homebrewで入れた[email protected]とmysql2 gemを動かす
MojaveにUpgradeしたりmysqlをダウングレードしたりしてたら動かなくなったので修正メモ
環境
macOS Mojave 10.14
mysql 5.6.42
結論
❯ bundle exec gem uninstall mysql2
❯ bundle config --local build.mysql2 --with-mysql-config=/usr/local/opt/[email protected]/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include
❯ bundle install
※ 2019/09/11 追記
フラグが2つあるとうまく動かない場合もあるらしい。
bundle install 時、mysql2でエラー - Qiita
その場合は片方のflagだけで良さそう。
❯ bundle config --local build.mysql2 --with-mysql-config=/usr/local/opt/[email protected]/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl/lib
❯ bundle install
試行錯誤の道のり
❯ bundle exec rake db:create
rake aborted!

The Gemfile's dependencies are satisfied
The following gems are missing OS dependencies:
* mysql2: /usr/local/opt/mysql/lib/libmysqlclient.20.dylib
ふむふむ。
入れ直してみるか。
❯ bundle exec gem uninstall mysql2
Successfully uninstalled mysql2-0.4.10

Make sure that `gem install mysql2 -v '0.4.10'` succeeds before bundling.

mysql-configに[email protected]
のものを指定してみて再度チャレンジ。
❯ bundle config build.mysql2 --with-mysql-config=/usr/local/opt/[email protected]/bin/mysql_config
❯ bundle install

Don't know how to set rpath on your system, if MySQL libraries are not in path mysql2 may not load
