错误：使用未解析的标识符“进程”

Question

操作系统：Ubuntu 16.04

Swift 版本：3.0 预览版 6

我正在关注这个getting started page

在greeter.swift

func sayHello(name: String) {
  print("Hello, \(name)!")
}

在main.swift

if Process.arguments.count != 2 {
    print("Usage: hello NAME")
} else {
    let name = Process.arguments[1]
    SayHello(name: name)
}

我收到错误

$ swift build
Compile Swift Module 'myapp' (2 sources)
/Sources/main.swift:1:4: error: use of unresolved identifier 'Process'
if Process.arguments.count != 2 {
   ^~~~~~~
/Sources/main.swift:4:16: error: use of unresolved identifier 'Process'
    let name = Process.arguments[1]

Answer 1

在 swift 3.0 中进程已更改为命令行

尝试将Process 替换为CommandLine
