I've install **puma-dev** at the latest Mojave 10.14.3 and got the following:
```
unexpected exit:
from /usr/local/bin/puma:25:in `'
```
On the white screen.
Logs are:
```

It seems like it tries to get gems from system preinstalled Ruby distribution, but I use rbenv.
How to make it work with rbenv?
