捆绑安装时MySql错误

问题描述

当我进行捆绑安装时，出现以下错误:

When I do Bundle Install, I get following error:

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

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Gem files will remain installed in /Users/manish/.rvm/gems/ruby-1.9.2-p290/gems/mysql2- 0.3.10 for inspection.
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:

In the Gemfile MySql is something like this:

gem "mysql2", ">=0.3.0"

当我还尝试使用brew和sudo安装MySql时，会出现以下错误:

And when I also try to install MySql using brew followed with sudo it gives following error:

 sudo: unable to execute /usr/local/bin/brew: Permission denied

我该如何解决?

推荐答案

我找到了解决方案，这里是:

I found my solution and here it is:

第1步:清理以前安装的rvm和Xcode

Step 1: Clean Up your previously installed rvm and Xcode

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

第2步:从App Store安装Xcode，否则安装程序可能会保存在启动板中.

Step 2: Install Xcode from App Store or the installer might be saved in your Launchpad.

第3步:安装HomeBrew:

Step 3: Install 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

Step 5: Install 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

Step 6: Install 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;
