您好我已经使用rvm安装了ruby和rails但是每当创建一个新项目时它都会显示一些错误：

我建议使用http://rbenv.org/代替rvm，使用
轻量级和简化在尝试启动新的rails项目之前，请确保正确安装Rails和ruby以及在轨道上基本需要ruby。
我不知道你在哪个平台上工作，但是有一个合适的rails环境设置是好的。
http://www.createdbypete.com/articles/ruby-on-rails-development-setup-for-mac-osx/ 在rails设置上查看本教程中适当的ruby。
之后，一个简单的＆＃34; rails new mynewproject＆＃34;应该这样做。

我有同样的错误。我检查了它的用户控件
ls -ld /NepalRailsProject
drwxr-xr-x 2 root wheel 68 Oct 27 11:02 /NepalRailsProject
其他用户无权访问写入文件。因此，将其更改为可访问文件系统
chmod o+w /NepalRailsProject
并检查
ls -ld /NepalRailsProject
drwxr-xrwx 2 root wheel 68 Oct 27 11:04 /NepalRailsProject
现在，尝试创建新项目，它将创建新项目。
