Hello,
System: Kubuntu-18.04.4 LST
Julia: JuliaPro_v1.4.0-1
For my first steps in Julia, I am using Ben Lauwens book.
I would like to install ThinkJulia using the command as suggested in the book, i.e:
add https://github.com/BenLauwens/ThinkJulia.jl
However, in (@v1.4) pkg>, I obtain this error:
ERROR: could not find project file in package at https://github.com/BenLauwens/ThinkJulia.jl
Could you tell me how to circumvent this error?
Thank you in advance.
Thierry
It seems Julia 1.4 dropped support for REQUIRE files. I created an issue here https://github.com/JuliaLang/julia/issues/35345.
In the meantime, I checked that the package installation does work under Julia 1.3.1, so you can use that instead.
Thank you for your reply, jebej.
I installed JuliaPro-1.0.5-2 (LTS) and, indeed, I was able to ad hoc packages. 
So, in conclusion to the thread you started on https://github.com/JuliaLang/Pkg.jl/issues/1745, it appears that Ben Lauwens should add a Project.toml file to his repository
Done!
Many thanks.
Julia-1.4 works perfectly.
