Answer 1

我的案子的解决办法是.

composer global update
composer global require drush/drush:dev-master

以前，我一直在运行composer update，但需要运行composer global update。

Answer 2

假设这是一个Drupal 8问题；推荐的钻孔安装方法现在要将其安装为项目的依赖项，而不是系统应用程序。

composer require drush/drush

当然，这将安装Drush 9。如果出于某种原因，您需要8个然后是其他方法。但是，为了升级Drush，真的不必让sysadmin参与进来，这是一种解脱。
