How to properly kpm cache clean?

Question

I'm trying to use ASP.NET 5 and their new command line tools (kpm, kvm, etc) on my Mac (OSX 10.10.1) but I'm having problems with kpm install. The install generally works fine, except when a new version of a package was just published, kpm says it is unable to locate the package, e.g.:

~/Projects/myproj: kpm install My.Custom.Pkg 1.0.4
  CACHE https://www.myget.org/F/aspnetvnext/api/v2/FindPackagesById()?Id='My.Custom.Pkg'
  CACHE https://www.nuget.org/api/v2/FindPackagesById()?Id='My.Custom.Pkg'
  CACHE http://tools.production.com/nuget/FindPackagesById()?Id='My.Custom.Pkg'
My.Custom.Pkg.1.0.4 was added to project.json.

  CACHE https://www.myget.org/F/aspnetvnext/api/v2/FindPackagesById()?Id='My.Custom.Pkg'
  CACHE https://www.nuget.org/api/v2/FindPackagesById()?Id='My.Custom.Pkg'
  CACHE http://tools.production.com/nuget/FindPackagesById()?Id='My.Custom.Pkg'
Resolving complete, 4286ms elapsed
Unable to locate My.Custom.Pkg >= 1.0.4

If I wait about 20 minutes and kpm install My.Custom.Pkg 1.0.4 again, it will find the new package version. This seems to be a problem with the kpm cache because I can open up Visual Studio on my Windows machine and find the newly published package instantly.

My question is: is there a way to forcefully clear the local kpm cache? And not the ~/.kpm/packages directory either... that doesn't seem to help this use case. There seems to be another internal http cache when it's making the GET request to the various NuGet feeds.

Use the --no-cache argument for kpm install:

kpm install --no-cache My.Custom.Pkg 1.0.4
