Error in loading DESeq2

Hi all

I have been using DESeq2 no problem for a while including earlier today

Now, whenever I load it I get the below error message. I tried re-downloading DESeq2 and restarting my computer and R, but no dice.

Any thoughts?

Error: package or namespace load failed for ‘SummarizedExperiment’ in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/Library/Frameworks/R.framework/Versions/4.2/Resources/library/Matrix/libs/Matrix.so':

Error: package ‘SummarizedExperiment’ could not be loaded

I also tried to download SummarizedExperiment package, but this did not help load DESeq2.

The error message seems to be complaining about a fortran compiler, which would be a system and not R dependency. Try (re)installing gcc on your computer.

If you're using some debian flavor of linux you could install build-essential which includes gcc and a bunch of other useful compilers.

sudo apt-get update
sudo apt-get install build-essential

Thanks, I tried to re-download gfortran but that did not seem to work

Any other thoughts?

Thanks!

Edit: I use MacOS not linux

There is a specific section on CRAN that covers gfortran and other required tools for macOS: https://mac.r-project.org/tools/

Please go through that, be sure that XCode and the gfortran compiler are properly installed as described there.

Thanks all as an update

I think I updated my computer and my Fortran libraries moved

I used this command line code to fix:

locate libgfortran.5.dylib

returns:

/usr/local/gfortran/lib/libgfortran.5.dylib

corrected by:

ln /usr/local/gfortran/lib/libgfortran.5.dylib /usr/local/lib/libgfortran.5.dylib
