In the pkg mode of the Julia 1.0 REPL I can do the following to get add a specific branch of my unregistered package:

`(v1.0) pkg> add https://github.com/JuliaRheology/RHEOS.jl#v1compat`

However, if I want to dev a specific branch:

`(v1.0) pkg> dev https://github.com/JuliaRheology/RHEOS.jl#v1compat`

I get:

`ERROR: invalid token`

**Is it possible to `dev` a package with a non-master branch?**

Thanks

You can `dev` and then just change the branch with e.g `git`.

My master branch is still Julia 0.6 so I get the following error:

```julia
ERROR: Unsatisfiable requirements detected for package JLD [4138dd39]:

```

Maybe there’s a way to ignore errors? If possible I’d like to avoid changing the master branch for now.

Are you using 1.0.1? There’s been some fixes there that might help this.

When using `dev` the normal julia compatibility that is used in `add` should be disregarded…

I wonder if I’ve messed something up here by adding the specific branch too?

Some further info, now when I navigate to `\.julia\dev\RHEOS` there is a folder there but when I type `git branch` it just shows the `master` branch.

And just in case it is helpful for diagnosis I’m on Windows 7 (64 bit) and installed Julia from .exe (not from source).

This is the expected behavior.

Ah I thought that all branches should be cloned in with the `dev` command and Kristoffer’s comment was saying I should be able to just checkout the branch. I understand now he meant I need to fetch it in. I did the following:

`git fetch origin v1compat:v1compat`

which seems to have worked. However it still seems counter-intuitive to yield and error yet still produce what in my case is basically the desired result?

**EDIT:** The files in the directory have updated as expected but when I try `using RHEOS` I get the following Error message:

```julia

julia> using RHEOS
ERROR: ArgumentError: Package RHEOS not found in current path:
- Run `import Pkg; Pkg.add("RHEOS")` to install the RHEOS package.

Stacktrace:
 [1] require(::Module, ::Symbol) at .\loading.jl:820

```

And although I was sure it wouldn’t work, just for full clarity I did try the REPL suggestion, which didn’t work as it is not a registered package:

```julia
julia> import Pkg

julia> Pkg.add("RHEOS")
  Updating registry at `C:\Users\louis.kaplan\.julia\registries\General`
  Updating git-repo `https://github.com/JuliaRegistries/General.git`
ERROR: The following package names could not be resolved:
 * RHEOS (not found in project, manifest or registry)
Please specify by known `name=uuid`.

```

Also to note, when I `add` RHEOS (correct branch) and type `using RHEOS` it works fine (I have removed RHEOS since then to try and focus on getting the `dev` version working without any confusion).

Thanks. Just to check, did you mean disregarded by the user or disregarded by Julia?

OK, finally got it working.

I did the following

1. In Julia `pkg` mode: `dev https://github.com/JuliaRheology/RHEOS.jl`
2. Exited Julia
3. `git fetch origin v1compat:v1compat` (in the dev/RHEOS directory)
4. `git checkout v1compat`
5. In Julia `pkg` mode: `dev https://github.com/JuliaRheology/RHEOS.jl`

In the first step I get the error message described above but it still downloads the folder. In the last fifth step I do not get any error message and I can now do `using RHEOS`. To emphasise, I could not do `using RHEOS` at any point until completing all these steps.

Is this the intended behaviour? Seems a little counter-intuitive (to a fairly inexperienced Julia user). If it is I may try add a PR to the documentation to add info on this.

Can you just do `resolve` at the pkg prompt instead of the final `dev`? You have to do this if dependencies change via non-pkg operations (e.g. editing a file or running a git command).

Trying that now (so as my above post steps 1 - 4, and then `resolve` instead of step 5), then back to normal Julia REPL:

```julia
julia> using RHEOS
ERROR: ArgumentError: Package RHEOS not found in current path:
- Run `import Pkg; Pkg.add("RHEOS")` to install the RHEOS package.
