[英]Rails console doesn't start?
我將首先在我的機器上寫下 ruby 和 rails 的路徑和版本,然后是我遇到的錯誤。
which rails
/Users/alex/.rvm/gems/ruby-3.0.3/bin/rails
rails -v
Rails 7.0.1
which ruby
/Users/alex/.rvm/rubies/ruby-3.0.3/bin/ruby
ruby -v
ruby 3.0.3p157 (2021-11-24 revision 3fb7d2cadc) [x86_64-darwin21]
當我嘗試運行rails console
時,它不會運行,但會顯示以下選項:

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,
or in $XDG_CONFIG_HOME/rails/railsrc if XDG_CONFIG_HOME is set.
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.
您是否創建了 Rails 應用程序? 看起來您正在一個尚未創建 Rails 應用程序的目錄中運行rails console
。
您應該使用rails new [app_name]
創建一個新應用程序,然后運行rails console
。 或者,確保您位於現有 Rails 應用程序的根目錄中。
