商店 'someStore' 不可用！确保它是由某些提供商提供的

Question

我正在尝试使用 React、Typescript 和 MobX 构建一个新项目。

出于某种原因，我无法让 MobX 工作。这是一段相对简单的代码，但它给了我这个错误。

未捕获错误：MobX 注入器：商店 'appState' 不可用！确保它是由某些提供商提供的

这是我的代码：

AppState.ts

import {observable} from "mobx"
import {observer} from "mobx-react"

export class AppState {
    @observable public greeting = "hello World"
}

index.tsx

import * as React from "react"
import * as ReactDOM from "react-dom"
import { Provider } from "mobx-react"
import { Router, Route, Switch } from "react-router"
import { createBrowserHistory } from "history"
import MuiThemeProvider from "material-ui/styles/MuiThemeProvider"
"./containers/BookingStep/BookingStepContainer";
import { TestContainer } from "./containers/TestContainer";
import { AppState } from "./store/AppState";

const history = createBrowserHistory()

ReactDOM.render(
  <Provider store={AppState}>
    <Router history={history}>
      <Switch>
        <MuiThemeProvider>
          <div>
            <Route path="/test" component={TestContainer} />
          </div>
        </MuiThemeProvider>
      </Switch>
  </Router>
</Provider>,
document.getElementById("root"))

TestContainer.tsx

import * as React from "react"
import { inject } from "mobx-react"
import { AppState } from "../store/AppState"

export interface ITestContainerProps {
    appState?: AppState
}

@inject("appState")
export class TestContainer extends React.Component<ITestContainerProps, any> {

    public render() {
        const { children, appState } = this.props

        return (
            <div>
                {appState.greeting}
            </div>
        )
    }
}

谁能指出我遗漏了什么？

Answer 1

您要求注射器寻找名为 appState 的商店，但您给 Provider 的是一家名为 store 的商店。您似乎需要更改此行：

<Provider store={AppState}>

至：

<Provider appState={AppState}>

商店 'someStore' 不可用！确保它是由某些提供商提供的

Store 'someStore' is not available! Make sure it is provided by some Provider

typescript

reactjs

mobx-react
