我想我发现了问题 -
当我使用以下来源的 CS50 文件时，它不起作用：libcs50
但是当我从这里使用它时，编译是可能没有错误的： https://github.com/cs50/libcs50/releases
现在我还有其他问题，因为编译的EXE文件需要两分多钟才能启动，但我会将其放在另一个问题中，这样就更清楚了。
我将代码更改为并更新了最新的 cs50.c 和 cs50.h。文件：
#include "cs50.h"
#include <stdio.h>
int main(void)
{
string name = get_string("What is your name?\n");
printf("hello, %s\n", name);
}
然后我再次执行命令：
gcc string.c cs50.c
现在我收到这个巨大的错误消息：

最初的问题：
我现在遇到了与之前问题中所述相同的问题，但所描述的解决方案在我的情况下仍然不起作用： 如何在 Windows 上的 GCC 中链接 CS50 C 库
这是我的代码：
#include <cs50.h>
#include <stdio.h>
int main(void)
{
string name = <get_string("What is your name?\n");
printf("hello, %s\n" , name);
}
所以我尝试像这样编译程序：
gcc string.c cs50.c
这是我得到的错误：
string.c:1:10: fatal error: cs50.h: No such file or directory
#include <cs50.h>
我也尝试过在包含语句中使用“”而不是<>：
#include "cs50.h"
#include "stdio.h"
int main(void)
{
string name = get_string("What is your name?\n");
printf("hello, %s\n" , name);
}
然后我收到此错误消息：
string.c: In function 'main':
string.c:6:19: warning: implicit declaration of function 'get_string'; did you m
ean 'GetString'? [-Wimplicit-function-declaration]
string name = get_string("What is your name?\n");
^~~~~~~~~~
GetString
string.c:6:19: warning: initialization of 'string' {aka 'char *'} from 'int' mak
es pointer from integer without a cast [-Wint-conversion]

我该如何解决这个问题？
