rlang and the new R version 4.1.0

When R4.0 came out,  someone on R-Bloggers post a very nice to automate
updating your packages from R3.6.  I just used it to do my update from
R4.0 to R4.1 - it works perfectly.  I would include the script here, 
but since I don't have the exact reference I don't like posting someone
else's script without appropriate credit.  Do a search and you should
be able to find the entry.

Hans,

you seem to be using old library from 4.0 (see the 4.0 in the path).

Make sure you remove old packages and use a clean library for 4.1 since
you cannot mix packages from R 4.0.x and R 4.1.0. I would best
recommend removing (or re-naming) ~/Library/R before installation to
make sure you don't have incompatible old packages. Also don't forget
to re-start R.

(Marc, I can't parse your post, it makes no sense to me, there no

R-devel involved in any of this, so please post separately about
whatever is on your heart as that doesn't seem to be related).

Cheers,
Simon

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':

   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)?
