ruby-on-rails - 箱/rails :6: warning: already initialized constant APP_PATH

Question

我正在尝试执行我的 RoR 应用程序，但是当我执行命令时:rails s 显示以下错误:

/Users/Jarvis/Documents/Projects/Vincubo/vincubo/bin/rails:6: warning: previous definition of APP_PATH was here
Usage: rails COMMAND [ARGS]

The most common rails commands are:
 generate    Generate new code (short-cut alias: "g")
 console     Start the Rails console (short-cut alias: "c")
 server      Start the Rails server (short-cut alias: "s")
 dbconsole   Start a console for the database specified in config/database.yml
             (short-cut alias: "db")
 new         Create a new Rails application. "rails new my_app" creates a
             new application called MyApp in "./my_app"

In addition to those, there are:
 application  Generate the Rails application code
 destroy      Undo code generated with "generate" (short-cut alias: "d")
 plugin new   Generates skeleton for developing a Rails plugin
 runner       Run a piece of code in the application environment (short-cut alias: "r")

但是，当我执行命令时:

$ rake rails:update:bin

你的配置文件在

config/initializers 

我在删除 dragonfly_s3、dragonfly 和 s3_direct_upload 时出现此错误

在执行 bundle install 和 rails s 之后

同样的错误

删除了初始化文件，它工作了
