Railsがインストール出来ない←nokogiriがインストールできない←libxml2がない←liblzma.dylibがない←あるんだけど…←中身がなかった

これと同じエラーがでたqiita.com

依存関係をインストール

brew install libxml2

が、だめ…っ!

sudo gem install nokogiri

むかしのが関係してるのかなとアンインストールしたけどいみがなかった

sudo gem uninstall -i /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/gems/2.0.0 nokogiri

withなんちゃらをつけてみた

sudo gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2

************************************************************************
IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.2
with the following patches applied:
- 0001-Revert-Missing-initialization-for-the-catalog-module.patch
- 0002-Fix-missing-entities-after-CVE-2014-3660-fix.patch

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

gem install nokogiri -- --use-system-libraries
[--with-xml2-config=/path/to/xml2-config]
[--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

bundle config build.nokogiri --use-system-libraries
bundle install

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

liblzma.dylibがないよとか言われる

not found "/usr/local/lib/liblzma.dylib"みたいなエラー
ls /usr/local/lib/liblzma.dylibしてもある

調査

cat /usr/local/lib/liblzma.dylib

_人人人人人人人人_
> なかみがない <
 ̄Y^Y^Y^Y^Y^Y^Y ̄

liblzmaをインストール

brew install xz
rm -rf /usr/local/Cellar/xz/5.0.3
brew link --force xz

これでインストールできるようになった(`・ω・´)

sudo gem install nokogiri
sudo gem install rails
