Question

我开始做一些Angular教程，我无法在OSX Yosemite上启动npm。

以下是错误日志。我似乎已按照说明操作，但无法在localhost：3000上看到已编译的应用程序。

问题得到解决。真正的问题不是连接到localhost：3000，但是导轨没有正确安装。当我运行＆＃34; rails server＆＃34;有一条错误行说：

{
        Process p;
    try
    { 
        //  Run root command
        p = Runtime.getRuntime().exec("su"); 

        // Attempt to write a file to system
        DataOutputStream os = new DataOutputStream(p.getOutputStream()); 
        os.writeBytes("echo \"Do I have root?\" >/system/temporary.txt\n");

        // Close the stream
        os.writeBytes("exit\n"); 
        os.flush(); 
        try
        { 
            p.waitFor(); 
            if (p.exitValue() != 255)
            { 
                // Code to run on ROOTED
                //  NOTHING JUST GO FORWARD
            }
            else
            { 
                // Code to run on NON ROOTED

            } 
        }
        catch (InterruptedException e)
        { {
            // TODO Code to run with interrupted exception

            }
        } 
    }
    catch (IOException e)
    { 
        // TODO Code to run in input/output exception

    }}}
