I tried adding curl to the package manifest and it worked.
Thanks!

Dear Guix,
I'm stuck and could use some advice. I have R scripts which use the
httr2 R package (r-httr2) to make HTTP calls. These scripts do not run
out of the box inside a guix environment created by guix shell because
R makes the wrong assumption by default about where the web
certificates are. After reading the mailing list and the info manual,
I found a kludge workaround where I can define CURL_CA_BUNDLE
environment variable inside of R relying on GUIX_ENVIRONMENT. Now I'm
looking for a less tedious and more automated way of setting that
environment variable. I would prefer to have a single shell script
which sets up my guix environment setting that environment variable.
Right now, I have a list of commands which works.
$
CUSTOM_EMACS=$HOME/path/to/custom-configuration-with-necessary-R-packages
$ cd $CUSTOM_EMACS
$ guix shell -m manifest.scm # interactively the next two lines run
inside of this shell
$ export
CURL_CA_BUNDLE="$GUIX_ENVIRONMENT/etc/ssl/certs/ca-certificates.crt"
$ emacs --init-directory="$CUSTOM_EMACS"
Since the guix shell command takes control of the process, the last
two lines cannot be run in a script. What is an intuitive way to make
the shell do the same thing as I would do interactively? I'm guessing
there are some shell scripting concepts I am overlooking. However, I
am hoping this sort of issue is so common that there is a solution
which is also intuitive.
Thanks,
Kyle
Common way to solve this is to simply add the curl package into your
shell or manifest.
I would suggest to look at search-paths in the manual and how they are
used by the curl package definition if you are interested in the
details.
