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

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

尝试‘创业板安装readline’，但仍然存在问题。

Answer 1

我想您也需要将此宝石添加到Gemfile中。然后运行bundle install

如果您没有Gemfile，那么您需要像相关指南中描述的那样运行Gemfile

Answer 2

我认为你需要先把丢失的宝石安装到你的系统中。

为此，您必须运行命令行中的代码“gem install GEME”。

在此之后，仍然会出现错误，那么您必须在conf/environment.rb . in中添加创业板，因为应用程序有rails 2.3.18。
