Hi, I’m having a persistent Pkg error while trying to create a new package. Like in other cases I:

1. Created a new repo [Webview.jl](https://github.com/joa-quim/Webview.jl)
2. `dev https://github.com/joa-quim/Webview.jl`
3. Try to use it

But it annoyingly it insists that the package is not installed when in fact my local copy is exactly equal to the Github repo.

```julia

```

No matter how many times I do what it requests (running instantiate) the error does not go away.

Can’t understand what is the difference with my other (local) packages that work.

This file [https://github.com/joa-quim/Webview.jl/blob/master/src/webview.jl](https://github.com/joa-quim/Webview.jl/blob/master/src/webview.jl) has an incorrect name (should be `Webview.jl`).

Thanks. But actually I only made it work by first cloning the repo and then doing  
`dev C:\\Users\\j\\.julia\\dev\\Webview`

Doing `dev URL` kept giving me the same error.

You probably had a stale clone ([https://github.com/JuliaLang/Pkg.jl/issues/465](https://github.com/JuliaLang/Pkg.jl/issues/465)) so it is likely that removing `~/.julia/clones` and then `dev URL` would work.

Maybe, but had cleaned that dir before (did lots of trials before posting)
