したい事
- 某システムにおけるデイリーの画面ポチポチ作業を自動化したい
- 以前は Selenium で Firefox のドライバを使って動かしていた
- ところが Selenium さんは最近の Firefox と仲が悪いようで、Firefox ４８以降だと動かない（アプリが起動されるものの、指定したページへアクセスされない）※参考記事参照
- Firefox のバージョンを下げるのもアレだったので、Chrome に乗り換えた
TL;DR
以下の設定を追加して bundle install
Gemfile
gem "selenium-webdriver"
gem "pkg-config", "~> 1.1.7" #追加
gem "chromedriver-helper" #追加
~/.bundle/config
BUNDLE_BUILD__NOKOGIRI: "--use-system-libraries --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/libxml2"
あとは、driver 名を変えるだけ
pochipochi.rb
- @driver = Selenium::WebDriver.for :firefox
+ @driver = Selenium::WebDriver.for :chrome
ハマった所
とりあえず bundle install した結果
$ bundle install

IMPORTANT NOTICE:
Building Nokogiri with a packaged version of libxml2-2.9.4
with the following patches applied:
- 0001-Fix-comparison-with-root-node-in-xmlXPathCmpNodes.patch
- 0002-Fix-XPointer-paths-beginning-with-range-to.patch
- 0003-Disallow-namespace-nodes-in-XPointer-ranges.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.

An error occurred while installing nokogiri (1.8.0), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.8.0'` succeeds before bundling.
LZMA_OK がないとか何とか怒られる...
--use-system-libraries を追加してみた結果
$ bundle config build.nokogiri --use-system-libraries

完全に空振り。 libxml2 が相変わらず読めていない模様。
結論関係なかった。
よくよく最初のエラーを見てみると
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

なるほど、 bundle のオプションでパスを指定できるのね。
ちなみに
他の記事を見ていると
$ brew link --force libxml2
で解決！と書いてる人が何人かいたものの、 brew install libxml2 した時のメッセージがこんなん↓で
This formula is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.
If you need to have this software first in your PATH run:
echo 'export PATH="/usr/local/opt/libxml2/bin:$PATH"' >> ~/.bash_profile
For compilers to find this software you may need to set:
LDFLAGS: -L/usr/local/opt/libxml2/lib
CPPFLAGS: -I/usr/local/opt/libxml2/include
For pkg-config to find this software you may need to set:
PKG_CONFIG_PATH: /usr/local/opt/libxml2/lib/pkgconfig
link --force はちょっと不安が残ったので不採用。 ※この辺まだ良くわかってない
