Gem libxml-ruby(1.1.4)安装但在运行时失败

Question

我正在尝试在Mavericks上运行一个相当旧的Rails应用程序,其中一个要求是: - Ruby ree-1.8.7-2009.10 - Rails 3.0.0 - libxml-ruby 1.1.4(这是与其他版本兼容的最新版本)宝石

我安装了最新的libxml2包.它的版本来自Homebrew(2.9.1).

要安装此gem,我使用以下命令:

$ CC=gcc-4.2 gem install libxml-ruby -v '1.1.4'

输出建议成功:

Building native extensions.  This could take a while...
Successfully installed libxml-ruby-1.1.4
1 gem installed

虽然当我尝试运行一些rake任务时,即创建数据库bundle exec rake db:create

我收到以下错误:

$ bundle exec rake db:create                                                                                               [ree-1.8.7-2009.10@mygemset]

我尝试了很多可以在互联网上找到的方法(最相关的例子涉及安装Nokogiri的问题以及列出的类似错误),但没有一种方法有效.

Answer 1

可能以前的版本破坏了本机加载，或者您的 libxml2 太新并且不适合 gem 实现。

• 首先卸载所有以前的gem（宝石集，系统）
• 然后重新安装宝石
