Homebrew and UPX Installation Procedure for macOS

homebrew.md

UPX detail : Compress/expand executable files;

Open terminal | Command+Space and type Terminal and press enter/return key.

Paste following code :

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null

Wait for the command to finish. After completion run following code :

brew install upx

When I enter the terminal code, it says "Need sudo access on macOS". I checked online, and apparently all it's needed is a "sudo" at the beginning of the code.
Still, after entering the password, it says "Don't run this as root! " , and if I enter the "brew install upx" code it will say "zsh: command not found: brew".

same problem here

brew install --build-from-source upx

There is an error in M1 mac.

Error: upx: no bottle available!
You can try to install from source with:
  brew install --build-from-source upx
Please note building from source is unsupported. You will encounter build
failures with some formulae. If you experience any issues please create pull
requests instead of asking for help on Homebrew's GitHub, Twitter or any other
official channels.

What should be done?

Any solution on this? Error: upx: no bottle available!

Well it didn't work with "brew install upx"

I did also get the message:
You can try to install from source with:
brew install --build-from-source upx

So that's what I did, I put in the terminal "brew install --build-from-source upx" and it works

Thanx for guiding me

M1芯片用这个命令可以：
arch -arm64 brew install --build-from-source upx

please help with this error
