运行Bundle Install或Gem Install Nokogiri时,我遇到了阻止我的应用程序运行的相同问题.我怀疑这个问题是本地的,并且来自将所有内容都移到Rails 5,但我不确定.这是错误消息：
An error occurred while installing nokogiri (1.8.1),and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.8.1'` succeeds before bundling.
In Gemfile:
rails_admin was resolved to 1.2.0,which depends on
rails was resolved to 5.1.3,which depends on
actioncable was resolved to 5.1.3,which depends on
actionpack was resolved to 5.1.3,which depends on
actionview was resolved to 5.1.3,which depends on
rails-dom-testing was resolved to 2.0.3,which depends on
nokogiri
(来自运行Bundle Install)
我已经尝试运行Bundle Update并使用Github推荐的各种Homebrew命令,但我没有取得任何成功.
gem install nokogiri -v’1.8.1′
1 error generated. make[2]: *** [xmlIO.lo] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 ======================================================================== *** extconf.rb Failed *** Could not create Makefile due to some reason,probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.
解决方法
Nokogiri无法正常构建,因为您没有像libxml2这样的开发库.查看日志文件以查看发生的情况或尝试使用brew install libxml2直接安装libxml2
