[error] Error: An unexpected error has occurred.

In case others encounter this error, I have found that:

• this error occurs when I run "firebase deploy" from the Integrated Terminal in Visual Studio Code
  
• error does NOT occur when I run "firebase deploy" from a Terminal Window

This on Ubuntu 16.04.

Tim, could you also file a bug report with all the relevant details?

Just want to note, I was having this issue as well. I resolved it by installing the latest version of firebase-tools globally. I.e. I ran

npm install --global firebase-tools@latest

After that I was able to deploy.
