Yes I know this has been asked before. I have already reviewed the following links and followed the steps included in them and the result is the same each time.

根据以下链接，在执行以下命令之前，我先运行"sudo gem卸载mysql"，然后运行"sudo gem clean mysql":

Prior to the following commands I run "sudo gem uninstall mysql" followed by "sudo gem clean mysql" based on the above links:

• sudo gem install mysql---with-mysql-config =/usr/local/mysql/bin/mysql_config

It is still failing. I am just flumoxed and would greatly appreciate any help.

非常感谢！

推荐答案

我自己没有经验，我正在使用Snow Leopard，RVM和Rails 2.3.5至3.0.3，但是找到了另一种可以处理卸载的视图并通过:

Not had the experience myself and I'm using Snow Leopard, RVM and rails 2.3.5 to 3.0.3, but found another view which deals with the uninstall and reinstall via :

export ARCHFLAGS="-arch i386 -arch x86_64" ;sudo gem install --no-rdoc --no-ri -v=2.7 mysql -- --with-mysql-dir=/usr/local/mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config
