在 greeter.swift
greeter.swift
func sayHello(name: String) { print("Hello, \(name)!") }
在 main.swift
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] ^~~~~~~ <unknown>:0: error: build had 1 command failures error: exit(1): swift/bin/swift-build-tool -f .build/debug.yaml
在Swift 3.0中将进程更改为CommandLine
尝试替换Process为CommandLine
Process
CommandLine
这是更改它的提交的链接: 将进程重命名为CommandLine [SE-0086]。
