问题描述

我正在尝试在 ruby 2.3.1 上安装导轨.

I am trying to install rails on ruby 2.3.1.

$ ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]

安装了 Ruby.

$ rvm -v
rvm 1.26.11 (latest) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

RVM 存在.

$ gem install rails
Building native extensions.  This could take a while...
ERROR:  Error installing rails:
    ERROR: Failed to build gem native extension.
current directory: /usr/local/rvm/gems/ruby-2.3.1/gems/nokogiri-1.7.0.1/ext/nokogiri

Gem files will remain installed in /usr/local/rvm/gems/ruby-2.3.1/gems/nokogiri-1.7.0.1 for inspection.
Results logged to /usr/local/rvm/gems/ruby-2.3.1/extensions/x86_64-linux/2.3.0/nokogiri-1.7.0.1/gem_make.out

当我调用 gem list 时，我没有看到 nokogari 和 rails.$ 宝石列表

When I call gem list, I don't see nokogari nor rails. $ gem list

 *** LOCAL GEMS ***
...
minitest (5.8.3)

我不知道出了什么问题.

推荐答案

按照这里的说明(忽略日语，直接使用代码！http://qiita.com/riocampos/items/43b55ba06e6c3ec01b82

follow instruction here (ignore the japanes, just use the code!http://qiita.com/riocampos/items/43b55ba06e6c3ec01b82

$ brew update

$ brew install libxml2

$ brew link --force libxml2

$ gem install nokogiri -- --use-system-libraries

如果出现问题，请使用 sudo:

in case of problems use sudo:

sudo gem install nokogiri -- --use-system-libraries libxml2

猜测系统 10.2.3 使用了不兼容的 libxml2，因此强制链接到与 homebrew 一起安装的过时"libxml2 可以完成这项工作.

guess System 10.2.3 uses incompatible libxml2, so forced linking to the «outdated» libxml2 installed with homebrew does the job.
