Checksum mismatch for boot compiler of Crystal 0.10.0 about homebrew-crystal HOT 4 CLOSED

Strange, I tried this:

$ wget https://github.com/manastech/crystal/releases/download/0.9.1/crystal-0.9.1-1-darwin-x86_64.tar.gz
$ shasum -a 256 crystal-0.9.1-1-darwin-x86_64.tar.gz
1103edbb5d1ccb9555ce81d2b3630e7fbde93a75b2e368433859de0e4dc2717e  crystal-0.9.1-1-darwin-x86_64.tar.gz

so the shasum seems to be correct. I also tried installing the formula locally and it worked.If you do that wget/shasum steps manually, do you get a different shasum?

OK, I'll try it tonight.

Homebrew caches package to /Library/Caches/Homebrew, and on upgrading package, Homebrew uses the cache if available. It may cause this problem.
Anyway, I'll try it tonight.

After removing /Library/Caches/Homebrew/*, crystal-lang can be upgraded successfully. I'll close this issue because I understood the cause and how to avoid it.
