Warning: Task "clean:server" not found

If I use any grunt task it throws this error. Someone on the irc channel said it was possible that my gruntfile was corrupt, but there is no information on the internet that could help me learn to fix this issue

Warning: Task "(some task)" not found. Use --force to continue.

Aborted due to warnings.

If I do grunt serve the error says that task "clean:server can be found".
but my gruntfile contains clean server

clean: {
dist: {
files: [{
dot: true,
src: [
'.tmp',
'<%= config.dist %>/*',
'!<%= config.dist %>/.git*'
]
}]
},
server: '.tmp'
}

Answer

May be you accidentally deleted some file in the node_modules/grunt-contrib-clean directory. Delete this dir and repeat the npm install. I also detected the problem and this worked for me.
