Question

我正在尝试运行一个ruby脚本，它基本上是一个调用ActiveMQ代理的Stomp客户端。

当我运行脚本时，我收到此错误：

going to startC:/Ruby22-x64/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:5
4:in `require': cannot load such file -- stomp (LoadError)
        from C:/Ruby22-x64/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54
:in `require'
        from C:/Users/lokesh.kumar/Documents/issues/ActiveMQ-slowness/activemq-c
acti-plugin.rb:34:in `<main>'

以下是命令gem env

的结果

我从未在Ruby工作过，所以这可能是一个基本的安装错误。有什么指针可以解决这个问题吗？

好像你没有安装NX gem 您可以使用argv[1]安装任何所需的宝石。

在您的特定情况下，#define _GNU_SOURCE #include <stdio.h> #include <unistd.h> #include <sys/syscall.h> void shellcode(void) { static char buf[] = "shellcode: hello\n"; char *cp; for (cp = buf; *cp != 0; ++cp); // NOTE: in real shell code, we couldn't rely on using this function, so // these would need to be the CPP macro versions: _syscall3 and _syscall2 // respectively or the syscall function would need to be _statically_ // linked in syscall(SYS_write,1,buf,cp - buf); syscall(SYS_exit,0); } int main(int argc,char **argv) { void *retadr = __builtin_return_address(0); void **fp = __builtin_frame_address(0); int iter; printf("retadr=%p\n",retadr); printf("fp=%p\n",fp); // NOTE: for your example, replace: // *fp = (void *) shellcode; // with: // *fp = (void *) argv[1] for (iter = 20; iter > 0; --iter, fp += 1) { printf("fp=%p %p\n",fp,*fp); if (*fp == retadr) { *fp = (void *) shellcode; break; } } if (iter <= 0) printf("main: no match\n"); return 0; }为stomp 因此，请尝试运行gem install GEMNAME并再次运行您的脚本。

P.S。
默认情况下，GEMNAME命令使用rubygems作为宝石源因此，您可以随时查看宝石名称。
