Same here, after upgrade to xcode10.

@PureWhiteWu can we see your brew config output?

[MikeMcQuaid]

@PureWhiteWu Same question to you: did you upgrade to Xcode 10 recently?

[MikeMcQuaid]

@mlevin2 @PureWhiteWu FYI rm "$(brew --cache)/linkage.db" will temporarily resolve your issue. Please stick around and answer questions, though, I'd love to figure this out.

[PureWhiteWu]

@MikeMcQuaid Yes, I upgraded to Xcode 10 this morning.

[PureWhiteWu]

@MikeMcQuaid Thanks! But this seems not to help.

$ rm "$(brew --cache)/linkage.db"
rm: /Users/daniel/Library/Caches/Homebrew/linkage.db: No such file or directory

[MikeMcQuaid]

@PureWhiteWu Try to rm -rf /usr/local/Homebrew/Library/Homebrew/vendor/portable-ruby.

[resistor4u]

FWIW, my crashlog and config is here.

[MikeMcQuaid]

@resistor4u and @mlevin2 (and anyone else who reads this): please upload your $(brew --cache)/linkage.db somewhere I can download it and then you can remove it with $(brew --cache)/linkage.db which should fix your issue. That'll help me fix it for other people. Thanks!

@MikeMcQuaid hi, this helps, thanks!
If there's anything I can help, feel free to ask me.
