swift - 为什么我的 Swift Process() 启动路径会输出 `launch path not accessible` ？

Question

            Button(action: {
                let installNano = Process()
                installNano.launchPath = "/opt/pkg/bin/pkgin"
                installNano.launch()
            }) {
            Text("Run pkgin")
            }

我试图做到这一点，以便当按下此按钮时，它将启动 pkgin 二进制文件，并且当运行登录二进制文件时，它应该显示此帮助页面:

我不明白为什么它会给我启动路径无法访问错误，因为我已经检查了我多次使用的启动路径，并且该路径和所有内容都在我的计算机上，所以我不明白为什么这不起作用。当使用Command + Shift + G并输入启动路径时，它会将我带入文件夹并选择pkgin，因此一切肯定都是100%，这让我感到困惑，因为如果一切都在那里，路径应该可以工作。如果您知道为什么这不起作用，那么任何帮助都会有所帮助。

我只需转到我的应用程序的权利并将沙箱从"is"设置为“否”即可解决问题。
