I feel like I must be overlooking something here.
When trying to run npm install on an existing project, I get the following error (from 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 ]
From what I can tell, grunt@0.4.2 should fulfill all these dependencies.
From this StackOverflow question, my understanding is that the packages rely on the following:
- grunt-concurrent@0.4.3 wants grunt@~0.4.0 (that is, grunt@0.4.*)
- grunt-contrib-sass@0.8.1 wants grunt@>=0.4.0
- grunt-autoprefixer@2.0.0 wants grunt@~0.4.2 (that is, grunt@0.4.*)
- grunt-webfont@0.5.4 wants grunt@~0.4.0 (that is, grunt@0.4.*)
- Peer grunt-purifycss@0.1.1 wants grunt@~0.4.5 (that is, grunt@0.4.*)
grunt@0.4.2 should match all of these dependencies, and yet npm is saying that it doesn't and failing the install. Is there something I'm overlooking?
