我一直在尝试在radare2 中调试二进制文件，但它向我抛出了这个错误。

$ r2 -d bin                      
Killing child process 1688 due to an error
Killing child process 1689 due to an error
[w] Cannot open 'dbg://./bin' for writing.

所以我在没有 -d 参数的情况下运行它，但我无法执行程序，dc如下所示

[0x00000610]> dc
Cannot continue, run ood?

我尝试运行ood但收到以下提示

[0x00000610]> ood
Killing child process 1711 due to an error
Killing child process 1712 due to an error
r_core_file_reopen: Cannot reopen file: dbg:///home/kali/Downloads/bin  with perms 0x7, attempting to open read-only.

这是二进制文件的问题还是我做错了什么？一些帮助表示赞赏。
