二、xapian-full-1.2.3安装报错信息 #

current directory: /usr/local/rvm/gems/ruby-2.3.7/gems/xapian-full-1.2.3
/usr/local/rvm/rubies/ruby-2.3.7/bin/ruby -rrubygems /usr/local/rvm/rubies/ruby-2.3.7/lib/ruby/gems/2.3.0/gems/rake-10.4.2/bin/rake RUBYARCHDIR\=/usr/local/rvm/gems/ruby-2.3.7/extensions/x86_64-linux/2.3.0/xapian-full-1.2.3 RUBYLIBDIR\=/usr/local/rvm/gems/ruby-2.3.7/extensions/x86_64-linux/2.3.0/xapian-full-1.2.3

rake failed, exit code 1

三、当前环境信息 #

• Ruby版本：ruby 2.3.7p456 (2018-03-28 revision 63024) [x86_64-linux]

四、解决方案 #

1. 修复xapian-full-1.2.3安装的Config错误 #

xapian-full-1.2.3的Rakefile使用了废弃的Config常量，Ruby 2.3+需替换为RbConfig，步骤如下：

• 下载gem源码包：gem fetch xapian-full -v 1.2.3
• 解压源码：gem unpack xapian-full-1.2.3.gem
• 进入解压目录：cd xapian-full-1.2.3
• 编辑Rakefile，将第2行的Config替换为RbConfig
• 重新构建并安装gem：gem build xapian-full.gemspec && gem install xapian-full-1.2.3.gem

2. 安装系统级Xapian依赖 #

确保系统安装了Xapian开发库，否则gem编译会失败：
sudo apt-get install libxapian-dev

3. 解决Nokogiri与LibXML版本不匹配 #

重新安装Nokogiri并指定使用系统LibXML库：
bundle config build.nokogiri --use-system-libraries && bundle install

4. 处理git仓库警告（可选） #

如果应用依赖git仓库上下文，切换到项目的git根目录，或初始化仓库（仅当确实需要时操作）：
git init
