【问题描述】：
我对 JHipster 有疑问。我无法在刚从头开始创建的项目中导入任何 JDL 文件。甚至来自 JHipster 的 jdl-samples 也不起作用。我总是遇到同样的错误：
events.js:182
throw er; // Unhandled 'error' event
^
Error: ERROR!
Error while parsing entities from JDL
at Environment.error (/project/node_modules/yeoman-environment/lib/environment.js:140:40)

使用 --debug 选项： 命令：
yo jhipster:import-jdl ~/Downloads/example.jh
输出：
The jdl is being parsed.

我尝试的 JDL 文件来自 JHipster 博客示例，此处为： https://github.com/jhipster/jdl-samples/blob/master/blog.jh

使用
--debug标志运行以获得更详细的错误。另外请添加您的 JDL，以便我们提供帮助 -
