I went back to a project I haven’ touched in about a month today and, voila, rstan is no longer working. The only related thing I’ve done on the cluster where I’m working on this is a failed attempt to install rstanarm from github, so I may have done something there.
Here is the the error message I got:
Error: package or namespace load failed for rstan in dyn.load(file, DLLpath = DLLpath, ...): unable to load shared object '/home/x_tomli/R/x86_64-pc-linux-gnu-library/3.6.3/V8/libs/V8.so': libv8.so.3: cannot open shared object file: No such file or directory Execution halted srun: error: n641: task 0: Exited with exit code 1
I also tried the standard stan example on the log-in node, which caused RStudio to crash. Here is a screen shot of the incident:
Here is info about the platform etc:

I’ve tried reinstalling rstan, V8 and rcpp. Any suggestions of what else to try? I’ve seen other having problems lately that were solved by upgrading to a newer R, but 3.6.3 is the most recent available version on the cluster on which I’m working.
