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...

What happens if you do ```julia ENV["R_HOME"] = "/public/home/xuruiqiang/miniconda3/envs/RTIGER/bin/R" using Pkg Pkg.build(PackageSpec(name="RCall", version="0.13.6")) ``` ?

One more idea: ```sh (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")) ```

I think this setup is also desirable behavior -- I think it makes sense to require direct dependency for something you care enough about the details of to set a...

Thanks for proving an MWE! Looking at the NLopt docs, I'm not sure [PRAXIS](https://nlopt.readthedocs.io/en/latest/NLopt_Algorithms/#praxis-principal-axis) is an algorithm I'd recommend: > This algorithm was originally designed for unconstrained optimization. In NLopt,...

The problem in the MWE is that the optimizer winds up oscillating around the optimum. ``` ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀objective⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ┌────────────────────────────────────────┐ 11.0467 │⠀⠀⢰⠀⠀⡖⢲⠀⠀⡆⠀⢠⡆⠀⢰⠒⡆⠀⢰⠀⠀⡆⠀⢠⠒⡆⠀⢠⡆⠀⢰⠀⠀⡖⢲⠀⠀⡆⠀⢠│ │⠀⠀⢸⠀⠀⡇⢸⠀⠀⡇⠀⢸⡇⠀⢸⠀⡇⠀⢸⠀⠀⡇⠀⢸⠀⡇⠀⢸⡇⠀⢸⠀⠀⡇⢸⠀⠀⡇⠀⢸│ │⠀⠀⣾⠀⠀⡇⢸⠀⠀⣷⠀⢸⡇⠀⡎⠀⡇⠀⣾⠀⠀⣷⠀⢸⠀⢱⠀⢸⡇⠀⣾⠀⠀⡇⢸⠀⠀⣷⠀⢸│ │⠀⠀⣿⠀⠀⡇⢸⠀⠀⣿⠀⢸⡇⠀⡇⠀⡇⠀⣿⠀⠀⣿⠀⢸⠀⢸⠀⢸⡇⠀⣿⠀⠀⡇⢸⠀⠀⣿⠀⢸│ │⠀⠀⡇⡇⢸⠀⠀⡇⢸⢸⠀⢸⡇⠀⡇⠀⡇⠀⡇⡇⢸⢸⠀⢸⠀⢸⠀⢸⡇⠀⡇⡇⢸⠀⠀⡇⢸⢸⠀⢸│ │⠀⠀⡇⡇⢸⠀⠀⡇⢸⢸⠀⡸⢇⠀⡇⠀⢇⠀⡇⡇⢸⢸⠀⡸⠀⢸⠀⡸⢇⠀⡇⡇⢸⠀⠀⡇⢸⢸⠀⡸│ │⠀⠀⡇⡇⢸⠀⠀⡇⢸⢸⠀⡇⢸⠀⡇⠀⢸⠀⡇⡇⢸⢸⠀⡇⠀⢸⠀⡇⢸⠀⡇⡇⢸⠀⠀⡇⢸⢸⠀⡇│ │⠀⢠⠃⡇⢸⠀⠀⡇⢸⠘⡄⡇⢸⢠⠃⠀⢸⢠⠃⡇⢸⠘⡄⡇⠀⠘⡄⡇⢸⢠⠃⡇⢸⠀⠀⡇⢸⠘⡄⡇│ │⠀⢸⠀⡇⢸⠀⠀⡇⢸⠀⡇⡇⢸⢸⠀⠀⢸⢸⠀⡇⢸⠀⡇⡇⠀⠀⡇⡇⢸⢸⠀⡇⢸⠀⠀⡇⢸⠀⡇⡇│ │⠀⢸⠀⢱⡎⠀⠀⢱⡎⠀⡇⡇⢸⢸⠀⠀⢸⢸⠀⢱⡎⠀⡇⡇⠀⠀⡇⡇⢸⢸⠀⢱⡎⠀⠀⢱⡎⠀⡇⡇│ │⠀⢸⠀⢸⡇⠀⠀⢸⡇⠀⡇⡇⢸⢸⠀⠀⢸⢸⠀⢸⡇⠀⡇⡇⠀⠀⡇⡇⢸⢸⠀⢸⡇⠀⠀⢸⡇⠀⡇⡇│...
