I'm currently setting up a node.js server and I'm using the debug module here https://github.com/visionmedia/debug.

我正在尝试启用它，以便我可以在输出中获取彩色调试信息，但是我的终端看起来像底部的最后一个终端屏幕，它说:

推荐答案

tty 是那些时髦的 Unix 命令之一，它将连接到标准输入的终端的名称打印(或显示)到标准输出.

tty is one of those funky Unix commands that prints (or, displays) to standard output the name of the terminal connected to standard input.

这些通常用作访问计算机以修复问题的一种方式，而无需实际登录可能已损坏的桌面.

These are commonly used as a way to get access to the computer to fix things, without actually logging into a possibly b0rked desktop.

默认情况下，Ubuntu 有 7 个 tty.

By default Ubuntu has 7 tty's.

1-6 仅是命令行，7 运行您的 X 会话(您的普通桌面).

1-6 are command line only, 7 runs your X session (your normal desktop).

要访问它们，请使用此键盘快捷键:

To access them, use this keyboard shortcut:

Ctrl + Alt + F1

Ctrl + Alt + F1

(将 F1 改为 F1-F6 以访问您需要的终端)

(changing F1 to F1-F6 to access the terminal that you need)

要返回您的 X 会话(普通桌面)，

To get back to your X session (the normal desktop),

Ctrl + Alt + F7

Ctrl + Alt + F7
