我正在尝试安装MySQL2.8.1 gem。我将使用它在Ubuntu 10.04上构建一个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gem)。由于某些原因,我无法安装它。我不能准确地想出如何修复它。请帮帮我!!
当我尝试安装它时,我在终端中得到以下信息:
mohnish@pc146724-desktop:~/Downloads$ sudo gem install mysql-2.8.1.gem

试着这样做,然后安装mysql gem:
sudo apt-get install libmysqlclient-dev
如果这还不够,试着这样做
sudo apt-get install libmysqlclient-dev libmysqlclient16 ruby-dev

您应该按照错误消息告诉您的那样做: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了为您试图安装的扩展安装-dev包。因此,如果您想安装mysql gem,您可能忘记了首先安装libmysqlclient14-dev。执行apt-cache搜索| grep dev以查找适当的包。
