Error "Package does not have LinearAlgebra in its dependencies" running `Pkg.test`

Hello!

I am trying to write my first Julia package (called “BEAM”), but keep getting an error when I run Pkg.test("BEAM"):

(BEAM) pkg> test BEAM
   Testing BEAM
 Resolving package versions...
ERROR: LoadError: ArgumentError: Package BEAM does not have LinearAlgebra in its dependencies:
- If you have BEAM checked out for development and have
  added LinearAlgebra as a dependency but haven't updated your primary
  environment's manifest file, try `Pkg.resolve()`.
- Otherwise you may need to report an issue with BEAM
Stacktrace:

Now, as I understand it, LinearAlgebra is part of the std library, so why is Pkg.test complaining?
Or, how do I add std library packages to the [deps] section of Project.toml?

Calling Pkg.resolve doesn’t do much:

(BEAM) pkg> resolve
 Resolving package versions...
  Updating `~/w/BEAM/Project.toml`
 [no changes]
  Updating `~/w/BEAM/Manifest.toml`
 [no changes]

I’m using Julia 1.2.0. This is the list of using statements from the package sources:

using FileIO
using Images: Gray;
using IterTools: ivec;
using LinearAlgebra;
using SparseArrays: sparse;

# solver interface
using Convex: Variable, minimize, solve!;
using SCS: SCSSolver;

and this is the [deps] section from Project.toml:

[deps]
Convex = "f65535da-76fb-5f13-bab9-19810c17039a"
FileIO = "5789e2e9-d7fb-5bc7-8068-2c6fae9b9549"
Images = "916415d5-f1e6-5110-898d-aaa5f9f070e0"
IterTools = "c8e1da08-722c-5040-9ed9-7db0dc04731e"
SCS = "c946c3f1-0d1f-5ce8-9dea-7daa1f7e2d13"

Thanks for any explanation!

Running

(BEAM) Pkg> add LinearAlgebra

should do the trick.
Maybe SparseArrays would have to be added as well.

Yes, so there’s no need to download it, but you still need to list the dependency (as of Julia 0.7).

Many thanks, it actually did!

(I am sure I had tried it before posting, but for some reason, LinearAlgebra was not added to Project.toml. Somehow, my REPL must’ve ended up in an inconsistent state; quitting and starting a new session could have fixed it?)
