我无法安装捆绑的mysql2，我已经尝试了在这里以及在www上其他地方找到的所有内容。
xcode是最新的。 安装了MySQL 8.0.15 Mac OS X 10.12.6 Ruby 2.3.0 滑轨4 宝石1.9.3 家酿 功放
这是怎么回事： '''''''''
sudo bundle install
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all non-root users on this machine.

An error occurred while installing mysql2 (0.5.2), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.5.2' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
mysql2
然后我看mkmf，这根本没有给我任何线索。至少对我来说。 我为RoR弄得一团糟...
这是mkmf.log所说的。
