使用MAMP 2.2在Mac上"gem install mysql2"

当rails server我尝试在我当前的目录(这是一个新的rails项目)中运行时,它说我需要安装mysql2gem.起初,我不知道这意味着什么......然后,我做了一些戳,最后决定安装宝石.但是,我得到了这个超级麻烦的错误(因为我只花了2个小时试图调查,并解决了另一个错误).我处于放弃的边缘,但我真的想试试铁轨.请帮忙!

目前,如果我跑sudo gem install mysql2,或者甚至有些人告诉我在网上做gem install mysql -- \ --with-mysql-config=/Applications/MAMP/Library/bin/mysql_config(我有MAMP),它会给我以下错误:

您是否考虑过使用自制软件安装MySQL(http://brew.sh/)？MAMP代表Mac-Apache-MySQL-PHP(其中最重要的部分是最重要的).我建议只在你的盒子上直接安装MySQL(自制软件负责所有繁重的工作),然后我怀疑你在安装这个宝石时遇到任何困难.

安装自制软件 -

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

brew doctor按照任何说明运行,然后安装MySQL运行brew install mysql并按照它为设置用户提供的任何说明等...

=============更新==============

那么,你想要做的就是使用brew这种方式来安装MySQL,然后以正常的方式安装gem - sudo gem install mysql2假设这有效,那么你将能够通过MAMP切换回旧的MySQL安装 -

sudo nano /etc/paths

然后将此行添加到文档的顶部 -

/Applications/MAMP/Library/bin

重新启动你的终端,然后运行mysql以仔细检查你是否正在使用MySQL的MAMP安装,你会很高兴.
