TypeError:_this.store.getState在使用来自Redux的连接时不是函数

TypeError: _this.store.getState is not a function when using connect from Redux

本文关键字:Redux 连接 函数 this store getState TypeError      更新时间:2023-09-26

当我第一次使用node app.js运行服务器时,一切都很好,我得到了listening on 5050。然后我转到localhost:55050/,在服务器运行的控制台中收到这些警告。

Warning: Failed propType: Required prop `store.subscribe` was not specified in `Provider`.
Warning: Failed Context Types: Required child context `store.subscribe` was not specified in `Provider`. 

组件在那里表现得很好,但一旦我进入localhost:550/ballerviews,我就会在服务器上得到它

你可以在我的Github上查看整个项目,因为我觉得在那里查看它可以获得最好的理解。

我今天一整天都在想办法解决这个问题,但我做不到。在我尝试在服务器上渲染之前,它运行良好。我很感激你的帮助,如果你需要更多信息来回答这个问题,请告诉我。

只有两个小问题:

1.ES2015模块->CommonJS

您在src/store.js中使用的是ES2015 export default,但是您需要通过第11行app.js中的CommonJS使用它。

当然,这很好,但在需要时,您需要访问默认属性。更新行如下:

// Old
const store = require('./src/store.js')
// New
const store = require('./src/store.js').default

2.在服务器上调用document

src/components/BallerViews.jsx的第41行,您正在访问服务器上不存在的文档。一个快速的解决方案是将这条线包装在一个条件中:

// Old
document.body.style.backgroundColor = '#0e0e13'
// New
if (typeof document !== 'undefined') {
  document.body.style.backgroundColor = '#0e0e13'
}
