issues loading prophet in R 4.0.2 #1604

Closed hlydecker closed 4 years ago

hlydecker commented 4 years ago

When attempting to load prophet, I get these errors:

library(prophet)
Error: package or namespace load failed for ‘prophet’ in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/Library/Frameworks/R.framework/Versions/4.0/Resources/library/prophet/libs/prophet.so':
  dlopen(/Library/Frameworks/R.framework/Versions/4.0/Resources/library/prophet/libs/prophet.so, 6): Library not loaded: @rpath/libtbb.dylib
  Referenced from: /Library/Frameworks/R.framework/Versions/4.0/Resources/library/prophet/libs/prophet.so
  Reason: image not found

I've checked and prophet.so and libtbb.dylib are both in the correct locations. I'm using the most recent releases of R and Rstudio on macOS 10.15.5.

This just came up in #1601 too. My only thought there was to try re-installing from source? install.packages("prophet", type="source"). Does that do anything?

@bletham that worked; numerous warnings were generated, but they seem to all be from RcppEigen and StanHeaders rather than prophet. Thanks!
