Error: package or namespace load failed for 'RevoUtilsMath'

I'm getting a little bit crazy with this issue. I'm trying to install an R package using conda in my environment (python 2.7) in my home on a cluster (i.e. without root permissions). I firstly installed R in my env using: 

conda install -c r r=3.4

Then: 

conda install -c conda-forge python-igraph

(because igraph is required by my library of interest)

and finally: 

conda install -c conda-forge r-diffusionmap

Unfortunately when I launch R the following message appears:

Error: package or namespace load failed for 'RevoUtilsMath': .onLoad failed in loadNamespace() for 'RevoUtilsMath', details: call: NULL
error: Remove Microsoft R and then re-install. Be sure to select MKL libraries as an install option.

During startup - Warning message: package 'RevoUtils' was built under R version 3.4.3

What does it mean? How can I solve this?

Thank you in advance

All R packages on conda-forge (or Bioconda) are compiled against one single version or R for each new release branch (usually starting from patch 1, so 3.x.1, except for 3.4.3). This is due to ABI incompatibility problems.

Also note that defaults and conda-forge channels are (where) not binary compatible (although now they should be). And that since 2018 the default anaconda channel is distributing Microsoft R Open as default R, whether all packages from conda-forge should be preferably used with R from conda-forge.

You should be able to solve this issue by installing R using conda install -c conda-forge r-base.

I had this same issue after I installed some libraries (Rcpp included) in my root R, but not my conda environment (which screwed up conda). This would cause kernel death anytime a jupyter notebook running R was even opened.

The fix for me was:

  1. Uninstall Anaconda3
  2. Reinstall Anaconda3
  3. Reinstall all the libraries I needed (mostly just Bioconductor in R)

A few other issues popped up, like package inconsistencies, but I dealt with those as described here.
