在Ubuntu上安装mysql gem的困难
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。我将使用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。我无法准确地找出如何修复它。请帮忙 当我尝试安装终端时,我在终端中获得以下信息:在Ubuntu上安装mysql gem的困难,mysql,ruby-on-rails,rubygems,ubuntu-10.04,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。我将使用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。我无法准确地找出如何修复它。请帮忙 当我尝试安装终端时,我在终端中获得以下信息: mohnish@pc146724-desktop:~/Downloads$ sudo gem install mysql-2.8.1.gem Building native extensions.

谢谢你的帮助 试试这个,然后安装mysql gem:
sudo apt-get install libmysqlclient-dev
如果这还不够,就这样试试
sudo apt-get install libmysqlclient-dev libmysqlclient16 ruby-dev
您应该按照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尝试安装的扩展安装-dev包。因此,如果您想安装mysql gem,可能忘了先安装libmysqlclient14 dev。执行apt缓存搜索| grep dev以查找适当的包 请查看更多信息
尝试此操作,然后安装mysql gem:
sudo apt-get install libmysqlclient-dev
sudo apt get安装libmysqlclient dev libmysqlclient16
这在运行sudogem安装mysql之后就起作用了
文档仍然没有正确安装(大量的“无定义”错误,尽管这不是什么大问题。在我的例子中,我收到了以下错误消息: 安装mysql(2.8.1)时出错,Bundler无法运行 继续。确保
gem安装mysql-v'2.8.1'
成功
捆扎前
我尝试了:gem安装mysql-v'2.8.1'
,我得到了一条与您得到的类似的错误消息
我通过以下操作修复了它:
- 步骤(1):运行以下命令:
sudo apt get install libmysqlclient dev
- 步骤(2):安装mysql:
gem安装mysql-v2.8.1
安装的ri文档 mysql-2.8.1安装了1个gem
我希望我的回答能有所帮助。ruby开发包在这里是可选的,对我来说是可行的,但我根本不需要安装
libmysqlclient*
sudo apt get install libmysqlclient dev libmysqlclient18
对我来说是可行的,只需要安装libmysqlclient
