After update, I must have messed something up -- Error: Could not read package info file in
I used to be able to use `nimble`, so I must be *close*. What could be wrong?
```
$ nimble install --verbose c2nim
    Reading official package list
Downloading https://github.com/nim-lang/c2nim using git
    Setting Nim stdlib prefix to /Users/cdunn2001/repo/gh/Nim
    Setting Nim stdlib path to /Users/cdunn2001/repo/gh/Nim/lib
