Answer 1

在save-history.rb:76处检查源代码，看来您的历史记录文件有问题。我会尝试删除IRB历史记录文件。根据{{3}}，它可以在多个地方

如果您的HOME环境已设置：

rm ~/.irb_history

如果不是，则从工作目录：

rm .irb_history irb.history _irb_history '$irb_history`

Answer 2

我已经修改了save-history.rb文件。

f.each {|l| HISTORY << l.gsub("\u0000", '').chomp}.

现在可以正常工作了。

Rails控制台不起作用。得到这个错误
