在 Fedora 上安装 MySQL gem 时出现问题 [关闭]

Question

当我尝试 rake db:migrate 时，我收到以下错误：

The bundled mysql.rb driver has been removed from Rails 2.2.
Please install the mysql gem and try again: gem install mysql.
rake aborted! no such file to load -- mysql

当我尝试gem install mysql

Building native extensions. This could take a while... ERROR: Error installing
mysql: ERROR: Failed to build gem native extension. /usr/bin/ruby extconf.rb
Can't find header files for ruby. Gem files will remain installed in
/usr/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.

$ sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

也试过了，但同样的错误。我正在使用 Fedora 10。非常感谢您的帮助。干杯！

Answer 1

在安装 MySQL gem 之前，您需要安装用于 Ruby 和 MySQL 的 Fedora 开发包。试试：

$ sudo yum -y install gcc mysql-devel ruby-devel rubygems

然后重试您的：

$ sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

（还要检查 /usr/local/mysql/bin 是 mysql_config 的正确位置，它可能是 /usr/bin。）
