自上次捆绑更新以来,rails控制台中的每个操作(rails服务器,rails控制台,db:migrate等)都会发出警告:

[fog][WARNING] Unable to load the 'unf' gem. Your AWS strings may not be properly encoded.

我确定我没有更改我的application.rb文件中的AWS字符串中的任何内容:

    # Amazon S3 credentials
ENV["AWS_ACCESS_KEY_ID"] = "AWS_ACCESS_KEY_ID"
ENV["AWS_SECRET_ACCESS_KEY"] = "AWS_SECRET_ACCESS_KEY"
ENV["AWS_S3_BUCKET"] = "my-bucket"

我的gemfile中没有这个"unf"gem.我应该加吗？

我刚刚在我的Macbook上安装了一个新的Ruby on Rails dev堆栈,它运行Mac OS X 10.9 Mavericks.

这是我的堆栈:

• Xcode命令行工具
• 家酿
• Rbenv
• 捆绑
• Ruby 2.1.0
• Rails 4.1.1

我跑去rails new test_app生成第一个测试应用程序.此命令已成功完成,但由于它,我在CLI中尝试的每个Rails命令都会返回此类错误消息:

$ test_app > bin/rails server

尝试启动控制台时出现相同的错误:

$ test_app > bin/rails c

在我的计算机上的每个Rails项目上,因为我重新安装它,我无法运行任何迁移:当我进入rake db:migrate终端时没有任何反应

$ my_project ? rails g migration fake_migration

    invoke  active_record
    create  db/migrate/20140806092408_fake_migration.rb

$ my_project ? rake db:migrate:status
