错误:使用未解决的标识符“进程”

swift

操作系统:Ubuntu 16.04

Swift版本:3.0预览版6

我正在关注这个入门页面

greeter.swift

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

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]

在Swift 3.0中将进程更改为CommandLine

尝试替换ProcessCommandLine
