JHipster JDL没有生成任何内容，因为必须传递数据库类型 [英] JHipster JDL not generating anything because the database type must be passed

问题描述

我正在使用Jhipster 4.5.3从我创建的JDL文件生成一些代码。因为我无法生成任何内容，所以我参加了 JDL Blog示例 ......我有同样的问题。

I'm using Jhipster 4.5.3 to generate some code from a JDL file I've created. Because I couldn't generate anything, I took the JDL Blog sample... and I have the same issues.

JDL文档仍然提到：

您可以通过运行jhipster import-jdl your-jdl-file.jh

You can generate entities from a JDL file by running jhipster import-jdl your-jdl-file.jh

但是当我这样做时，我得到：

But when I do that I get :

jdl正在解析。
{name：'NullPointerException'，
message：'必须传递已解析的JDL内容和数据库类型。'，

The jdl is being parsed. { name: 'NullPointerException', message: 'The parsed JDL content and the database type must be passed.',

在代码中查找 / a>，看起来我们必须传递一个新参数，即数据库类型（这在文档BTW中没有提到）。 再次查看代码，有很多数据库类型可供选择。但是我选择的任何数据库，我得到

Looking at the code, it looks like we have to pass a new parameter, the database type (this is not mentioned in the doc BTW). Looking at the code again, there are quite a few database types to choose from. But any database I choose, I get

错误：
找不到postgresql，确保路径正确！

Error: Could not find postgresql, make sure the path is correct!

任何想法？

推荐答案

您是否首先使用'yo jhipster'生成应用程序？你能发布生成的.yo-rc.json吗？

Did you generate an app with 'yo jhipster' first ? Can you post the generated .yo-rc.json ?
