当调用createStore（）时，我得到：TypeError：中间件不是函数

Question

在标记之前有重复的注释，我已经检查过了：

我正在尝试集成set nocount on; declare @bill table (account_no tinyint, bill_cycle date); insert @bill (account_no, bill_cycle) values (1, '20190531'), (1, '20190430'), (2, '20190215'), (1, '20190531'); -- notice the duplicate for <1, May 31> declare @notrun table (account_no tinyint, bill_cycle date); insert @notrun (account_no, bill_cycle) values (1, '20190430'), (1, '20190630'), (1, '20190430'); -- notice the duplicate for <1, Apr 30> select account_no, bill_cycle from @bill except select account_no, bill_cycle from @notrun ; select bl.account_no, bl.bill_cycle from @bill as bl left join @notrun as nr on bl.account_no = nr.account_no and bl.bill_cycle = nr.bill_cycle where nr.account_no is null order by bl.account_no, bl.bill_cycle ; 并同时在Redux存储上使用替换redux-thunk。

基本上，我在某个地方：

replaceReducer

后来：

const {createStore, applyMiddleware} = require('redux');
const thunk = require('redux-thunk');
createStore(function() {return {}}, applyMiddleware(thunk));
// also tried
// createStore(function() {return {}}, {}, applyMiddleware(thunk));

现在，我在store.replaceReducer(someCombinedReducer); 行中触发了一个错误（因此，在更换任何减速器之前）。

createStore()

---

版本：

• redux：4.0.1
• redux-thunk：2.3.0

编辑：

直接在我进行的调用中，堆栈跟踪指向TypeError: middleware is not a function 函数，正像在此问题TypeError: middleware is not a function中一样。

经过一夜的睡眠和一些调整。

replaceAll()

应替换为：

// thunk here is not undefined but and object
const thunk = require('redux-thunk');
