我是Typescript和NestJS的新手，正在努力将KeyCloak集成到我的NestJS应用程序中，以将用户添加到KeyCloak。我已经添加了@keyCloak\keyCloak-admin-client 19. x包来处理KeyCloak管理员API。我在执行NestJS应用程序时收到以下错误：
C:\Program Files\nodejs\node.exe .\dist\main.js
Uncaught NodeError Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: F:\MyProj\node_modules\@keycloak\keycloak-admin-client\lib\index.js
require() of ES modules is not supported.
require() of F:\MyProj\node_modules\@keycloak\keycloak-admin-client\lib\index.js from F:\MyProj\dist\user\user.service.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from F:\MyProj\node_modules\@keycloak\keycloak-admin-client\package.json.

更新-1：

我添加了一个没有NestJS的单独typescript项目，安装了@keyCloak\keyCloak-admin-client包并执行了代码。仍然存在相同的错误。
我已经降级到@keyCloak\keyCloak-admin-client 18. x版本，错误消失了！！！
这是否意味着@keyCloak\keycroak-admin-client 19. x版本存在一些问题？是否有任何解决方案可以处理当前版本的keycroak-admin-client包？
更新-2：

如果有人能对此有所了解，那将是有帮助的！！！
当我从18. x切换到19.x时，我遇到了类似的问题。我观察了你的帖子，希望有人能为我解决这个问题：）但最后我自己做了研究。
开发这个库的人在升级版本18时将模块系统从通用JS更改为ES模块-
所以在我的例子中，我“升级”了我的项目，从Common JS模块到ES模块，最后它工作了。但是…更改模块系统并不像只更改TSconfig那么容易（将“模块”从“Common JS”更改为“ESNext”是第一步）。你可以面对更多的问题。我的项目很小，所以我在有限的时间内完成了。我不知道这是否适合你。如何克服从Common JS切换到ES模块时的问题，你可以阅读例如这里：
关于你的UPDATE-2还有一件事。
您将@keyCloak\keycroak-admin-client库设置为Common JS模块的想法很好-然后您可以从项目中导入Common JS模块。但正如我从您附加的代码中了解到的那样：
Uncaught NodeError Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: d:\keycloak-nodejs-admin-client\node_modules\url-join\lib\url-join.js
require() of ES modules is not supported.
require() of e:\NewArchitecture\keycloak-nodejs-admin-client\node_modules\url-join\lib\url-join.js from d:\keycloak-nodejs-admin-client\lib\resources\agent.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename url-join.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from d:\keycloak-nodejs-admin-client\node_modules\url-join\package.json.
一些@keyCloak\keyCloak-admin-client依赖（url-join）使用ES模块，因此@keyCloak\keyCloak-admin-client也需要使用ES模块系统。因此，如果您无法在项目中切换模块系统，并希望将模块系统切换回@keyCloak\keyCloak-admin-client中的Common JS，您还需要注意它的依赖…
ES模块越受欢迎，使用它的npm库就越多，它就会迫使我们开发人员将项目中的模块系统切换到ES模块：）
不幸的是，NestJS仍然不支持导入ES模块，因此我们被迫继续使用以前的版本（18.0.2）
