一开始很抱歉，Stacksoverflow 只是不想理解，这也是代码。
是的，我知道这是非常糟糕的代码，很抱歉。
在：
Ittems.erase(Ittems.begin
您不调用 begin，您需要一对 ()，但将字符串文字添加到向量迭代器也没有任何意义，因此请重新考虑您的添加。
- "Little Pice Of Meat");
你可以这样处理这两种情况。
#...
#include <algorithm>
..# //include this library then
Ittems.erase(Ittems.begin + "Little Pice Of Meat");
我不知道你是想删除这个条目，还是基本上删除这个条目之前的所有元素，但无论如何，我假设你想删除这个元素。
使用：
auto dis = find(Ittems.begin(), Ittems.end(), "Little Pice Of Meat");
Ittems.erase(Ittems.begin() + std::distance(Ittems.begin(), dis)); //use
//distance to get the position of the element in the vector
或使用
Ittems.remove(Ittems.begin(), Ittems.end(), "Little Pice Of Meat");
