mysql - 无法启动 WEBRick Web 服务器 - Ruby 抛出 MySQL 错误

Question

我是使用 64 位计算机的 Windows 8.1 用户。但是，我已经在 32 位版本中安装了与 Ruby 有关的所有内容，以防止互联网上出现那些著名的错误。这还不够……我在尝试启动 Rails 的提到 MySQL 的 WEBBrick 服务器时仍然收到一个奇怪的错误:

前几天我确实在让 MySQL 工作时遇到了一些麻烦，但我通过使用 MySQL C 连接器 6.0.2 做了一些我不理解的事情解决了它，然后早些时候我不能获取要安装的包，因为它要求安装 mysql2 0.3.15，但显然我有 mysql2 0.3.13。我不确定哪里错了。因此，我从 dev.mysql.com 获得的更新后的 C 连接器解决了捆绑问题，但现在 Web 服务器无法运行。

我不知道设置 Ruby on Rails 会如此痛苦，但我仍然对此充满动力，我需要帮助才能继续。

谢谢。

尝试看看这个答案是否对您有帮助mysql2 gem compiled for wrong mysql client library :

There's a helpful message that is shown when you gem install mysql2. Unfortunately, if you install the gem with Bundler, Bundler eats the message
