ruby-on-rails - 在linux上安装mysql2 gem

Question

我正在尝试在 linux 上安装 gem，但它给了我一个错误：

An error occured while installing mysql2 (0.3.11), and Bundler cannot continue.
Make sure that gem install mysql2 -v '0.3.11' succeeds before bundling.

我现在需要做什么？

Answer 1

Probably, it can't build mysql2 native extension.

If you're using Ubuntu 14.04 or newer, try sudo apt-get install ruby-mysql libmysqlclient-dev.

On older versions of Ubuntu install this: sudo apt-get install libmysql-ruby libmysqlclient-dev

On OS X: brew install mysql

There are also similar questions: 1, 2, 3.

Answer 2

我正在使用 LInux 16 Cinnamon 并收到该错误消息。我使用“Resure”的解决方案 sudo apt-get install libmysql-ruby libmysqlclient-dev

然后为项目运行捆绑安装。

有效！
