Tolerate object-valued bower license property

[pkaminski]

I found at least one Bower package (serialized-lru-cache) that defines its license as:

  "license": {
    "type": "MIT",
    "url": "http://github.com/jmendiara/serialized-lru-cache/raw/master/LICENSE"
  },

No idea if it's spec-compliant or not, but it will crash bower-license and it's a simple fix, so...

I think this is a "bug" in the bower-config of serialized-lru-cache. This type of license definition is not in the spec. This issue should be fixed there and not here.
Thanks anyway for finding and reporting!

I agree, I don't think the library should be parsing arbitrary specs, but the crashing is not good.

I think what makes sense is simply to check for type:

if (typeof bowerData.license === 'string'){
  moduleInfo.licenses = moduleInfo.licenses.concat(bowerData.license)
}

OK, I opened a PR against serialized-lru-cache: jmendiara/serialized-lru-cache#1

FWIW, the spec you pointed to also allows an array of strings for the license value, so the type check should probably allow for that.

Fixed in jmendiara/serialized-lru-cache#1
