path没有pop back成员

对不起,我的信息有误。实际上,在C++标准库的`std::filesystem::path`类中,并没有提供直接的`pop_back()`方法。`std::filesystem::path`是一个用于处理路径的对象,它的操作更倾向于基于方法链(method chaining)而非像数组那样可以直接访问元素。如果你想从路径中移除最后一个元素,你应该使用`remove_last()`方法。如果想返回上一级目录,可以使用`parent_path()`方法。
以下是纠正后的代码示例:
```cpp
#include <iostream>
#include <filesystem>
int main() {
std::string currentPath = __FILE__;
auto path = std::filesystem::path(currentPath);
// 移除最后一个元素(通常是文件名)
path.remove_last();
// 如果还有剩余部分,说明是在 Release/x64 中
if (!path.empty() && path.stem() == "Release" && path.parent_path().stem() == "x64") {
std::cout << "Found the 'Release/x64' directory." << std::endl;
} else {
std::cout << "Not in the 'Release/x64' directory." << std::endl;
}
return 0;
}
```
在这个例子中,我们使用了`remove_last()`来移除最后一个元素,然后检查剩下的部分是否表示"Release/x64"。
