I have been unable to use the include method on Neptune.jl exclusively, below is my terminal session.

You’re creating a new folder. You need to remove the `.jl` in your `activate`.

EDIT: Oh maybe I got this wrong…

What are the filenames in your folder

```julia
Neptune.jl/src

```

perhaps the source file is `neptune.jl` with a lowercase n.

What are you trying to do? Why not just do:

```julia
] activate Neptune
using Neptune

```

?

The error you see is from executing [Neptune.jl/Neptune.jl at 5f95cb444b02155d2dbdbd76e4f245896e68da20 · compleathorseplayer/Neptune.jl · GitHub](https://github.com/compleathorseplayer/Neptune.jl/blob/5f95cb444b02155d2dbdbd76e4f245896e68da20/src/Neptune.jl#L15), as apparently `pathof` a module loaded with `include` is not defined, hence returning `nothing`.

It’s just that this does not create a folder with a `src/` for me, and so I can’t reproduce the error so I’m not sure… More likely that others, like @mauro3 above, know what’s going on 🙂

You could always clone the repository  
git clone [GitHub - emmettgb/Neptune.jl: Simple (Pluto-based) non-reactive notebooks for Julia](https://github.com/emmettgb/Neptune.jl)

I have been doing so through Pkg, adding and updating – not too bad, but constant commits with any alterations…

Have you tried without the `.jl` as suggested by @mauro3 and myself? While the packages have the `.jl` extension on GitHub, I believe all your local package repositories in `dev/` should appear without the `.jl` extension if you `add`ed or `dev`ed them.

Yes, but the environment is not so much what I am worried about, as status() and update() seem to have worked fine. The include() call is where I am getting the error, it is like the src/Neptune.jl file does not exist. Calling src/Neptune as well yields no difference as wekk of course. It is almost as if Julia is unaware that the file exists.

I mean instead of `cd`ing into `dev/Neptune.jl`, have you tried `cd`ing into the correct `dev/Neptune`?

Have you read my post above? It finds the file but then errors in the line linked to above. Apparently it is not made to be `included` but only loaded by `using` or `import`. Alternatively, if you must `include` you will need to update that line of code.
