MySQL Gem 失败:雪豹上的 MysqlCompat::MysqlRes

Question

我正在尝试让 mysql gem 工作......但它只是不想这样做。每次我执行 rake db:migrate 时，我都会得到

uninitialized constant MysqlCompat::MysqlRes

我已经从这个磁盘镜像安装了 mysql:mysql-5.5.9-osx10.6-x86_64.dmg

我已经使用 inknown archflags 设置运行 gem 安装:

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

我使用的 ruby​​ 版本是 Snow Leopard 的默认版本:

[~/sites/testdb]$ file `which mysql`
/usr/local/mysql/bin/mysql: Mach-O 64-bit executable x86_64
[~/sites/testdb]$ file `which ruby`
/usr/bin/ruby: Mach-O universal binary with 3 architectures
/usr/bin/ruby (for architecture x86_64):    Mach-O 64-bit executable x86_64
/usr/bin/ruby (for architecture i386):  Mach-O executable i386
/usr/bin/ruby (for architecture ppc7400):   Mach-O executable ppc

我的database.yml非常简单:

development:
  adapter: mysql
  host: 127.0.0.1
  database: testdb
  username: root
  password: 

如有任何帮助，我们将不胜感激。

您可以轻松解决问题。

如果您不使用rvm:

sudo install_name_tool -change libmysqlclient.16.dylib /usr/local/mysql/lib/libmysqlclient.16.dylib /Library/Ruby/Gems/1.8/gems/mysql-2.8.1/lib/mysql_api.bundleruby

如果您使用rvm:

install_name_tool -change libmysqlclient.16.dylib usr/local/mysql/lib/libmysqlclient.16.dylib [YOUR_GEMSET_PATH]/gems/mysql-2.8.1/lib/mysql_api.bundle
