Question

安装ngrx Store ngrx效果并编写我的action，reducer和效果。核心has-no exported-ember-eefactorydef“> this 如此类似的问题，但它仍然一样，

这是控制台中的错误，

Answer 1

确保您的@ngrx/store（和其他NGRX模块）版本与您的Angular版本相符。当我安装了最新的NGRX（13.2.0）时，我遇到了这个错误

Answer 2

我的错误：错误：node_modules/@ngrx/store/src/models.d.ts：1：10-错误ts2305：模块'“@angular/core”'没有导出的成员'importedngmoduleproviders'。

我的Angular版本是13，所以我将NGRX 的版本降级为“@ngrx/store”：“^13.2.0” “@ngrx/store-devtools”：“^13.2。 0“
