Mac OSx installing ERROR

[PicMicroKid]

I have tried to install on macOS Big Sur 11.6 and I got the error message below:

installer.sh: line 32: [/Applications/Xcode.app/Contents/Developer=/Applications/Xcode.app/Contents/Developer]: No such file or directory
ERROR: No Xcode Instalation found.
Please install Xcode and continue with this script

I have done many things:

• reinstalled Xcode,
• sudo xcode-select -switch ....
• sudo xcode-select --reset
  has not work.

I have changed the if [xcode-select -p="/Applications/Xcode.app/Contents/Developer"]; as if [xcode-select -p == "/Applications/Xcode.app/Contents/Developer"]; in the installer.sh file but did not work.
