尝试做余烬教程时的西兰花错误

Question

我现在是ember.js教程这一部分的最后一步。 https://guides.emberjs.com/v2.14.0/tutorial/installing-addons/

添加ember-cli-mirage插件后尝试运行ember服务器时收到此错误。

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:

解析此堆栈有帮助吗？ 不确定当前正在做什么，只是试图通过本教程来学习。

Answer 1

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。
