求解 不进入root 装不了 这个软件？

luo@luo-desktop:/usr/local/3delight-8.0.1/Linux-x86_64/examples/opacity$ shaderdl fonky.sl
fonky.sl: in function fonky
fonky.sl:5: WARNING: initializing point 'amp' with a normal
fonky.sl:6: WARNING: addition should be performed on vectors, not points
ERROR: cannot open './fonky.sdl' for code generation (system error: Permission denied)
Compilation of 'fonky.sl' aborted due to errors: 1 errors, 2 warnings.

luo@luo-desktop:/usr/local/3delight-8.0.1/Linux-x86_64/examples/opacity$ sudo shaderdl fonky.sl
[sudo] password for luo:
sudo: shaderdl: command not found


不加 sudo 时 提示没有权限
加 了sudo后 提示没有这个命令！
是不是就必须进root阿？
可我不知道如何进去
