ruby-on-rails-3 - ruby -heroku : command not found

Question

这个问题之前已经发布过，但答案没有奏效。我应该 proberley 提到我对 ruby​​ 完全陌生。我在做教程时遇到了错误
这里是步骤:

[first_app (master)]$ gem install heroku

我明白了

Successfully installed heroku-2.24.0

但是当我尝试时

[first_app (master)]$ heroku keys:add

我明白了

-bash: heroku: command not found

然后我尝试了一堆卸载 gem 更新包重新安装它，但没有帮助

$ bundle exec heroku

/Users/vng/.rbenv/versions/1.9.3-p125/lib/ruby/gems/1.9.1/gems/bundler-1.1.3/lib/bundler/rubygems_integration.rb:147:在 `block in replace_gem':heroku 不是 bundle 的一部分。将其添加到 Gemfile。 ( gem ::加载错误) 来自/Users/vng/.rbenv/versions/1.9.3-p125/bin/heroku:18:in'`

echo $PATH

/Users/vng/.rbenv/shims:/Users/vng/.rbenv/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

当您安装包含二进制文件(可执行文件)的 gem 时，您必须运行

rbenv rehash

将可执行文件添加到您的路径。
