mysql - Ruby on Rails 服务器无法启动 : dyld: lazy symbol binding failed: Symbol not found: _mysql_get_client_info

Question

环境(Mac OS X 10.7.2 - Lion):

$ ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin10]
$ rails -v
Rails 3.1.3
$ mysql -v
Server version: 5.1.44 

我尝试运行以下命令，但即使在应用了来自整个网络的修复后，我每次都会遇到同样的错误:

$ rails server

dyld: lazy symbol binding failed: Symbol not found: _mysql_get_client_info
Referenced from: /Users/pressplay/.rvm/gems/ruby-1.9.3-p0/gems/mysql2-0.3.11/lib/mysql2/mysql2.bundle
Expected in: flat namespace

Trace/BPT trap: 5

修复失败的尝试包括:

sudo install_name_tool -change libmysqlclient.16.dylib /Applications/MAMP/Library/lib/mysql/libmysqlclient.16.dylib ~/.rvm/gems/ruby-1.9.3-p0/gems/mysql2-0.3.11/lib/mysql2/mysql2.bundle

sudo ln -s /Applications/MAMP/Library/lib/mysql/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

如果您正在使用 rvm/不使用 rvm(只需使用 sudo)，那么请使用以下命令来解决问题。

rvmsudo ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config --with-opt-lib=/usr/local/mysql/lib
