add --force to brew tap homebrew/core

[Qhilm]

if --force is omitted, the following error is seen:

$ brew tap homebrew/core
Error: Tapping homebrew/core is no longer typically necessary.
Add --force if you are sure you need it done.

Did you follow the previous step?

first set HOMEBREW_NO_INSTALL_FROM_API=1 in your shell environment

The conditional for this message should check that first making --force unnecessary:

brew/Library/Homebrew/tap.rb

Lines 321 to 323 in 2cb8efc

	elsif (core_tap? || core_cask_tap?) && !Homebrew::EnvConfig.no_install_from_api? && !force
	odie "Tapping #{name} is no longer typically necessary.\n" \
	"Add #{Formatter.option("--force")} if you are sure you need it done."

Maybe I should have been clearer in my original comment:

I followed the guide properly and properly set HOMEBREW_NO_INSTALL_FROM_API=1. I nevertheless get the above mentioned error.

I followed the guide properly and properly set HOMEBREW_NO_INSTALL_FROM_API=1. I nevertheless get the above mentioned error.

I tried to reproduce locally but was unable to. Only can see warning when HOMEBREW_NO_INSTALL_FROM_API is unset.

Can't see any warning when export HOMEBREW_NO_INSTALL_FROM_API=1 before brew tap homebrew/core or HOMEBREW_NO_INSTALL_FROM_API=1 brew tap homebrew/core, e.g.

$ brew tap homebrew/core
Error: Tapping homebrew/core is no longer typically necessary.
Add --force if you are sure you need it done.

$ export HOMEBREW_NO_INSTALL_FROM_API=1; brew tap homebrew/core

$ unset HOMEBREW_NO_INSTALL_FROM_API

$ brew tap homebrew/core

Something is different on my machine it seems:

[20:50]:HOMEBREW_NO_INSTALL_FROM_API=1; brew tap homebrew/core
Error: Tapping homebrew/core is no longer typically necessary.
Add --force if you are sure you need it done.

Is there a debug mode I can turn on?

It looks like you are setting a local variable. A semi-colon (;) is the same as two separate commands just on one line.

As docs mention, you need to modify your shell environment instead, which means you should be using an environment variable.

sorry, my mistake indeed. I misunderstood what "shell environment" meant here.
