我有问题当我尝试使用以下命令创建新的Rails项目/应用程序时：rails new app -d mysql或rails new app，我收到以下错误消息。
我的计算机运行的是Windows 10（64位），并且使用的是Rails 4.2.4。如果您需要更多信息，请随时询问。 （我删除了我的名字，所以这就是为什么您只看到Documents \ Sider的原因）
Documents\Sider>rails new cmsw -d mysql

最佳答案
如果您的原因像我的那样，这确实是一个令人讨厌的解决方案：
我的名字包括扩展的ASCII字符“ø”。当计算机在PC上设置我的帐户时，就使用了那个。例如。 c：\ users \Bjørn。
修复：将文件夹和您的家庭帐户重命名为Bjorn。
在系统上创建另一个管理员帐户，该帐户可用于将帐户重命名为c：\ users \ Bjorn \
这是重命名帐户的方法：https://superuser.com/questions/495290/how-to-rename-user-folder-in-windows-8
首先，我永远不会在用户名中使用扩展字符，但是几年前当我设置Win8并可能使用Microsoft帐户时，我就选择了用户名。
