为什么vector::erase不能在具有const的类元素上工作

#include <iostream>
#include <vector>

class MyClass {
public:
    MyClass(int val) : m_val(val) {}
    int getValue() const { return m_val; }

private:
    int m_val;
};

int main() {
    std::vector<MyClass> vec;
    vec.emplace_back(1);
    vec.emplace_back(2);
    vec.emplace_back(3);

    int target = 2;
    for (auto it = vec.begin(); it != vec.end(); ) {
        if (it->getValue() == target) {
            it = vec.erase(it);
        } else {
            ++it;
        }
    }

    for (const auto& elem : vec) {
        std::cout << elem.getValue() << " ";
    }
    std::cout << std::endl;

    return 0;
}
