奇怪的是，我無法在某些情況下執行典型的Rails命令，例如rails s和rails c。爲什麼Rails命令強制爲`new`命令提供幫助信息？
我發現這發生在某個特徵分支上，也偶爾也發生在過去，但目前在我的develop分支上工作。
我將任何可加載並且有效的.rb文件都對齊，但這並沒有幫助，其他更改是.sh文件和自述文件更新。
文字，我不希望看到：

Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.
Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.
文字我想看看：
