Hi, i was trying to make some modifications to the laplaceredux package but i am having some issues with the environment. everything worked until i tried to add MLJBase to the environment, now julia tells me

> ERROR: LoadError: ArgumentError: Package LaplaceRedux does not have MLJBase in its dependencies:

when i do Pkg.status() i get

i tried with update, instantiate and resolve too but nothing works. I am honestly confused on how the julia envs work…  
why does it even matter that laplaceredux does not have MLJBase in its dependencies?

First, please clarify what “the environment” is.  
It looks like you are in `LaplaceRedux.jl\docs\Project.toml`.  
It is separate from `LaplaceRedux.jl\Project.toml`.

Did you solve the trouble?  
If solved, set the solution flag.

If not, please clarify the following:

- Do you want to change either (or both) `LaplaceRedux` itself or its documentation?
- Have you added `MLJBase` in `LaplaceRedux.jl\Project.toml`?
- Are you `using` `MLJBase` in `LaplaceRedux.jl\src\`?
- Are you `develop`ing `LaplaceRedux` in the default environment or in `LaplaceRedux.jl\docs\Project.toml`?

no, i didn’t.  
I am using the /docs env to learn how the project works because i don’t want to mess the main env. I just typed in Pkq add MLJBase.

The following is not your fault, but should be noted.

- `LaplaceRedux.jl/docs/Project.toml` has `LaplaceRedux` in `[deps].`
- LaplaceRedux.jl has `docs/Manifest.toml`.
  - [LaplaceRedux.jl/docs/Manifest.toml at main · JuliaTrustworthyAI/LaplaceRedux.jl · GitHub](https://github.com/JuliaTrustworthyAI/LaplaceRedux.jl/blob/main/docs/Manifest.toml)

Perhaps you can try deleting (renaming) Manifest.toml.

**Edit:** I could not reproduce the problem with LaplaceRedux v0.2.0 and julia 1.10.2. Please list everything you have done.

God’s only knows at this point. I have tried a lot of things

can I simply tell Julia to delete all the packages and start the env from zero?

Hmm, I am not a native English speaker, so I may not fully understand the nuances, but I felt your following statement was saying “no”.

> Are you `using` `MLJBase` in `LaplaceRedux.jl\src\`?

> [@Rockdeldiablo](#):
>
> I am using the /docs env to learn how the project works because i don’t want to mess the main env. I just typed in Pkq add MLJBase.

So,

> Have you `add`ed `MLJBase` in `LaplaceRedux.jl\Project.toml`?

Literally, the error message says:

> Package `LaplaceRedux` does not have `MLJBase` in its dependencies

The “its” means “`LaplaceRedux`’s”.

**Edit:**

> [@Rockdeldiablo](#):

> God’s only knows

[Git](https://git-scm.com/) bless you.

I have added `MLJBase` to `LaplaceRedux/Project.toml` and added `using MLJBase` to `src/LaplaceRdeux.jl`, but the problem does not reproduce.  
In the first place, `LaplaceRedux` indirectly depends on `MLJBase` and adding `MLJBase` to the dependency should not cause any problems.

So, you are saying that the error message is misdirected.  
I am sorry I could not help you.

yes, that’s what i tried yesterday. i deleted manifest and toml and started reinstalling the packages one after one. I think it’s a compatibility issue: whenever i reinstall taijaplotting mljbase goes back from version 1.2 to 0.21

there is no need to be an ass. Anyway when i removed taijaplotting and updated the packages the error disappeared. I don’t know why and i don’t care as long as it works for what i need.
