How to run a node from swift

Question

I am trying to stop a nodejs server started using forever using below command:

func shell(command: String) -> Int32 {
        let task = Process()
        task.launchPath = "/usr/bin/env"
        task.arguments = ["sh", "-c", command]
        task.launch()
        task.waitUntilExit()
        return task.terminationStatus
    }

shell(command: "$forever_PATH/forever stop node.js")

I am seeing below error:

env: node: No such file or directory
PS:node is located in /usr/local/bin

  func shell(path:String,commandargs: [String]) -> Bool
    {
        let task = Process()
        var ret : Bool = false

      task.launchPath = path
      task.arguments = commandargs
      task.launch()
      task.waitUntilExit()
        if !task.isRunning {
            let status = task.terminationStatus
            if status == 0 {
                ret = true
            } else {
                ret = false
            }
        }
         return ret

    }

Call it as below

shell(path: "/usr/local/bin/node", commandargs: ["PathToforever","stop","nodejsscript.js"])
