Android Swift can'；t执行adb和命令行指令

我正在尝试在macOS应用程序中使用swift执行命令行指令。 代码如下：

@discardableResult
static func shell(_ args: String...) -> Int32
{
    let task = Process()
    task.launchPath = "/usr/bin/env"
    task.arguments = args
    task.launch()
    task.waitUntilExit()
    return task.terminationStatus
}

@discardableResult
static func shellAdb(_ args: String...) -> Int32
{
    let task = Process()
    task.launchPath = "/Users/myname/Library/Android/sdk/platform-tools"
    task.arguments = args
    task.launch()
    task.waitUntilExit()
    return task.terminationStatus
}

我使用'adb--v'和'echo hello'字符串并将其传递给'shell'函数

我还尝试了第一个命令的“shellAdb”函数，但它也不起作用

如果使用“shell”函数，则会出现以下错误：

env: adb --v: No such file or directory
env: echo 'hello': No such file or directory

两者的错误代码均为“127”

如果使用“shellAdb”函数，则会出现以下其他错误：

这个问题在shell和shellAdb函数中都存在，但它们看起来像我已经找到的示例

---

我使用的是Swift 3、macOS 10.12.5和Xcode 8.3.2

shellAdb函数中的启动路径看起来像一个目录，而不是指向可执行文件的（完整）路径，应该是这样。@MartinR使用“shellAdb”函数解决了这个问题。我想知道为什么“echo hello”函数返回

127

错误。
