我刚刚安装了 Uglify.js 并尝试使用它来重建 CoffeeScript，但不断收到此错误。当我在 CoffeeScript 目录中键入“cake build:browser”时会发生这种情况。（我想尝试修改 CoffeeScript 语言。）

我的 Uglify.js 是从 GitHub 克隆的，符号链接是在 .node_libraries 中创建的。Uglify 安装正确，确认它在 Node 中和通过命令行正常运行。所以也许这是一个 CoffeeScript 问题。

帮助？

好的，我能够复制这个。但是你为什么要克隆 UglifyJS 存储库？如果您只是npm install uglify-js安装到本地node-modules目录（使用 npm 1.x），一切运行正常。
