gem安装mysql失败 [英] gem install mysql fail

问题描述

我按照 http://geryit.com/blog/2011/01/installing-mysql-with-rails-on-mac-os-x-snow-leopard/ ，包括安装红宝石通过macport。

每当我执行 gem install mysql 时，我会收到以下错误消息

  bash-3.2＃gem install mysql 
构建原生扩展。这可能需要一段时间... 
错误：安装mysql时出错：
错误：无法构建gem本机扩展。

提供的配置选项：
 --with-opt-dir 
 --with-opt-include 
 --without-opt-include = $ {opt- dir} / include 
 --with-opt-lib 
 --without-opt-lib = $ {opt-dir} / lib 
 --with-make-prog 
 --without-make-prog 
 --srcdir =。 
 --curdir 
 --ruby = / opt / local / bin / ruby​​ 
 --with-mysql-config 
 --without-mysql-config 
 
 
 Gem文件将保留安装在/opt/local/lib/ruby/gems/1.8/gems/mysql-2.8.1中进行检查。 
将结果记录到/opt/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/ext/mysql_api/gem_make.out 
  

我该如何解决这个问题？我已经使用软件包文件（.pkg）安装了32位mysql，并且我对ruby非常新颖......

更新4/26/11 5:11 pm EST
安装了RVM并更新了ruby到1.9.2
我也查看了评论中发布的链接。我做了>找到mysql_config
，结果为

  / usr /local/mysql-5.1.56-osx10.6-x86/bin/mysql_config 
 /usr/local/mysql-5.1.56-osx10.6-x86/man/man1/mysql_config.1 
  

因此，我尝试了
gem install mysql - -with-mysql-config = /usr/local/mysql-5.1.56-osx10.6-x86/bin/mysql_config
，但它仍然无法正常工作...但我收到了新的错误信息..

真的很想感谢那些评论过的人......并且非常感谢能否给予更多帮助.. ...试图让darn mysql安装2天...

解决方案

通过卸载32位解决了这个问题MySQL就是在我的系统上，并安装了5.1.56 64位。

希望这有助于其他与我有同样问题的人。

I've followed the instructions on http://geryit.com/blog/2011/01/installing-mysql-with-rails-on-mac-os-x-snow-leopard/ , including the installation of ruby via macport.

Whenever I execute gem install mysql , I'll get the following error

bash-3.2# gem install mysql
Building native extensions.  This could take a while...
ERROR:  Error installing mysql:
    ERROR: Failed to build gem native extension.

        /opt/local/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.

Provided configuration options:
    --with-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/opt/local/bin/ruby
    --with-mysql-config
    --without-mysql-config


Gem files will remain installed in /opt/local/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.
Results logged to /opt/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/ext/mysql_api/gem_make.out

How can I resolve this issue ? I've installed the 32-bit mysql using the package file (.pkg) and also, I'm extremely new to ruby...

Update 4/26/11 5:11pm EST Installed RVM and updated ruby to 1.9.2 Also I have looked through the links posted on the comments. I did locate mysql_config and results were

/usr/local/mysql-5.1.56-osx10.6-x86/bin/mysql_config
/usr/local/mysql-5.1.56-osx10.6-x86/man/man1/mysql_config.1

Hence, I tried gem install mysql - -with-mysql-config=/usr/local/mysql-5.1.56-osx10.6-x86/bin/mysql_config but it still doesn't work... I did get new error information however..

Really wish to thank those who commented... and really appreciate if more help can be given..... been trying to get the darn mysql installed for 2 days...

解决方案

Solved the problem by uninstalling 32-bit MySQL thats on my system.. and installed 5.1.56 64-bit.

Hope this is helpful to others who's having the same problem as me..
