执行Bundle安装时MySql出错
当我执行Bundle Install时，出现以下错误：
Installing mysql2 (0.3.10) with native extensions Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /Users/manish/.rvm/rubies/ruby-1.9.2-p290/bin/ruby extconf.rb checking for rb_thread_blocking_region()... yes checking for rb_wait_for_single_fd()... no *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

Results logged to /Users/manish/.rvm/gems/ruby-1.9.2-p290/gems/mysql2- 0.3.10/ext/mysql2/gem_make.out An error occured while installing mysql2 (0.3.10), and Bundler cannot continue. Make sure that `gem install mysql2 -v '0.3.10'` succeeds before bundling. 在Gemfile中，MySql是这样的：
gem "mysql2", ">=0.3.0"
当我还尝试使用brew后跟sudo安装MySql时，会出现以下错误：
sudo: unable to execute /usr/local/bin/brew: Permission denied
我该如何解决这个问题？
我找到了我的解决方案，这里是：
第1步：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，或者安装程序可能会保存在Launchpad中。
第3步：安装HomeBrew：
=> mkdir -p /usr/local/Cellar => /usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"
第4步：安装RVM
=> bash < <(curl -s https://rvm.beginrescueend.com/install/rvm) => echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile
第5步：安装Ruby 1.9.2
=> rvm install 1.9.2 => rvm use ruby-1.9.2 --default => gem install rails thin bundler => rvm install 1.9.2-head => brew install git ack wget curl redis memcached libmemcached colordiff imagemagick
第6步：安装MySql
=> brew install mysql => mysql_install_db --verbose --user=`whoami` --basedir="$(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;
您可以下载库并将其位置手动传递给gem构建过程作为标志，但这有点痛苦。
MySQL正在/ usr / local / bin中进行搜索，这对于自制软件安装是有意义的，但如果sudo brew不起作用，则存在权限问题，并且您可能遇到更多麻烦。
我老老实实地修理啤酒，这将继续让你感到沮丧。 正常舞蹈修复 – 使用Disk Utitlity修复权限，运行brew医生检查问题，内爆并重新安装，如果事情变坏。
祝好运
