sudden errors in loading packages

[majazaloznik]

I'm getting the following error in a renv initialised project:

Error: package or namespace load failed for ‘RefManageR’ in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object '/home/mz/.local/share/renv/cache/v4/R-3.6/x86_64-pc-linux-
gnu/stringi/1.4.3/113506f116db9dd5bd1caf46884e0647/stringi/libs/stringi.so':
  libicui18n.so.64: cannot open shared object file: No such file or directory

Same thing happened with the strinr package in another renv project.

The packages load no problem outside renv projects. I've tried removing and reinstalling them in the renv projects, but the same thing happpens.

I have renv 0.9.2, sessionInfo is bellow

  libicui18n.so.64: cannot open shared object file: No such file or directory

My best guess:

1. You installed stringi;
2. The version of libicui18n.so was upgraded on your system;
3. stringi retains a reference to the old version of libicu (libicui18n.so.64), but that no longer exists.

You'll likely need to reinstall the stringi package.

Sorry I wasn't able to be systematic about what worked here and what didn't. I uninstalled and reinstalled a bunch of things, and reinitialised renv a few times as well, and not all seems fine.

I only opened this here because throughout this I never had any problems with loading any packages in any non-initialised repos or projects. But there was a similar issue with every renv project I had, so I assumed it was connected somehow.

An old issue, but I run into this fairly frequently due to the fact that I'm using an optimised BLAS (OpenBLAS to be precise). The TL;DR version is that you need to re-install any linked packages after a BLAS upgrade, including those in an renv cache. More details here.

On the plus, you should be able to use this script to fix this issue automatically in any renv-based project. (EDIT: Actually, I think you'll need to amend the script since it will automatically install the most recent versions of any identified libraries...)
