用grunt得到一个奇怪的错误：Object Gruntfile.js没有方法'flatten'
我得到这个奇怪的错误试图运行grunt： TypeError: Object Gruntfile.js has no method 'flatten'
我是node.js，npm，grunt等的新手。我以为我做了一个像样的安装节点，npm，咕噜，但可能是我错过了一些东西。 有没有办法validation安装？
$ cat xx $ grunt /home/cl/node_modules/grunt/node_modules/findup-sync/lib/findup-sync.js:33 }).flatten().uniq().value(); ^ TypeError: Object Gruntfile.js has no method 'flatten' at Object.module.exports [as findup] (/home/cl/node_modules/grunt/node_modules/findup-sync/lib/findup-sync.js:33:8) at Task.task.init (/home/cl/node_modules/grunt/lib/grunt/task.js:414:16) at Object.grunt.tasks (/home/cl/node_modules/grunt/lib/grunt.js:113:8) at Object.module.exports [as cli] (/home/cl/node_modules/grunt/lib/grunt/cli.js:38:9) at Object.<anonymous> (/usr/lib/node_modules/grunt-cli/bin/grunt:41:20) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Function.Module.runMain (module.js:497:10)

正如你在.gitignore中写的https://github.com/gruntjs/grunt/issues/888 dist
希望有所帮助
发现这个工作，按照https://github.com/gruntjs/grunt/issues/888
rm -rf node_modules/grunt npm install grunt
这也应该工作。
尝试重新安装节点模块。
- 删除node_modules文件夹
- 做
npm cache clean - 做
npm install
希望能帮助到你 ：）
这看起来像你的grunt模块之一是试图使用underscore.js，但它没有安装。 这应该解决你的问题：
npm install underscore
或者甚至更好，在你的package.json中添加下划线作为开发依赖：
{ <your existing stuff here> "devDependencies": { "underscore": "~1.5.2" } }
