Hi,

You might try a different CRAN mirror to see if perhaps the rlang binary that you are getting is corrupted.

Looking at CRAN for the package, the results for rlang on what is supposed to be R release on macOS:

  https://cran.r-project.org/web/checks/check_results_rlang.html

shows a header indicating that R devel is being used, not R release:


https://www.r-project.org/nosvn/R.check/r-release-macos-x86_64/rlang-00check.html

So, I am not clear if there is a macOS binary build issue that may be resulting in a conflict of sorts.

A spot check of other CRAN packages (including my own) shows the same use of R devel for macOS, and not R release, so perhaps there is a wider issue going on with CRAN builds, unless I am missing something here.

Simon (cc'd now) may be able to address that issue.

Regards,

Marc Schwartz

I installed the new R version 4.1.0 on my (normal) Macbook, and
everything seemed to work fine until one of the packages depended on
the 'rlang' package and I got the following error:

     > library(rlang)
     Error: package or namespace load failed for ‘rlang’ in
     dyn.load(file, DLLpath = DLLpath, ...): unable to load
     shared object '/Users/hwb/Library/R/4.0/library/rlang/libs/rlang.so':
     dlopen(/Users/hwb/Library/R/4.0/library/rlang/libs/rlang.so, 6):
     Library not loaded:

     Referenced from: /Users/hwb/Library/R/4.0/library/rlang/libs/rlang.so
     Reason: image not found

So I removed 'rlang' and reinstalled it. There was no error message,
but when I tried to load it, the error message was:

     Error: package or namespace load failed for ‘rlang’ in
     get(Info[i, 1], envir = env): lazy-load database
     '/Users/hwb/Library/R/4.0/library/rlang/R/rlang.rdb' is corrupt
     In addition: Warning message:
     In get(Info[i, 1], envir = env) : internal error -3 in R_decompress1

One of my current applications relies on 'rvest' which depends on
'rlang'. For the moment I am using it from a Linux computer, but it's
quite unfortunate that I cannot run it from macOS as well.

I also uninstalled the new R version and reinstalled it, but nothing
changed. Could you give me a hint on what to do (or what I did wrong)?
