Composer使用時にSignal "5"が出る場合の対処方
[Symfony\Component\Process\Exception\RuntimeException]
The process has been signaled with signal "5".
brew upgrade svn
Upgrading from a 1.7 version built with this patch is not supported.
You should stay on 1.7, install 1.7 from homebrew-versions, or
brew rm subversion && brew install subversion
to build a new version of 1.8 without this patch.
と言われたら、
brew rm subversion && brew install subversion
これで、エラーが出なくなる。
