Issue with shellcode compiler

[elluelelf]

Hi, thank you so much for sharing the repo.
I have an issue with generating a reverse shell with msfvenom using the shellcode compiler. The compiler shows this syntax error regardless I respond with 'y' or 'n'.
May I know how can I fix this?

issue solved by giving the file execution permission then open it.
I can now run the compiler, thx.
