When I am developing a package or entering in dev environment using  
`dev package_name`  
I am getting the following error:

```julia
ERROR: The following package names could not be resolved:
 * package_name (not found in project, manifest or registry)

```

you can dev it with URL though, just not by the name alone.  
`dev your_github_repo_url`
