背景
git clone して開発をするとき、cloneしたあと bundle install のコマンドをターミナルに入力するとnokogiriのエラーに当たった。。。
解決までの備忘録として載せます。
開発環境
- mac OC : Mojava
- バージョン : 10.14.1
- ruby : 2.3.1
- rails : 4.2.1
- mysql : Ver 14.14 Distrib 5.6.42
コマンドとエラー文
※文中に出てくる、ターミナル内でのusernameは下記では[user_name]と記載しています。
例） ユーザーの名前がyamada-taroさんだった場合…
$ Users/yamada-taro/
↓
$ Users/[user_name]/ としています
1. bundle install する
すると下記のエラー文が出てきた

An error occurred while installing nokogiri (1.6.6.2), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.6.6.2' --source 'https://rubygems.org/'`
succeeds before bundling.
In Gemfile:
rails was resolved to 4.2.1, which depends on
actionmailer was resolved to 4.2.1, which depends on
actionpack was resolved to 4.2.1, which depends on
actionview was resolved to 4.2.1, which depends on
rails-dom-testing was resolved to 1.0.6, which depends on
nokogiri
gem install nokogiri -v '1.6.6.2' しなさいと言われてるので、その通りにしても同じエラーになる。。。
2. あらかじめあるGemfile.lockを削除する
git clone してきたファイルにあらかじめ設置されていたGemfile.lockがあるので、Gemfile.lockのファイルそのものを削除する
3. bundle update する
エラー文が変わった(・o・)

4. bundlerの構成オプションを設定して下記のコマンドを入力
$ bundle config --local build.mysql2 --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include
5. OpenSSLを入れる
$ brew install openssl
Warning: openssl 1.0.2p is already installed and up-to-date
To reinstall 1.0.2p, run `brew reinstall openssl`
6. reinstall しろと言われるのでその通りにする
$ brew reinstall openssl
