我曾在Ubuntu上使用Ruby版本1.9.3工作,但一次更新可能破坏了我的bash配置文件。我需要帮助把它恢复过来,而不是继续使用版本1.8.7。目前
rails s
打开服务器时使用的是Ruby 1.8.7,因为我在应用程序中使用了新的语法,所以会出现错误。
.bash_profile:cat ~/.bash_profile

You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
