Bower not updating or installing - bower

Question

I've been trying to update moment.js (& several other plugins) using Bower, updating moment from 2.8.4 to 2.9.
I changed my bower.json file to be "moment": "2.x" (was ~2.8.3, I also tried ~2.8, then 2.x) & bower says it's cached and validated but running bower list shows 2.8.4 is still installed.
Whenever I try an update or install it goes through all my dependencies.
I then uninstalled moment (which worked), but now bower won't install it, bower list gives moment not installed.
I'm running the latest Bower 1.4.0.
My bower.json:
{
"name": "intranet",
"version": "1.12.35",
"authors": [
"SteB"
],
"license": "proprietary",
"ignore": [
"**/.*",
"node_modules",
"bower_components",
"test",
"tests"
],
"dependencies": {
"jquery": "~2.1",
"jquery-migrate": "~1.2",
"modernizr": "~2.8.3",
"moment": "2.x",
"respond": "~1.4.2",
"jquery-ui": "~1.11",
"chartjs": "~1.0.2",
"rickshaw": "~1.5.1",
"gmaps": "~0.4.14",
"d3": "~3.4.11",
"bootstrap-modal": "~2.2.5",
"kbwood_countdown": "~2.0.1",
"bootstrap": "2.3.2",
"footable": "2.0.1.5",
"bootstrap-maxlength": "~1.5.7",
"flot": "~0.8.3",
"jqplot": "*",
"scrollup": "2.4.*",
"fullcalendar": "1.6.4",
"bootstrap-switch": "~2.0.5",
"es5-shim": "~4.1",
"chosen": "~1.2",

"jquery.steps": "~1.1",
"jquery-cookie": "~1.4",
"typeahead.js": "~0.10.5",
"ladda": "~0.9.7"
},
"devDependencies": {},
"resolutions": {
"bootstrap": "2.3.2",
"jquery": "~2.1"
}
}

Answer 1

Delete yr previous "bower_components" folder or any other target installation location specified in ".bowerrc"
Use below bower.json (null to get latest version)
Run "bower install"
{
"name": "intranet",
"version": "1.12.35",
"authors": [
"SteB"
],
"ignore": [
"**/.*",
"node_modules",
"bower_components",
"test",
"tests"
],
"license": "proprietary",
"dependencies" : {
"jquery": null,
"jquery-migrate": null,
"modernizr": null,
"moment": null,
"respond": null,
"jquery-ui": null
}
}
Above will do fine. You need to check yr rest dependencies on bower bcz there naming seems to be incorrect
