString? {

    let task = NSTask()
    task.launchPath = launchPath
    task.arguments = arguments

    let pipe = NSPipe()
    task.standardOutput = pipe
    task.launch()

    let data = pipe.fileHandleForReading.readDataToEndOfFile()
    let output = NSString(data: data,encoding: NSUTF8StringEncoding)

    return output
}

if let output = shell("/Applications/Xamarin Studio.app/Contents/MacOS/mdtool",arguments: ["-v build",""--configuration:Beta|iPhone"","MyApp.iOS.sln"]) {
    print(output)
}

有什么想法吗？
