Question

虽然在第2.2节中做了https://www.railstutorial.org/book/toy_app教程，我必须写一下$ rails generate scaffold User name:string email:string，但我遇到了一些错误：

有什么建议吗？这一直困扰着我

Answer 1

问题是Rails 4.2.0beta及更高版本依赖于pty gem并且无法找到它。

`require': cannot load such file -- pty (LoadError)

这是因为Windows上尚未提供此gem。对于临时修复，您可以从web-console删除Gemfile gem并在删除该gem后运行bundle install。
