Question

嘿所有，我正在尝试在Snow Leopard上安装64位MySQL用于rails应用程序。

我已经从dmg安装了它，我可以从命令行获得mysql。基于各种博客文章以及Stack上的其他主题，我关闭了mysql，卸载了mysql gem，然后尝试使用以下内容更新gem：

sudo env ARCHFLAGS='-arch x86_64' gem install --verbose --no-rdoc --no-ri mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

产生以下内容：

/usr/bin/install -c -m 0755 mysql_api.bundle /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib

最后那两个警告似乎不祥。然后我去我的rails应用程序并运行

rake db:migrate

得到：

dyld: NSLinkModule() error
dyld: Symbol not found: _mysql_affected_rows
  Referenced from: /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
  Expected in: flat namespace
 in /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
Trace/BPT trap

这就是我能够得到的。我尝试通过dmg和macports安装MySQL，在这两种情况下我似乎遇到了这个错误。

当涉及到铁轨时，我有点像菜鸟;任何人都可以流下的任何光都会受到高度赞赏。谢谢！

回应下面John的（和khelll的）答案：

当我执行John指定的第一个命令时，我得到：

No definition for next_result

No definition for field_name

No definition for field_table

大约有40行。我以为这是因为文档。但是，当我做rake db：migrate时，我得到：

dyld: NSLinkModule() error
dyld: Symbol not found: _mysql_affected_rows
  Referenced from: /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
  Expected in: flat namespace
 in /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
Trace/BPT trap

使用ARCHFLAGS命令会产生我之前指定的错误。

我应该补充一点，我从源代码不安装。在再次查看Hivelogic指令之后，我走了这条路。

当我试图跑步时：

./configure --prefix=/usr/local/mysql --with-extra-charsets=complex \
--enable-thread-safe-client --enable-local-infile --enable-shared \
--with-plugins=innobase

我得到了：

config.status: creating zlib/Makefile
dyld: Library not loaded: /opt/local/lib/libintl.8.dylib
  Referenced from: /opt/local/bin/gawk
  Reason: no suitable image found.  Did find:
    /opt/local/lib/libintl.8.dylib: mach-o, but wrong architecture
./config.status: line 1782: 69228 Done(141)               eval sed ç"ç$ac_sed_extraç" "$ac_file_inputs"
     69229 Trace/BPT trap

所以我做了：

sudo port deactivate gettext
sudo port activate gettext @0.17_3

然而，在完成所有步骤之后，重新安装gem，在rake db：migrate上我仍然得到：

dyld: NSLinkModule() error
dyld: Symbol not found: _mysql_affected_rows
  Referenced from: /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
  Expected in: flat namespace
 in /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
Trace/BPT trap

----第三次编辑----

好的 - 我相信这里发生的事情是，尽管我正在指定上面的64位gem，但它正在安装32位版本。我这样做：

file /usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle

得到：

/usr/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle: Mach-O bundle i386

所以看起来我一直在安装32位版本

Answer 1

我是在these instructions on Hivelogic之后从源代码安装的，但效果很好。然后我使用：

安装了MySQL RubyGem

sudo gem install mysql -- --with-mysql-dir=/usr/local/mysql
