Ubuntu 运行闪亮服务器时出错

我试图在Ubuntu中从终端运行shiny server，但收到以下错误：

nik@nik-VirtualBox:~$ shiny-server
[2017-02-13 10:42:28.353] [INFO] shiny-server - Shiny Server v1.5.1.834 (Node.js v6.9.1)

[2017-02-13 10:42:28.508] [ERROR] shiny-server - Error loading config: The user 'nik' does not have permissions to run applications as one of the users in 'shiny'. Please restart shiny-server as one of the users in  'shiny'. (/etc/shiny-server/shiny-server.conf:2:1)
[2017-02-13 10:42:28.510] [INFO] shiny-server - Shutting down worker processes

要在Shining server中运行应用程序，我可以做些什么

新错误：

nik@nik-VirtualBox:~$ sudo shiny-server
[sudo] password for nik:

错误消息是

nik

用户没有权限，我想您可以在命令前添加一个

sudo

。@yundongxu谢谢。它运行，但在出现新错误时关闭。我不太确定是否必须在我的系统中为一个闪亮的应用程序提供一个文件路径，而这可能不是来自root，但我不知道怎么做？@yundongxu我试图在app的特定文件路径中执行sudo shinny server，但再次收到相同的错误。您可以运行

sudo lsof-I:3838

以查看是否有其他进程正在侦听3838端口。如果您看到任何其他进程，请运行

sudokill-9processid

以终止该进程。哦，等等。您可以运行

ps aufx | grep shinny server

查看是否有名为shinny server的进程，我认为shinny server已经自动运行。
