我注意到了......
当我运行“composer help update”它告诉我默认启用--dev选项
--dev Enables installation of require-dev packages (enabled by default, only present for sanity).
启用composer install的“--no-dev”命令不是这种情况，
--no-dev Disables installation of require-dev packages (enabled by default, only present for sanity).
所以，我想知道......
为什么update和install的默认行为对于开发者要求是不同的？
