linux - -bash: $: command not found when installing Dart package -

I'm trying to install.

I have my terminal path : / users / king / desktop / dart / dart-sdk . I have checked to see if my PATH has changed, and runs $ PATH in the terminal, and I

  Green: ~ king $ resonant $ PATH / usr / bin: / bin: / usr / sbin: / sbin: / usr / local / bin: / users / king / desktop / dart / dart-sdk  

I type

  $ pub global activate stagehand  

and output is

  -bash: $: Command not found  

stagehand.pub Instructions are simple, but I am new to it, so I do not know what is wrong.

Adding ... / dart-sdk / bin to your own path Will happen.
