當嘗試這樣做時rails new myapp，在這條路徑下：/home/novito/Projectes我收到以下錯誤：
Can't initialize a new Rails application within the directory of another, please change to a non-Rails directory first.
Type 'rails' for help.
我想也許我在我的主資料夾中創建或複製了一個 Rails 應用程序，所以我去了那裡，這是我在做時的列表ls -la

因此，我嘗試刪除配置和供應商，因為它們是其他與 Rails 應用程式相關的資料夾...但是當我刪除配置時，如果我嘗試執行 Rails new 操作，則會收到此錯誤：
<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>'
我真的不知道這裡發生了什麼，如果有人可以提供任何提示，我將非常感激。

這個問題可以轉至www.stackoverflow.com
您可能在 /home/novito/Projectes/ 資料夾中有另一個 Rails 應用程式。
檢查這裡的答案（我不知道是否相關）：https://stackoverflow.com/questions/3865515/strange-inability-to-require-config-boot-after-upgrading-to-ruby-1-9-2
我不使用 ruby/rails，但是如果上面的方法不起作用，我認為你需要重新安裝用 rvm 下載的 ruby 版本：http://beginrescuend.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
有關 rvm 的更多資訊（請參閱「基礎知識」）：http://beginrescueend.com/rvm/
然後再試一次：
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
