export PATH=~/.composer/vendor/bin:$PATH）。composer.json（默认位于 ~/.composer/composer.json）中添加 "minimum-stability": "dev"。composer global require 'dominik/bleed=dev-master'

composer global update 'dominik/bleed'
作为你的律师，我建议你不要使用本软件从事在你所在地区适用法律下不合法的事情，无论你用它做什么。打个比方：在你自己的后院开车碾压东西可能是允许的，但在大多数司法管辖区，在街上碾压东西很可能是违法的。
