无法启动rails server mysql2 gem？ [英] Can't start rails server mysql2 gem?

问题描述

Ruby和Rails noob，做了一个项目，并得到了这么多。但是现在我在试图运行rails server的时候遇到了这些错误。我使用Windows vista和ruby 2.0.0。

到目前为止，我对ruby和gems知之甚少，但mysql2 gem似乎是一个问题，至少我已经安装并安装了这个问题，但没有任何帮助。我不断收到一条消息，告知我已经按照我所遵循的顺序安装了二进制版本。这是好事还是坏事？

任何人都请帮助我，如果您需要更多信息，请告诉我。

解决方案

基本上，您需要指出该宝石使用您的mysql实例安装在你的机器上。

I know very little about ruby and gems so far but the mysql2 gem seems to be a problem wich I have installed and installed to no help. I do constantly get a message that I have installed the binary version with orders that I've followed. Is this a good or bad thing?

Anyone please help me out, if you need more info just let me know.

解决方案

I think the answer here is what you are looking for:

Basically, you need to point the gem to use your mysql instance installed on your machine.
