执行捆绑包安装时MySql出错

当我进行捆绑安装时，出现以下错误：

当我尝试使用brew和sudo安装MySql时，会出现以下错误：

如何解决这个问题？

您可以下载库并将它们的位置作为标志手动传递到gem构建过程，但这有点麻烦

MySQL正在/usr/local/bin中搜索，这对于安装自制软件来说是有意义的，但如果sudo brew无法工作，则会出现权限问题，您可能会遇到更多的问题

我会修复将继续困扰您的b/c。修复的正常舞蹈——使用磁盘实用性修复权限，运行brew doctor检查问题，如果出现问题，则内爆并重新安装

祝你好运

我找到了解决方案，它就在这里：

步骤1：清理以前安装的rvm和Xcode

    => rm -rf ~/.rvm    
    => sudo rm -rf /Developer

步骤2：从App Store安装Xcode，否则安装程序可能会保存在您的启动板中

步骤3：安装自制软件：

    => mkdir -p /usr/local/Cellar
    => /usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"

步骤4：安装RVM

    => bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
    => echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" #  Load RVM function' >> ~/.bash_profile

步骤6：安装MySql

    => brew install mysql
    => mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
    => mkdir -p ~/Library/LaunchAgents
    => cp /usr/local/Cellar/mysql/5.5.15/com.mysql.mysqld.plist ~/Library/LaunchAgents/
    => launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
    => mysql -u root
    => UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';
    => FLUSH PRIVILEGES;

我做了标记，但正如你们所知，为自己的问题标记答案需要两天时间。无论如何，谢谢你的提醒：）
