使用 leiningen 时出现 ExceptionInInitializerError [英] ExceptionInInitializerError when using leiningen

问题描述

我是使用 Clojure 和 Leiningen 的初学者，在尝试使用各种 lein 命令时遇到了问题.尽管 $ lein deps 工作正常，但当我尝试使用 $ lein plugin install <plugin>，甚至 $lein help 时，我得到下面粘贴的堆栈跟踪.我猜这是一个设置问题，但我无法在线查找信息或找到合适的位置开始查找.安装 lein 时，我按照 Leiningen GitHub 页面 上的说明进行操作.

I'm a beginner getting started with using Clojure and Leiningen, and I've run into a problem trying to use a variety of lein commands. Although $ lein deps works fine, when I tried to use $ lein plugin install <plugin>, or even $lein help, I get the stack trace pasted below. I would guess that this is a setup issue, but I'm having trouble finding information online or finding the right place to start looking. When installing lein I followed the instructions on the Leiningen GitHub page.

推荐答案

(For the karma ;o) 您是否尝试过删除 .lein 目录并从零重新运行?听起来您可能缓存了损坏的 zip 文件.

(For the karma ;o) Have you tried deleting the .lein directory and re-running from zero? Sounds like you may have a corrupt zip file cached.
