如何安装Rails MySQL适配器? [英] How do I install the Rails MySQL adapter?

问题描述

我的问题仅此而已. gem install mysql不起作用，我没有通过谷歌搜索找到任何内容.

There's not much more to my question than that. gem install mysql doesn't work and I haven't found anything by Googling.

当我尝试gem install mysql2时，这就是我得到的.我不知道现在该怎么办.

When I try gem install mysql2, this is what I get. I don't know what to do now.

jason@buster:~/projects/mcif-rails$ gem install mysql2
Building native extensions.  This could take a while...

推荐答案

看来您仍然需要安装MySQL的开发库.这些是gem在系统上成功构建所必需的.

It looks like you still need to install MySQL's development libraries. These are required for the gem to build successfully on your system.

似乎RoR Wiki不再可用.但是，Ubuntu提供了他们自己的演练，该建议提示:

Seems the RoR Wiki is no longer available. But, Ubuntu has offered their own walkthrough which suggests:

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

参见 http://wiki.rubyonrails.org/database-support/mysql#installation了解更多信息.

See http://wiki.rubyonrails.org/database-support/mysql#installation for more detail.

示例:Ubuntu

sudo apt-get install mysql-server mysql-server-5.0 libmysqlclient15off \
    libmysqlclient15-dev mysql-client-5.0 mysql-common

sudo apt-get install libmysql++-dev

sudo gem install mysql
