Cannot seem to update Homebrew to newer version so I can follow along w/ tutorials and install/update command line tools, Xcode etc.
Any help appreciated thank you!
Are you able to run brew doctor? If so, does it give you any guidance?
Can you cut/paste that full error message from your terminal into the text box (instead of a photo)? Googling errors can be a quick strategy for this sort of issue. I’ll dig into it and see what I find.

Looking at StackOverflow, some people have solved this by running brew update-reset. Try that, then another 'brew doctor` and see if anything changes.
Ok I thought maybe brew update-reset would fix the issue too just now but still shows after running brew doctor again. It looks like I may have a different Homebrew tap from an old command line program that I had which modified something?

It could be an issue with Ruby. It looks like something is requiring the activesupport gem, and it can’t find it.
Ok I have been trying to gem install activesupport but now it keeps saying I don’t have write permissions for gem directory?? thanks for your help so far
