What's Wrong?

brew install claude-code fails if Claude already installed - tried this with Claude installed natively and via brew.

==> Installing Cask claude-code
==> Purging files for version 2.0.76 of Cask claude-code
Error: It seems there is already a Binary at '/opt/homebrew/bin/claude'.

Trying brew install --force Claude recommended doesn't resolve that.

Claude is suitably embarrassed at diagnosing its own install problems ;-)

What Should Happen?

a) it works
b) failing that, its documented in troubleshooting guide
c) failing that, Claude's own advice to solve it works

Made it work using sudo mv /opt/homebrew/bin/claude /opt/homebrew/bin/claude-noncode, leaving this bug report here for folks who might want Claude but not know to do that
