[英]OS X Lion with xampp + rails + mysql2 gem
我一直试图找出如何通过XAMPP安装的MySQL使OS X Lion与rails中的mysql2 gem一起工作。
这是我尝试过的:
这是我正在尝试尝试安装的命令:
gem install mysql2 -- --with-mysql-dir=/var/mysql --with-mysql-include=
/var/mysql/include --with-mysql-lib=/var/mysql/lib --with-mysql-config=
/Applications/XAMPP/xamppfiles/bin/mysql_config
我很茫然如何使它工作。 我唯一能想到的是,我以某种方式未正确指向目录。 我试过从with-mysql-include,with-mysql-dir和with-mysql-lib配置选项中删除/ include /,/ mysql /和/ lib /。 没有运气。 我尝试将其指向XAMPP安装。 仍然没有运气。
返回的错误是:
ERROR: Error installing mysql2:
ERROR: Failed to build gem native extension.

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.
Provided configuration options:

--with-opt-include

Gem files will remain installed in /Users/user/.rvm/gems/ruby-1.9.3-p194/gems/mysql2-0.3.11 for inspection.
Results logged to /Users/user/.rvm/gems/ruby-1.9.3-p194/gems/mysql2-0.3.11/ext/mysql2/gem_make.out
最好不要理会XAMPP提供的东西,而只安装MySQL的新副本,并简化安装mysql2的Gem命令:
brew install mysql
gem install mysql2
由于所有这些,在通过Homebrew安装MySQL之后,您在安装gem时遇到错误:
--with-mysql-dir=/var/mysql --with-mysql-include= \
/var/mysql/include --with-mysql-lib=/var/mysql/lib --with-mysql-config= \
/Applications/XAMPP/xamppfiles/bin/mysql_config
因此,删除它可以解决问题。
