Ruby on rails 设置RubyonRails的问题

我刚开始学习RubyonRails的“LyndaRubyonRails 3基本培训”

我完成了安装，并通过编写“rails新应用程序”创建了rails应用程序。 之后，当我写“rails服务器”时，我看到了：

你能帮我找到解决办法吗

节日快乐

Oded看起来你少了一些宝石！尝试运行

捆绑安装

。。。那么一切都应该起作用

编辑：确保您的

Gemfile

包含该行

gem 'mysql'

---

在运行

捆绑安装之前

。Bundler将为您设置mysql、依赖项和所有内容。

您必须访问此网站并按照说明操作

或者简而言之，从mysql或镜像站点下载文章中提到的连接器

运行以下命令：

gem install mysql --platform=ruby -- --with-mysql-dir=C:/mysql-connector-c-noinstall-6.0.2-win32

确保mysql连接器文件夹的路径正确且没有空格

完成后，请确保从解压和下载的连接器库中复制

libmysql.dll

文件，并将其放入Ruby\bin文件中

---

之后，删除连接器库并通过键入'rails server'启动它，确保您的gem文件具有

gem'mysql'

或

gem'mysql2'

行，我不确定是哪一行，所以请同时尝试这两个行。这太糟糕了，他们真的需要为windows解决这个问题。

对不起，添加了一个关于Gemfile要求的说明。另一个答案是正确的，根据本指南，您需要确保安装了mysql：它不会为他安装mysql，一些用户报告说，在没有本地安装mysql gem的情况下使用mysql gem会出现webrick问题。我的应用程序是这样安装的：“rails new app-d mysql”
