mariadb with rails:无法安装libmysqlclient-dev

Question

我在64位的Ubuntu 15:10上安装了mariadb-10.1。

我已经成功安装了libmysqlclient18，但在尝试安装libmysqlclient-dev时出现错误。

Answer 1

使用MariaDB时，必须安装libmariadbclient-dev而不是libmysqlclient-dev

sudo apt-get install libmariadbclient-dev

Answer 2

虽然安装libmariadbd-dev或libmariadbclient-dev包是最简单的方法，但在某些操作系统或包管理器中不可用。

例如，在装有自制软件的mac上，这是不可用的，但我找到了一个变通方法。

要在mac上安装gem连接器，您需要使用homebrew中的mariadb- mysql2 -c。此包与Mariadb符号链接冲突，因此您需要在终端中运行以下命令：

brew unlink mariadb
brew install mariadb-connector-c

在rails项目目录中，执行：bundle install (或gem install mysql2)

brew uninstall mariadb-connector-c
brew link mariadb
