我是 RoR 的新手，我似乎无法启动 WEBrick 并倾听。这是控制台输出。我使用 Mountain Lion、Rails 3.2.8 和 Ruby 1.9.3。请帮忙

答案在这里：

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

OSX上的rails + MySQL：未加载库：libmysqlclient.18.dylib

--- 已编辑

你的 $DYLD_LIBRARY_PATH 不包含 /usr/local/mysql/lib 目录，所以有2个解决方案

  • 符号链接
  • 将 /usr/local/mysql/lib 添加到 .bashrc 或某处的 $DYLD_LIBRARY_PATH

不知道这个答案是否有帮助......但我本周遇到了同样的问题。

当我在谷歌上搜索答案时，我发现有用的只是将 gem 'thin' 放入 Gemfile。

（当然，这取决于已经安装了薄宝石）

然后运行 ​​bundle install 之后。（这会安装薄宝石）。

当您运行 rails server 时，它会自动与 Thin 一起使用。

希望这可以帮助！

看起来你的 mysql2 gem 没有正确安装。看看这个问题的答案。它应该可以帮助您进行设置。您需要先安装 mysql（我喜欢使用自制软件来执行此操作）。然后使用正确的路径安装 gem。

Ruby gem mysql2 安装失败
