We’re also getting reports of this issue on the cask taps.

This was caused by #4392.

@vitorgalvao Of a failure to remove formulae?

I did a search of Homebrew, Caskroom, and Cellar and found multiple occurrences of <<-EOS.undent. Doing a global search for .undent and removing it fixed the error for me.

clicked through to the merged PR (#4502) and saw a statement that the method was deprecated. The cask that's failing for me is kind of old - is deleting the directory (/usr/local/Caskroom/android-sdk for me) the recommended way for people to deal with this error now?

The error with Casks needs to have a separate issue. Feel free to open one @toejough or @onaforeignshore; no manual deletion should be required.

@toejough

wow, solid 👍 on the fast response. Unfortunately, I'm churning through a bunch of installation updates right now and didn't expect to hear back from anyone for a while, so I already nuked the directory - I can make an issue, but I won't be able to provide the standard debug data the issue template asks for.

@toejough
Copy link

wait! I've got other old casks I just hadn't run into. I'll file new issue :-)

@toejough

oh, well hold on - Homebrew/homebrew-cask#49716 (comment) was a Casks issue, and was closed citing this one. Should that one be re-opened?

@publicarray @toejough what's the deal with this issue? I just upgraded Homebrew and it doesn't work anymore.

@yegor256 Please be more specific or just subscribe to the issue, please.

I'm seeing same issue after a brew update:

[rwkelley@vector tools]$ brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/ec545d45d4512ace3570782283df4ecda6bb0044/Formula/python3.rb ######################################################################## 100.0% Error: python3: undefined method undent' for #String:0x0000000102127890`

@kelleyrw That's because you're trying to install an old, unsupported Git revision of Python 3. We will not and cannot fix that.

@kelleyrw

@MikeMcQuaid The error message doesn't look like an a python issue per se. It looks like a ruby issue and the same error is seen above by @reitermarkus.

I Understand that this is not an appropriate comment here on this thread but just an observation: Why no support older versions of python? I'm not seeing a python@3.5 for example. Doesn't it seem a bit risky to only support the latest version? Most production systems may be several version behind.

@MikeMcQuaid The error message doesn't look like an a python issue per se. It looks like a ruby issue and the same error is seen above by @reitermarkus.

@kelleyrw It is an issue with the fact you are trying to install a random revision of a formula from the Git history. This is not something we can fix or will fix. It's the same error because it's the same underlying cause: the method used in that formula was deprecated, disabled and now removed.

I Understand that this is not an appropriate comment here on this thread but just an observation: Why no support older versions of python? I'm not seeing a python@3.5 for example. Doesn't it seem a bit risky to only support the latest version? Most production systems may be several version behind.

Thank you for pointing this out.

For me, it's caused by mactex-no-ghostscript in .metadata.
Here's how to handle this issue in detail.

cd /usr/local/Caskroom     # or Cellar Homebrew
grep "<<-EOS.undent" -R .  # search the `undent` method
vim PATH_FROM_ABOVE        # locate the method and comment relative lines

@onaforeignshore thx.
