I'm using ruby 2.3, and in the gemfile, I've got the mysql2 gem listed. But when I try to run rake db:migrate, I get the following:
我正在使用ruby 2.3，并且在gemfile中，我已经列出了mysql2 gem。但是当我尝试运行rake db：migrate时，我得到以下内容：
/Users/me/.gem/ruby/2.3.0/gems/mysql2-0.4.2/lib/mysql2.rb:31:in `require': incompatible library version - /Users/me/.gem/ruby/2.3.0/gems/mysql2-0.4.2/lib/mysql2/mysql2.bundle (fatal)
I can't seem to get around this one. I've installed Mysql 5.7 with Homebrew, tried updating the bundle, uninstalling and reinstalling the mysql2 gem, all to no avail.
我似乎无法解决这个问题。我已经用Homebrew安装了Mysql 5.7，尝试更新捆绑包，卸载并重新安装mysql2 gem，但都无济于事。

I experienced the same issue. I had ruby 2.3.4 installed and using rails 4.6.2.
我遇到了同样的问题。我安装了ruby 2.3.4并使用了rails 4.6.2。
There were two issues causes and the support team of the hosting company I was using helped me resolve the issue.
有两个问题原因，我使用的托管公司的支持团队帮助我解决了这个问题。
The first was that the mysql2 lib that was installed was, by default, linked to ruby 1.8 instead of ruby 2
第一个是默认情况下安装的mysql2 lib链接到ruby 1.8而不是ruby 2
# lld ../2.2.0/mysql2-0.4.4/mysql2/mysql2.so
...
...
libruby.so.1.8 => /usr/lib64/libruby.so.1.8 (0x00007f2af1f8a000)
...
Second issue was to compile the lib with the installed mysql server config
第二个问题是使用已安装的mysql服务器配置编译lib
So mysql2 gem had to be uninstalled and re-installed with the right ruby lib and compiled with the right mysql config.
因此必须卸载mysql2 gem并使用正确的ruby lib重新安装并使用正确的mysql配置进行编译。
Below are the commands.
以下是命令。
gem uninstall mysql2
gem install mysql2 -- --with-mysql-config=/usr/bin/mysql_config --with-opt-lib=/where/my/ruby22/lib_was_located/
