php - Composer - 开发要求的默认选项

Question

我注意到...

当我运行' composer help update'它告诉我该--dev选项默认启用

 --dev  Enables installation of require-dev packages (enabled by default, only present for sanity).

composer install' ' 命令不是这种情况，在哪里--no-dev启用，

--no-dev Disables installation of require-dev packages (enabled by default, only present for sanity).

所以，我想知道...

为什么开发要求的默认行为update和install不同？

Answer 1

As noted in the release notes of the last release (alpha7), the install package will start defaulting to --dev as well in the near future. The reason they are not the same at the moment was to allow a transitional phase.
