Issue when installing Seurat: failing to load RcppHNSW

[Mariacherepkova]

Hi,

I was trying to install Seurat on MacBook (Intel i5) R version 4.4.2, and got the current error:

Error: package or namespace load failed for ‘RcppHNSW’ in .doLoadActions(where, attach): error in load action .__A__.1 for package RcppHNSW: Rcpp::loadModule(module = "HnswL2", what = TRUE, env = ns, loadNow = TRUE): Unable to load module "HnswL2": vector memory limit of 16.0 Gb reached, see mem.maxVSize() Error: loading failed Execution halted

I tried installing RcppHNSW through command line and anaconda - did not work.
Is there some memory limitation that would not allow me to install Seurat?

Thanks a lot!

This was resolved by installing a previous version of RcppHNSW:
remotes::install_github("jlmelville/rcpphnsw", ref = "v0.3.0")
