使用 Polymer CLI 1.1.0 在项目的根控制器中运行polymer build后，出现此错误：
info: Clearing build/ directory...
error: Uncaught exception: Error: File not found with singular glob: /home/willie/Projects/World History Final Project/src/passport-app/passport-app.html

我想知道为什么这种情况不断发生。
Polymer CLI 旨在使用 REPL 应用程序外壳架构构建应用程序。在polymer.json文件中，必须定义任何延迟加载的"片段"。将片段添加到文件后，在包含配置文件的目录中运行polymer build。
