Difficulty installing RCall on a low version of julia

[isaamael]

Hi ！
I had to install RCall in Julia 1.4.0 because of the R package dependency, I ran the following code, however I'm having trouble resolving the error

julia> ENV["R_HOME"] = "~/miniconda3/envs/RTIGER/lib/R"
"~/miniconda3/envs/RTIGER/lib/R"

julia> Rhome = "~/miniconda3/envs/RTIGER/lib/R"
"~/miniconda3/envs/RTIGER/lib/R"

julia> libR = "~/miniconda3/envs/RTIGER/lib/R/lib/libR.so"
"~/miniconda3/envs/RTIGER/lib/R/lib/libR.so"

julia> Pkg.build(PackageSpec(name="RCall", version="0.13.2"))
   Building Conda → `~/.julia/packages/Conda/sDjAP/deps/build.log`
   Building RCall → `~/.julia/packages/RCall/ffM0W/deps/build.log`

R is installed via conda and I have determined that "~/miniconda3/envs/RTIGER/lib/R" is the folder.
I specified the RCall version, because the newer versions of RCall don't work on Julia before 1.6.0+, I don't know if 0.13.2 will, I didn't find instructions corresponding to the julia version! I'd like to try it, but the installation comes first!

Seeking help !

Instead of using the ~, can you use the full path? ~ is something that Bash provides and it's not necessarily recognized at the file system level. Looking at the rest of your error message, you need something like

julia> ENV["R_HOME"] = "/public/home/xuruiqiang/miniconda3/envs/RTIGER/lib/R"

Dear Developer, @palday
Firstly, I apologize for the late reply, I’ve been tied up with too many trivial matters!
I tried the method you suggested, however, the same error still appears.

In addition, I also tried several other methods, all to no avail.
As you can see, R is in the conda environment, and Julia is in the system environment variables. I need to install RCall in Julia in order to use a specific R package.
I don’t know if you can provide any other suggestions to help identify where the problem lies and how to solve it.
Please forgive me as a programming novice and Julia newbie.
Any advice is needed !

What happens if you do

ENV["R_HOME"] = "/public/home/xuruiqiang/miniconda3/envs/RTIGER/bin/R"
using Pkg
Pkg.build(PackageSpec(name="RCall", version="0.13.6"))

?

emmm......it dose not work

julia> ENV["R_HOME"] = "/public/home/xuruiqiang/miniconda3/envs/RTIGER/bin/R"
"/public/home/xuruiqiang/miniconda3/envs/RTIGER/bin/R"
julia> using Pkg
julia> Pkg.build(PackageSpec(name="RCall", version="0.13.6"))
   Building Conda → `~/.julia/packages/Conda/sDjAP/deps/build.log`

Any chance it's a problem with the julia install?

[palday]

One more idea:

(RTIGER) [xuruiqiang@login2 ~]$ LD_LIBRARY_PATH="/public/home/xuruiqiang/miniconda3/envs/RTIGER/lib/R/lib/:$LD_LIBRARY_PATH" julia
julia> ENV["R_HOME"] = "/public/home/xuruiqiang/miniconda3/envs/RTIGER/lib/R"
julia> using Pkg
julia> Pkg.build(PackageSpec(name="RCall", version="0.13.6"))

[isaamael]

still erro.
