的可能的複製[寶石安裝mysql失敗（HTTP做到這一點：/ /stackoverflow.com/questions/5795309/gem-install-mysql-fail） –

[gem install rails failed on ubuntu]可能重複（http://stackoverflow.com/questions/29317640/gem-install-rails-fails-在Ubuntu的） –

寶石在這種情況下需要3個包。

sudo apt-get install libnetcdf-dev libssl-dev libcrypto++-dev

這是MAC，但你需要改變的路徑：

gem uninstall mysql2

intall MariaDB的10.1 andnecesaary SSL包或者這也許不需要然後檢查路徑庫和tinal文件夾具有相同的名稱：

bundle config --local build.mysql2 "--with-mysql-config=/usr/local/Cellar/[email protected]/10.1.29/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include"

或無SSL路徑

bundle config --local build.mysql2 "--with-mysql-config=/usr/local/Cellar/[email protected]/10.1.29/bin/mysql_config

或直接的寶石，但是，如果你ffrom MySQL的是更好地與束

gem install mysql2 -v 'x.y.z' -- --with-mysql-config=/usr/local/Cellar/[email protected]/10.1.29/bin/mysql_config

最後

bundle install
