[q-b]

Please note that we will close your issue without comment if you delete, do not read or do not fill out the issue checklist below and provide ALL the requested information. If you repeatedly fail to use the issue template, we will block you from ever submitting issues to Homebrew again.

• are reporting a bug others will be able to reproduce and not asking a question. If you're not sure or want to ask a question do so on our Discourse: https://discourse.brew.sh
• ran a brew command and reproduced the problem with multiple formulae? If it's a problem with a single, official formula (not cask) please file this issue at Homebrew/homebrew-core: https://github.com/Homebrew/homebrew-core/issues/new/choose. If it's a brew cask problem please file this issue at https://github.com/Homebrew/homebrew-cask/issues/new/choose. If it's a tap (e.g. Homebrew/homebrew-php) problem please file this issue at the tap.
• ran brew update and can still reproduce the problem?
• ran brew doctor, fixed all issues and can still reproduce the problem?
• ran brew config and brew doctor and included their output with your issue?

What you were trying to do (and why)

Using homebrew after the Catalina upgrade ( macOS 10.15 (19A602) )

What happened (include command output)

The brew command traceback, including brew doctor and brew config, so I won't be able to paste their output here.

Command output

Traceback (most recent call last):

3: from /usr/local/Homebrew/Library/Homebrew/brew.rb:23:in <main>' 2: from /usr/local/Homebrew/Library/Homebrew/brew.rb:23:in require_relative'

1: from /usr/local/Homebrew/Library/Homebrew/global.rb:12:in <top (required)>' /usr/local/Homebrew/Library/Homebrew/global.rb:12:in require': cannot load such file -- active_support/core_ext/object/blank (LoadError)
  

Strangely, brew update works most of the time, but happens to traceback too.

What you expected to happen

Normal usage.

Step-by-step reproduction instructions (by running brew commands)

Run any one of those commands:

brew doctor
brew search vim
brew upgrade
...

Can you try running brew update-reset?

• If you're not sure or want to ask a question do so on our Discourse: https://discourse.brew.sh

This is not an issue everyone is experiencing so closing with assumption brew update-reset will fix things. Please take future similar issues to Discourse.

Thank you guys, I wasn't aware of the brew update-reset command but it fixed my issue.
I'll remember to try discourse first next time, sorry for wasting your time!

[MikeMcQuaid]

No worries @q-b, glad you got it sorted!

I've just hit the same issue after I upgraded Xcode on macOS Catalina 10.15.1 from 11.1 to 11.2. Running brew update-reset fixed the issue.

Just posting to state this is not an isolated incident and more people may be affected.

I also run into this issue once I executed brew cleanup some time after the upgrade from 10.14 to 10.15. brew update-reset fixed the problem for me as well.

I just hit this issue! Macosx Catalina 10.15 . Can't install homebrew !
