在Swift中运行Shell命令 [英] Running shell commands in Swift

问题描述

我正在尝试在OSX应用程序中使用Swift运行Shell命令.

I'm trying to run shell commands using Swift in my OSX app.

运行基本命令(例如echo)可以正常工作，但以下情况会引发

Running basic commands such as echo work fine but the following throws

"env:节点:没有这样的文件或目录"

"env: node: No such file or directory"

@IBAction func streamTorrent(sender: AnyObject) {
  shell("node", "-v")
}

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

在运行系统命令时，我还会收到"sh:node:not found"命令.

I also get "sh: node: command not found" when running the system command.

system("node -v")

更新:

不如下面的一些建议那么好，但是我设法将命令回显到文件中，并在终端中打开并执行该命令:

Not as nice as some of the suggestions below, but I managed to echo the command into a file and have it opened and executed in terminal:

system("echo node -v > ~/installation.command; chmod +x ~/installation.command; open ~/installation.command")

推荐答案

对此进行了更多研究.

nodejs安装程序使用/usr/local/bin，对于从Finder启动的应用程序，/usr/local/bin不包含在PATH中:

The nodejs installer uses /usr/local/bin, which is not included in the PATH for applications launched from Finder:

/usr/bin:/bin:/usr/sbin:/sbin

通过/etc/profile和/etc/profile，该目录包含在为bash设置的PATH中. path_helper :

The directory is included in the PATH set for bash via /etc/profile & path_helper:

/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

选项:

• 只需编写/usr/local/bin/node而不是node.

通过environment属性调整NSTask使用的PATH.

使用 setenv 将PATH更改为system-也将影响NSTask.

Use setenv to change the PATH for system — will also affect NSTask.
