npm依赖项未得到满足(即使它们应该得到满足?）

我觉得我一定忽略了一些东西。

当尝试在现有项目上运行npm安装时，我收到以下错误（来自npm debug.log）：

76 error Windows_NT 6.1.7601
77 error argv "C:''Program Files''nodejs''node.exe" "C:''Program Files''nodejs''node_modules''npm''bin''npm-cli.js" "install"
78 error node v4.4.2
79 error npm  v2.15.0
80 error code EPEERINVALID
81 error peerinvalid The package grunt@0.4.2 does not satisfy its siblings' peerDependencies requirements!
81 error peerinvalid Peer grunt-concurrent@0.4.3 wants grunt@~0.4.0
81 error peerinvalid Peer grunt-contrib-sass@0.8.1 wants grunt@>=0.4.0
81 error peerinvalid Peer grunt-autoprefixer@2.0.0 wants grunt@~0.4.2
81 error peerinvalid Peer grunt-webfont@0.5.4 wants grunt@~0.4.0
81 error peerinvalid Peer grunt-purifycss@0.1.1 wants grunt@~0.4.5
82 verbose exit [ 1, true ]

据我所知，grunt@0.4.2应该满足所有这些依赖关系。

从这个StackOverflow问题中，我的理解是包依赖于以下内容：

• grunt-concurrent@0.4.3想要咕哝@~0.4.0（也就是说，grunt@0.4.*)
• grunt-contrib-sass@0.8.1想要咕哝@>=0.4.0
• grunt-autoprefixer@2.0.0想要咕哝@~0.4.2（也就是说，grunt@0.4.*)
• grunt-webfont@0.5.4想要咕哝@~0.4.0（也就是说，grunt@0.4.*)
• 对等grunt-purifycss@0.1.1想要咕哝@~0.4.5（也就是说，grunt@0.4.*)

grunt@0.4.2应该匹配所有这些依赖项，但npm说它不匹配，安装失败。有什么东西我在俯瞰吗？
