Broccoli error when trying to do ember tutorial

Question

I am at the last step of this part of the ember.js tutorial. https://guides.emberjs.com/v2.14.0/tutorial/installing-addons/

I receive this error when attempting to run the ember server after adding the ember-cli-mirage addon.

steven@steven-VirtualBox:~/em-test$ ember s
Could not start watchman
Visit https://ember-cli.com/user-guide/#watchman for more info.
Livereload server on http://localhost:49153
'instrument' is imported from external module 'ember-data/-debug' but never used
The Broccoli Plugin: [BroccoliMergeTrees: Addon#treeFor (ember-cli-mirage - addon)] failed with:
SyntaxError: Unexpected end of input

Any help parsing this stack? Not sure what any of this is doing at the moment, just trying to get through the tutorial.

如果不看代码，将很难为您提供帮助，但这是一个线索：SyntaxError：输入意外结束检查您是否没有丢失结束标记或简单的内容。
