Drush不会在两台服务器中的任何一台上更新

Question

我有两个不同的Windows2016服务器运行Drupal8，都安装了Drush 9，但我有一个Drush版本不匹配，我试图修复。

我在两台服务器上都有这个全局composer.json文件：

{
    "require": {
        "drush/drush": "9.*"
    }
}

在我的测试服务器上，drush --version显示版本9.5.2。在我的Live服务器上，drush --version显示版本9.7.0。

如果我在我的测试服务器上运行composer global update drush/drush，它不会更新Drush，并返回"nothing to install or update“。

我试过这个：

composer global require drush/drush:9.7.0

并得到了这个错误：

Changed current directory to C:/Users/username/AppData/Roaming/Composer
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Can only install one of: consolidation/site-alias[3.0.0, 1.1.11].
    - Can only install one of: consolidation/site-alias[3.0.0, 1.1.11].
    - Can only install one of: consolidation/site-alias[3.0.0, 1.1.11].
    - drush/drush 9.7.0 requires consolidation/site-alias ^3.0.0@stable -> satisfiable by consolidation/site-alias[3.0.0].
    - Installation request for drush/drush 9.7.0 -> satisfiable by drush/drush[9.7.0].
    - Installation request for consolidation/site-alias (locked at 1.1.11) -> satisfiable by consolidation/site-alias[1.1.11].


Installation failed, reverting ./composer.json to its original content.

比较两种环境下composer.lock中的"name": "consolidation/site-alias",这一行，我看到Test1.1.11和Live3.0.0。

我安装了drupal/recommended project，并认为我在这两者上遵循了相同的步骤，所以我不确定它们是如何不同步的。有什么想法吗？

推荐的修复方法是什么？

Answer 1

我运行了composer require drush/drush，现在两者都在10.2.x版本上。
