Swift Terminal Emulator：复杂命令中的错误

Question

我尝试使用Swift创建终端仿真器，到目前为止我已经获得了所有基本功能。我可以发送diskutil list之类的命令并获得正确的输出。但是，如果我要求程序在任何方面都是交互式的，例如用户必须指定密码的sudo reboot，我会收到错误sudo: no tty present and no askpass program specified;或者当我想使用nano anyTextFile.txt时，我会收到类似Error opening terminal: unknown.的错误，我在Process类中看不到与指定有关的任何内容TTY或askpass（无论是什么）

这里的代码应与此问题相关：

func shell(_ args: String) -> (output: [String], error: [String], exitCode: Int32) {
    var output : [String] = []
    var error : [String] = []


    let task = Process()
    task.launchPath = "/usr/bin/env"
    let cmd = args.characters.split(separator: " ").map(String.init)
    task.arguments = cmd

    let outpipe = Pipe()
    task.standardOutput = outpipe
    let errpipe = Pipe()
    task.standardError = errpipe

    task.launch()

    let outdata = outpipe.fileHandleForReading.readDataToEndOfFile()
    if var string = String(data: outdata, encoding: .utf8) {
        string = string.trimmingCharacters(in: .newlines)
        output = string.components(separatedBy: "\n")
    }

    let errdata = errpipe.fileHandleForReading.readDataToEndOfFile()
    if var string = String(data: errdata, encoding: .utf8) {
        string = string.trimmingCharacters(in: .newlines)
        error = string.components(separatedBy: "\n")
    }

    task.waitUntilExit()
    let status = task.terminationStatus

    return (output, error, status)
}
