The other day I updated to Mac OSX Lion. 前几天我更新到Mac OSX Lion。 It broke my rails install as I had to re complie mysql.
它打破了我的rails安装,因为我不得不重新编译mysql。 While I have got that working reinstalling the mysql2 gem has become problematic.

So far I have recompiled and installed MySQL and updated RVM to head. 到目前为止,我已经重新编译并安装了MySQL并更新了RVM。 I have also installed Xcode however I have had no luck.
我也安装了Xcode,但我没有运气。
Suggestions? 建议?
$ locate mysql_config
so you can find path to it $ locate mysql_config
,你可以找到它的路径 $ sudo gem install mysql2 -- –with-mysql-config=/path/to/mysql_config
$ sudo gem install mysql2 -- –with-mysql-config=/path/to/mysql_config
Don't know if this will help, but lemme try. 不知道这是否有帮助,但是试试看。
To make mysql2 gem working under my OSX Lion, running Ruby 1.8.7: 为了让mysql2 gem在我的OSX Lion下工作,运行Ruby 1.8.7:
Install mysql - Download mysql-5.5.14-osx10.6-x86_64 安装mysql - 下载mysql-5.5.14-osx10.6-x86_64
Create an alias inside .bash_profile to mysql e MySQLCOM 在.bash_profile中创建一个别名到mysql和MySQLCOM
alias mysql="/usr/local/mysql/bin/mysql"
alias mysqld="sudo /Library/StartupItems/MySQLCOM/MySQLCOM"
Install gem 'mysql2', '0.3.6'
安装
gem 'mysql2', '0.3.6'
Create this symbolic link: 创建此符号链接:
sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
I got this installed in the system Ruby (1.8.7 on Lion) as follows: 我在系统Ruby(Lion上的1.8.7)中安装了这个,如下所示:
Add /usr/local/mysql/lib to your DYLD_LIBRARY_PATH (I prefer this to the symbolic link solution but they should be equivalent). 将/ usr / local / mysql / lib添加到您的DYLD_LIBRARY_PATH(我更喜欢这个符号链接解决方案,但它们应该是等效的)。 I did this in my .bash_profile via:
我在.bash_profile中通过以下方式做到了这一点:
export DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$DYLD_LIBRARY_PATH"
Execute: 执行:
env ARCHFLAGS="-arch x86_64" sudo gem install mysql2 -- --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib --with-mysql-include=/usr/local/mysql/include --with-mysql-config=/usr/local/mysql/bin/mysql_config
我通过重新安装ruby解决了这个问题 - 这似乎是必需的,因为编译器在Lion中更新。
