Pkg.test does not recognize package dependencies

General Usage

Hello,

I am writing a Julia package. I already have a few releases, so I got the basics working. I just added another function and I added the new dependency on Statistics, like so:

(Planets) pkg> resolve
 Resolving package versions...
  Updating `Project.toml`
 [no changes]
  Updating `Manifest.toml`
 [no changes]

The first time I ran this Project.toml and Manifest.toml were updated so that now they include the Statistics package. For example, Manifest.toml contains this bit:

[[Statistics]]
deps = ["LinearAlgebra", "SparseArrays"]
uuid = "10745b16-79ce-11e8-11f9-7d13ad32a3b2"

So now I want to run the new tests that I’ve added, and that’s where I run into trouble. The test feature doesn’t realize that I’ve already added Statistics as a dependency:

Varda ~/Science/Planets.jl % julia

(Planets) pkg>

I’m really stuck here. Can anyone figure what’s going on? It’s complaining that I have not added Statistics to the list of dependencies, but it’s right there in the .toml files. Does anyone know what to do here?

Cheers,
Daniel

What does

(Planets) pkg> st

say?

Can you show your full Project file?

Hmm… st is missing Statistics:

(Planets) pkg> st
Project Planets v0.1.0
    Status `Project.toml`
  [336ed68f] CSV v0.4.1
  [a93c6f00] DataFrames v0.14.1
  [e1d29d7a] Missings v0.3.1

It looks like Statistics was added to Manitfest.toml but not to Project.toml. Can you explain the difference between those two files?

name = "Planets"
uuid = "7a3fd1c8-cccc-11e8-1991-ff9663c7a777"
authors = ["Daniel Carrera <dcarrera@gmail.com>"]
version = "0.1.0"

[deps]
CSV = "336ed68f-0bac-5ca0-87d4-7b16caf5d00b"
DataFrames = "a93c6f00-e57d-5684-b7b6-d8193f3e46c0"
Missings = "e1d29d7a-bbdc-5cf2-9ac0-f12de2c33e28"

[compat]
julia = "0.7"

[extras]
Test = "8dfed614-e22c-5e08-85e1-65c5234f0b40"

[targets]
test = ["Test"]

So I just added Statistics = "10745b16-79ce-11e8-11f9-7d13ad32a3b2" inside the [deps] section and now I’m getting different errors that don’t seem to have anything to do with dependencies.

My guess is you added it to the wrong environment.

Project is similar to REQUIRE, you list what you depend on.

Manifest is like a snapshot of the result of the resolution algorithm. It records what packages depends on what and what versions everything is installed at.

In order for your package to be able to load a dependency, it needs to exist in the Project.

So what you need to do here is likely just Pkg.add("Statistics").
