Could not find project file for dev'ed package

[dawbarton]

I've just been trying out Julia 1.4.0-RC1 and noticed that I am unable to dev my own registered packages.

With a clean environment on Julia 1.3.1

ERROR: could not find project file in package at nothing

However, I am able to dev some other packages. Is this an intentional change?

BTW: this is on Linux.

Yes, you need a project file.

Something as simple as this will work:

name = "BarycentricInterpolation"                                                                                  
uuid = "7781f4b9-0ba3-4b3e-a982-d971b817e3a7"                                                                      
version = "0.1.0"                                                                                                  

There are full instructions on how to transfer from REQUIRE to Project.toml: https://github.com/JuliaRegistries/Registrator.jl#transitioning-from-require-to-projecttoml

Ah, of course. I'd forgotten that this package was done before project files were a thing.
