我将Redmine应用程序v 2.5.0迁移到了Debian 9。复制所有文件后，将无法捆绑更新或安装。
我先安装了default-libmysqlclient-dev，然后安装了gem install mysql
但没有成功。
捆绑更新提供以下输出：
Your Gemfile lists the gem activerecord-jdbcmysql-adapter (>= 0) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of one of them later.

An error occurred while installing mysql (2.8.1), and Bundler cannot continue.
Make sure that `gem install mysql -v '2.8.1'` succeeds before bundling.
当我尝试安装捆绑软件时，出现与以下相同的错误：
An error occurred while installing json (1.8.1), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.1'` succeeds before bundling.
