无法导入jdl文件

JHipster有问题。我无法从刚从头开始创建的项目中导入任何JDL文件。即使JHipster的jdl样本也不起作用。我总是得到同样的错误：无法导入jdl文件

events.js:182 
    throw er; // Unhandled 'error' event 
^

Error: ERROR! 
Error while parsing entities from JDL

与--debug选项：命令：

yo jhipster:import-jdl ~/Downloads/example.jh

输出：

The jdl is being parsed.

我尝试的JDL文件从JHipster Blog-示例在此处找到： 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。也请添加你的JDL，所以我们可以帮助 –

@JonRuddell我编辑了帖子并添加了信息 –

您正在尝试生成在NoSQL项目中使用关系的实体。 NoSQL项目的JHipster不支持关系。有关JHipster如何处理关系的详细信息，请参阅Managing Relationships文档：

Relationships only work when JPA is used. If you choose to use Cassandra or MongoDB, they won’t be available.

卸下关系使JDL进口。您还可以尝试使用SQL数据库选项进行项目。

未来版本的JHipster（v4.10.0 +）中的JDL错误消息更加冗长，因此将来不需要使用--debug标志。
