I also have a solution:

homebrew.sh

Once you install Homebrew running brew commands doesn't require sudo or administrator rights for the user.

I have been fighting this fot a day now. Your script solved all my problems. Thanks

@honestpuck

Thanks for great script, but then in install via JAMF self service and after I try to install something with brew I get this, is it expected behaviour or I'm doing something wrong:

brew install midnight-commander
Error: The following directories are not writable by your user:
/usr/local/share
/usr/local/share/man
/usr/local/share/man/man1
/usr/local/share/zsh
/usr/local/share/zsh/site-functions

You should change the ownership of these directories to your user.
  sudo chown -R $(whoami) /usr/local/share /usr/local/share/man /usr/local/share/man/man1 /usr/local/share/zsh /usr/local/share/zsh/site-functions

And make sure that your user has write permission.

@Rokas When you're running a script from Jamf it's running as root, and I expect Homebrew installed via @honestpuck's script needs installs to be done from the logged in user's account. See this article on how you can do that: https://scriptingosx.com/2020/08/running-a-command-as-another-user/

@sdagley script already contains parts to run as user and it installs brew on user level successfully, just doesn't change some directory permissions for some reason..

So I'm able to install Homebrew, and can do installs, however, since the user is not an admin, when I get prompted at the end of the process to enter password to move the app to the /Applications folder, it fails. There a way around this?

I found a part of a script which might help you installing brew with jamf:

@CreativeB, AutoBrew can take care of all of this for you 🙂 

@kenny_botelho thank you for this script.  It saved me a bunch of time and work.

I found a script from @honestpuck which helped me a lot as well: 

https://github.com/Honestpuck/homebrew.sh 

here you have the installation of homebrew for Intel & M1 and installation scripts for brews and casks as well. All you need is to define $4 as package you want in your policy. 

Glad you found it useful. Always open to bug reports and suggestions for improvement.

When I run the script (homebrew-3.3.sh) in Jamf and try to install, it hangs and never seems to finish.  I run a script, before homebrew-3.3.sh, that installs Xcode and that does successfull complete... Terminal just gets stuck at "Running script Homebrew3.3.sh..."

Any advice on how to get passed this?  

Is there a active user session? Do you have mobile accounts or local users? Which kind of machine are you running this script on? 
I’ll try the updated version later - If I encounter the same issue as you, we might dive deeper into the code to fix it. 
as for the moment I posted in this thread, everything worked like charm for me. 

I am using a test mac with full admin rights to test.  Local users.  I am in the middle of formatting back to Catalina but I was testing this on BS 11.5 and Catalina and this issue occurred.

I am going to try install Xcode in a separate policy before running Homebrew script

Could you please try to run the script locally on a machine with “sh -x ./path/to/script.sh “ ? Maybe you find something. 
also it takes a while till it’s installed completely. 

@jlombardo, have you tired AutoBrew ?

@Rokas 

I'm assuming this is an Intel Mac, which OS are you running? Have you had a look at the log for when the policy ran the homebrew install script? Are you attempting the midnight-commander install from a policy or the command line?

@Jason33 

It's not possible to install scripts into /Applications via Homebrew if the user is not an admin. You should package the application and install it via Jamf. This is not a limitation of any script to install Homebrew but built in to the Apple security.

Sorry putting out backup and emergency patch fires, I will look into this and follow up.

This could be a silly question, but is there a way to have the end user fill the variable when running the brew-install-program.sh and brew-install-cask.sh scripts?

The user can run `brew install <software>` or `brew cask install <software>` from the command line. `brew-install-program.sh` is for when you want to do it from a policy.

The first thing we would need to know to fix this is what does the log say? What appears in the Jamf policy log? What is in `/private/var/log/Homebrew.log`?

The issue that our end users are experiencing is that they are prompted for admin credentials when they run `brew install <software>` or `brew cask install <software>`.

I could be overthinking the process, but I was thinking we could implement a policy containing `brew-install-program.sh` where the end user would simply input the program they want to install and it would populate the program into the script. Hopefully that makes sense.
