当尝试在一个 `std::string_view` 对象上调用 `.c_str()` 时，编译器会报错：`no member named 'c_str' in 'std::string_view'`。这是标准库对类型安全的保护机制，防止误用未保证的接口。 ### 解决方案 要修复这...

was not declare in this scope
10-20
"was not declared in this scope"是一个编译错误，通常是由于变量、函数或类未声明或定义导致的。另外，头文件相互包含时也可能导致依赖关系错误。例如，头文件形成了一个环形依赖，其中一个头文件中的#include语句将失去效果。还有一种情况是，当给头文件起名字时不小心与某个库中的头文件重名，而在程序中又使用了这个库的头文件，导致宏重名，自己写的头文件就失去了效果。这些情况都可能导致编译器无法找到声明，从而出现"was not declared in this scope"错误。
