Calling aura with C command and -v option to clean vcs cache, fails with unhandled exception when vcspath does not yet exist (/var/cache/aura/vcs by default):

sudo aura -Cv aura: /var/cache/aura/vcs: getDirectoryContents:openDirStream: does not exist (No such file or directory)

Expected behavior: such case would be sanely handled

My quickfix solution folows:

Thanks for the report. Surely some other process (perhaps package installation involving a VCS package) creates that the directory initially, and -Cv here assumes it exists. I'll look into it.

Note that this isn't an issue in Aura 4, which ensures that all of its support directories exist on startup.

Sorry about the wait on this. Yes, it seems like the path is only created if some -git (etc.) package has been built at least once.

I will be releasing Aura 4 soon. Before I do that, I will make one final release of the Aura 3 series, which will include this fix, in case that's the version you want to keep using. Mind you, Aura 4 has many more new goodies.

Thanks again for your patience.
