Unknown filetype

[martinos]

I am on MacOs Sierra and when I run the command I get the following error message:

error: unknown file type: /Users/me/.elm-install/github.com/elm-lang/html/./.git/tags.34360.

Here is the call stack

I get the same error when using the npm version.

It seems that this error is not bound to a specific package.

It seems that the file that the gem is trying to copy does not exist anymore. Is there some kind of threading in the library?

I just had this same problem - how does your dependency sources look? I was having this when I used the string reference to the repo, but it seems to have gone away when I used the object format

        "publisher/package": {
            "url": "git@bitbucket.org:publisher/package.git",
            "ref": "master"
        }

I'm guessing something about the tags. For me, the error always occurred for a separate dependency but was actually triggered by the repo dependency.

Edit: Nevermind, it broke again. Honestly, it seems almost random.
