无法运行程序“/Applications/Utilities/Terminal.app&quot ;: error = 13，权限被拒绝 [英] Cannot run program "/Applications/Utilities/Terminal.app": error=13, Permission denied

问题描述

当我运行下面的代码时，我目前遇到很大的麻烦：

I am currently experiencing substantial complications when running the code below:

package practice;

import java.io.IOException;

public class ProgramExecutor {

    public static void main (String [] args){
        try{
            Process p = Runtime.getRuntime().exec("/Applications/Utilities/Terminal.app");
        } catch (IOException e){
            e.printStackTrace();
        }
    }
}

它返回以下错误消息：

java.io.IOException: Cannot run program "/Applications/Utilities/Terminal.app": error=13, Permission denied
    at java.lang.ProcessBuilder.start(ProcessBuilder.java:1048)
    at java.lang.Runtime.exec(Runtime.java:620)
    at java.lang.Runtime.exec(Runtime.java:450)
    at java.lang.Runtime.exec(Runtime.java:347)
    at basicSkills.ProgramExecutor.main(ProgramExecutor.java:9)

    at java.lang.ProcessImpl.start(ProcessImpl.java:134)
    at java.lang.ProcessBuilder.start(ProcessBuilder.java:1029)
    ... 4 more

我将如何解决它。这似乎是由于Mac上的权限问题。我使用chmod命令更改了终端中的权限，但几乎没有成功。还有什么可以为了访问此文件，是否可以以超级用户身份运行Eclipse？

How would I go about resolving it. It appears to be due to a permission issue on my Mac. I have changed the permissions in the Terminal using chmod command with little success. What else could it be? Is it possible to run Eclipse as a super user in order to access this file?

推荐答案

路径'/ Applications / Utilities / Terminal.app'是终端应用程序的路径，它是一个目录。实际的可执行终端程序路径是：

The path '/Applications/Utilities/Terminal.app' is the path to the Terminal application, which is a directory. The actual executable Terminal program path is:

/Applications/Utilities/Terminal.app/Contents/MacOS/Terminal

这是 exec call。

或者使用

open -n /Applications/Utilities/Terminal.app

命令。
