I have no idea why. I also reinstalled my verison of MySQL with the MySQL 5.4.3 beta, 64-bit as others suggested but no dice. Does anyone have any idea what is wrong?
我不知道为什么。我还按照其他人的建议，使用 MySQL 5.4.3 测试版（64 位）重新安装了我的 MySQL 版本，但没有骰子。有谁知道出了什么问题？

You are missing libmysqlclient-dev package. On Deb systems you could install this using
您缺少 libmysqlclient-dev 包。在 Deb 系统上，您可以使用
sudo apt-get install libmysqlclient-dev
Not sure about mac (maybe "sudo port install libmysqlclient-dev" ?)
不确定 mac（也许是“sudo port install libmysqlclient-dev”？）

I had the same issue, and the above solution did not work until I fixed my $PATH: PATH="/usr/local/bin:/usr/local/sbin:$PATH" # if not already present PATH="$PATH:/usr/local/mysql/bin" export PATH=$PATH
我遇到了同样的问题，直到我修复了 $PATH: PATH="/usr/local/bin:/usr/local/sbin:$PATH" # if not already present PATH="$PATH :/usr/local/mysql/bin" 导出 PATH=$PATH

sudo env ARCHFLAGS="-arch x86_64" gem install do_mysql -- --with-mysql-dir=/usr/local/mysql/
回答by fannar
You require both Mysql to be installed and the path to the Mysql binary added to your profile.
您需要安装 Mysql 并将 Mysql 二进制文件的路径添加到您的配置文件中。
1) Download and install the MySQL binary (make sure you pick the correct CPU architecture).
1) 下载并安装 MySQL 二进制文件（确保选择正确的 CPU 架构）。
2) Edit the file ~/.profileand add :/usr/local/mysql/binto your path.
2) 编辑文件~/.profile并添加:/usr/local/mysql/bin到您的路径中。
3) In a new terminal window do sudo gem install do_mysql
3）在一个新的终端窗口做 sudo gem install do_mysql
Hope that helps!
希望有帮助！

Try this
试试这个
sudo env ARCHFLAGS="-arch x86_64"
gem install do_mysql --with-mysql-dir=/usr/local/mysql/ --ruby=/opt/local/bin/ruby1.9
sudo env ARCHFLAGS="-arch x86_64"
gem install do_mysql --with-mysql-dir=/usr/local/mysql/ --ruby=/opt/local/bin/ruby1.9
You have to specify the location of your mysql installation, as well as the location of the ruby installation, since you are using ruby1.9, I am assuming you may have 1.8 running as well on your machine.
您必须指定 mysql 安装的位置，以及 ruby 安装的位置，因为您使用的是 ruby1.9，我假设您的机器上也可能运行 1.8。
