Rails / Snow Leopard Mysql 64 位问题

Question

大家好，我正在尝试在 Snow Leopard 上安装 64 位 MySQL 以用于 Rails 应用程序。

我已经从 dmg 安装了它，并且可以从命令行正常访问 mysql。根据各种博客文章以及 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

这会产生以下内容：

最后的那两个警告似乎是不祥的。然后我转到我的 Rails 应用程序并运行

rake db:migrate

And get:

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

这就是我所能得到的。我尝试通过 dmg 和 macports 安装 MySQL，在这两种情况下似乎都遇到了这个错误。

说到 Rails，我有点菜鸟。任何人都能提供的任何启发都将受到极大的赞赏。谢谢！

回应下面约翰（和 khelll）的回答：

当我执行约翰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。我认为这是因为文档。但是当我执行 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，我没有从源代码安装。再次查看 Hivelogic 说明后，我沿着这条路走了下去。

当我尝试运行：

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

我得到：

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

但是，在执行所有步骤之后，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 - 我相信发生了什么即使我在上面指定了 64 位 gem，它也会安装 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

并得到：

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

所以看来我继续安装 32 位版本

Answer 1

我按照这些关于 Hivelogic 的说明从源代码安装了它，效果很好。然后我使用以下命令安装了 MySQL RubyGem：

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