You're running a version of ruby with no Readline support

Please `gem install rb-readline` or recompile ruby --with-readline.

尝试'gem install rb-readline'，但仍有问题。

Answer 1

我猜你也需要将这个gem添加到Gemfile中。然后运行bundle install

如果您没有Gemfile，那么您需要像relevant guide中描述的那样运行rake gems:install

Answer 2

我认为您需要先将缺少的宝石安装到您的系统中。

为此你必须在命令行'gem install GEME NAME'

中运行代码

之后仍然出现错误，那么你必须在conf / environment.rb中添加那个gem，因为应用程序有rails 2.3.18。
