Problem using Documenter.jl

I am doing a project in julia, and was attempting to use doctest.jl for documentation. I was following the intstructions on github, and had everything working until running make.jl from the docs directory. Here is the code I used:

julia> cd("C:\\Arya's desktop\\Arya\\Programming\\Julia\\ConsistentSampler\\docs")

julia> make.jl
ERROR: UndefVarError: make not defined

Here is my folder structure:
C:\Arya’s desktop\Arya\Programming\Julia\ConsistentSampler\src: consistent_sampler.jl, demo_consistent_sampler.jl
C:\Arya’s desktop\Arya\Programming\Julia\ConsistentSampler\docs:, make.jl
C:\Arya’s desktop\Arya\Programming\Julia\ConsistentSampler\docs\src: empty

Could anyone please let me know what to do?

You should use include("make.jl").

A full working example is available here:

Follow my instructions here:

it is better to have two make.jl and makeLocal.jl. makeLocal.jl can be the same as this link’s code:

But for make.jl, we should remove 1st 4 lines of code

My instructions are as follows:

To build the documentation locally

Running inside Julia REPL:

cd to docs folder cd("path to docs\\MatLang\\docs") and run the following command:


Running inside OS Terminal:

cd to docs folder using OS terminal and run the following command (Julia path should be added to OS path):

julia --color=yes makeLocal.jl

Alternatively, you can use make.jl but using the following method:
cd to package folder using OS terminal and run the following commands:

julia -e 'using Pkg; Pkg.activate(); push!(LOAD_PATH, pwd());'
julia --project=docs/ -e 'using Pkg; Pkg.activate();  push!(LOAD_PATH,pwd());'

julia --project=docs/ -e 'using Pkg; Pkg.develop(PackageSpec(path=pwd())); Pkg.instantiate();'
julia --project=docs/ --color=yes docs/make.jl

To build the documentation online using Travis

Use this Travis script:

- julia --project=docs/ -e 'using Pkg; Pkg.develop(PackageSpec(path=pwd()));
- julia --project=docs/ docs/make.jl

Thank you so much. It works. You are a life saver!:pray:

This is generally not needed, you can just start your julia process with that project activated, eg

julia --project=@. make.jl

when you are in docs/.


Neither of those lines does anything persistent, and are not needed.

Without those, user will run into errors:
Ruining 3rd line without the first two:

julia --project=docs/ -e 'using Pkg; Pkg.develop(PackageSpec(path=pwd())); Pkg.instantiate();'

This gives an error:

The code that I wrote works for any situation, no matter if the package is installed or not. That is what a beginner needs.

No they don’t. The error you’re seeing is because you were already in the docs/ directory when you called that line. The error is thrown by the Pkg.develop call, which tries to develop the docs/Project.toml (implying that pwd() was already docs/). That fails as it is not a package and is missing the name entry.

Yes, the implicit assumption is that you have deved your package in the global environment.


for the recommended setup.
