创建新应用程序时 RVM 和 Rails 出现问题

当尝试rails new myapp在以下路径下执行时：/home/novito/Projectes我收到以下错误：

Can't initialize a new Rails application within the directory of another, please change to a non-Rails directory first.
Type 'rails' for help.

我想象我可能在主文件夹中创建或复制了一个 Rails 应用程序，所以我去了那里，这是我执行时所列出的内容ls -la

因此，我尝试删除配置和供应商，因为它们是其他 rails 应用程序相关的文件夹...但是当我删除配置时，如果我尝试执行 rails new，我会收到此错误：

<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- /home/novito/config/boot (LoadError)
    from <internal:lib/rubygems/custom_require>:29:in `require'
    from script/rails:5:in `<main>'

我真的不知道这里发生了什么，如果有人能提供任何提示，我将不胜感激。

该问题可以转移到www.stackoverflow.com

您可能在 /home/novito/Projectes/ 文件夹中还有另一个 rails 应用程序。

检查这里的答案（我不知道是否相关）：https://stackoverflow.com/questions/3865515/strange-inability-to-require-config-boot-after-upgrading-to-ruby-1-9-2

我没有使用 ruby​​/rails，但是如果上述方法不起作用，我认为您需要重新安装使用 rvm 下载的 ruby​​ 版本：http://beginrescueend.com/

rvm implode
bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
rvm requirements # Find the requirements (follow the instructions)
rvm install 1.9.3 # Change 1.9.3 with your version

有关 rvm 的更多信息（请查看“基础知识”）：http://beginrescueend.com/rvm/

然后重试：

reset
mkdir -p /home/novito/Projectes/mynewrailapp
which ruby #check you are using the correct version of ruby
which rails #check you are using the correct version of rails
rails new myapp /home/novito/Projectes/mynewrailapp
