操作系统 Ubuntu 12.04。我已经从https://github.com/rails/rails.git克隆了 rails4.0.0beta1 。我有 ruby​​ 2.0.0p0（2013-02-24 修订版 39474），当我尝试执行“捆绑安装”时，我收到以下错误消息：

Gem files will remain installed in /home/zergood/.rvm/gems/ruby-2.0.0-p0/gems/mysql-2.9.1 for inspection.
Results logged to /home/zergood/.rvm/gems/ruby-2.0.0-p0/gems/mysql-2.9.1/ext/mysql_api/gem_make.out

An error occurred while installing mysql (2.9.1), and Bundler cannot continue.
Make sure that `gem install mysql -v '2.9.1'` succeeds before bundling.

我该如何解决？

所以，尝试类似的东西

sudo apt-get install libmysql-ruby libmysqlclient-dev mysql-server \
mysql-client mysql-common

进而

gem install mysql

我有一个非常相似的问题 -使用 ruby​​ 2.0但在 Mac 10.9.2 上安装Mysql 2.9.1 错误

解决方案在这里找到：https ://stackoverflow.com/a/4115182/775359

brew install mysql

您需要 mysql2 的 MySQL 开发头文件才能正确编译。这是必需的，因为大部分功能是用 C 语言编写的，随后与 MySQL 相关联。

只是一个小的更正：libmysql-ruby 正在逐步淘汰，所以ruby-mysql改用 --> https://askubuntu.com/questions/641943/e-unable-to-locate-package-libmysql-ruby

因此完整的命令是：

sudo apt-get install ruby-mysql libmysqlclient-dev mysql-server \ mysql-client mysql-common

进而

gem install mysql
