推荐答案

我们不能：错误意味着确切地说了什么。

We can't: the error means exactly what is says.

The variable insert is assigned but its value is never been used

你已声明 insert ，你已经给它一个初始值，但你不再在你的代码中使用它。

我们无法解决这个问题：我们不知道你的代码的其余部分是什么，或者变量应该适合的位置！

You have declared insert, you have given it an initial value, but you do not use it in your code again.
We can't fix that: we have no idea what the rest of your code does, or where the variable is supposed to fit in!
