嵌套无法解析I18nLanguageInterceptor的依赖项 [英] Nest can't resolve dependencies of the I18nLanguageInterceptor

问题描述

将Nest升级到V8后，使nestjs-i18n工作时出现问题。

这是我收到的错误

Nest can't resolve dependencies of the I18nLanguageInterceptor (I18nOptions, I18nResolvers, I18nService, ?). Please make sure that the argument ModuleRef at index [3] is available in the I18nModule context.

Potential solutions:
 If ModuleRef is a provider, is it part of the current I18nModule?
 If ModuleRef is exported from a separate @Module, is that module imported within I18nModule?
@Module({
  imports: [ /* the Module containing ModuleRef */ ]
 })
 - {"stack":["Error: Nest can't resolve dependencies of the I18nLanguageInterceptor (I18nOptions, I18nResolvers, I18nService, ?).
 
 Please make sure that the argument ModuleRef at index [3] is available in the I18nModule context.

版本：

 "@nestjs/common": "^8.2.0",
 "@nestjs/core": "^8.2.0",
 "nestjs-i18n": "8.2.2",
 "rxjs": "^7.4.0",

感谢您的帮助

推荐答案

基本上，当您有几个ModuleRef类对象的值，使Nest查找错误的值时，会发生这种情况，这会导致x instanceOf ModuleRef(大致在内部完成)返回false

这可能是因为您的项目中有两个@nestjs/coreNodeJS模块。

您可以通过执行以下操作找出这一点

ls -l node_modules/nestjs-i18n/@nestjs
## will display `core` (which is not expected)

ls -l node_modules/@nestjs
## will display `core` (which is expected)

(假设非monorepo项目)
