用composer安装alpha dev版本

Question

块类模块有一个8.x-1.x-dev版本。使用特定发布页中推荐的命令安装

composer require 'drupal/block_class:1.x-dev'

安装一个无版本的block_class。

这是为什么，对未来的composer update意味着什么？

更新:使用drush安装时

drush dl block_class --select 

并选择最新的开发版本，该版本是1.0-alpha1+10-dev，如何安装最新的alpha-dev？

Answer 1

正如我所说的，只要不指定版本，composer就会自动选择安装最稳定版本的版本约束：

$ composer require drupal/block_class
Using version ^1.0@alpha for drupal/block_class
./composer.json has been updated
