【问题描述】：

我按照 heroku 网站上的说明安装了 heroku。当我运行 heroku login （或任何其他 heroku 命令，我得到下面的输出）。目录/home/jsltaic/.rvm/rubies/ruby-1.9.3-p194/lib 不存在，我怀疑这是问题的一部分。

jsltaic@Ubuntu1204:~$ heroku login

【解决方案1】：

首先尝试卸载导致与 CLI 冲突的 heroku gem

gem uninstall heroku

如果 heroku CLI 工作正常，请尝试，如果它没有按照此页面上的说明再次安装它https://toolbelt.heroku.com/
