我刚刚安装了Leiningen 2.4.3，它使用我的Ubuntu 14.04系统的安装脚本。当我尝试使用雷音进入REPL，我得到一个相当恶劣的转储到控制台：Leiningen REPL问题

我需要一些帮助解释这意味着什么，以及如何解决它。正在运行JDK 1.8.0_20
你有没有在.lein目录中的任何插件？ – 2014-08-30 00:05:54
我注意到您的提示，这不是在项目目录中，而是在您的主目录中。这是lein 2.4.3的一个已知问题，并且在项目目录外部进行了重新渲染，解决方案是降级直到有固定版本可用，请参阅我的上述评论。 – noisesmith 2014-08-30 00:19:41
