我是 Rails 的初学者，我一直关注 ruby​​.railstutorials.org，直到我坚持本节http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec:1.4.1

在我安装 heroku gem 之后gem install heruku

我输入heroku keys:add然后我得到了这些错误。

尝试使用正确的拼写再次安装 gem：

gem install heroku

检查您正在使用的 ruby​​ 版本

rvm list
ruby -v
gem list

你需要切换到正确的红宝石

rvm use <ruby version>

然后再次安装heroku。

获取Home Brew，然后运行命令“brew doctor”。如果它告诉您有错误，请修复这些错误。

我猜您使用的是 Mac，并且您可能正在运行 MacPorts。这样做存在问题，因为 MacPorts 使用 rvm 尝试访问的旧库。您需要从 brew doctor 计划的路径中删除 opt 和一堆东西。
