标签: mysql ruby-on-rails rubygems ubuntu-10.04

我正在尝试安装mysql 2.8.1 gem。我将使用它在Ubuntu 10.04上构建Rails 2.0.2应用程序。我会使用Ruby 1.8.7。我已经安装了开发依赖项(其他宝石)。由于某些原因,我无法安装它。我无法弄清楚如何修复它。请帮忙!!

我尝试安装时在终端中收到以下内容:

mohnish@pc146724-desktop:~/Downloads$ sudo gem install mysql-2.8.1.gem

如果这还不够,请尝试这样

试试这个,然后安装mysql gem:

     

sudo apt-get install libmysqlclient-dev libmysqlclient16

这在运行sudo gem install mysql之后起作用。

文档仍然无法正确安装(大量的“无定义”错误,尽管这不是真正的大问题。

您应该执行错误消息告诉您的操作:检查mkmf.log!使用find /usr/lib/ruby/gems/1.8/gems/ -name mkmf.log搜索此文件。通常,出现此错误消息是因为您忘记为您尝试安装的扩展安装-dev软件包。所以如果你想安装mysql gem,你可能忘了先安装libmysqlclient14-dev。进行apt-cache搜索grep dev找到合适的包。

就我而言,我收到以下错误消息:

  

安装mysql(2.8.1)时发生错误,而Bundler不能   继续。确保gem install mysql -v '2.8.1'成功   在捆绑之前。

我试过:gem install mysql -v '2.8.1',我收到的错误信息类似于你得到的信息。

我修复了它,执行以下操作:

  • 步骤(1):运行:sudo apt-get install libmysqlclient-dev

  • 步骤(2):安装mysql:gem install mysql -v 2.8.1

您应该获得类似于此的成功消息:

  

成功安装mysql-2.8.1
安装ri文档   mysql-2.8.1 1 gem安装

我希望我的回答有所帮助。
