跟踪/BPT 陷阱

Answer 1

再次从安装程序更新 MySQL（例如mysql-5.5.10-osx10.6-x86_64 ）。

然后 MySQL2 gem： $ sudo gem install mysql2 -- --with-mysql-config=/usr/local/mysql-5.5.10-osx10.6-x86_64/bin/mysql_config

它对我有用。

Answer 2

可能这篇文章与您的问题相似： Library not loaded: libmysqlclient.16.dylib error when trying to run 'rails server' on OS X 10.6 with mysql2 gem

Answer 3

尝试这个：

export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/usr/local/mysql/lib/"

把它放在你的.profile（或.bashrc）中并输入这个命令

my_term> source.profile

将“/usr/local/mysql/lib/”替换为 MySQL 客户端的安装位置

Answer 4

我也遇到了这个问题，我在这里或其他问题中找到的任何建议都没有让我到任何地方，但是以 root 身份运行（使用sudo rails s ）。 我想当以 root 身份运行时，它使用 mysql 库的正确路径，但是按照此处链接之一中的说明使用install_name_tool更改它也不起作用。 只要我没有发现问题，我就需要使用 sudo 启动我的 rails 应用程序。

Answer 5

对于永久修复，请尝试通过命令创建软链接 -

sudo ln -s /usr/local/mysql/lib/libmysqlclient.16.dylib /usr/lib/libmysqlclient.16.dylib
