Hello,
I am trying to create a virtual environment in the zzz.r file of my
package, and my package is currently passing on Windows and failing on
Debian with 1 ERROR.
This is the ERROR:
* installing *source* package ‘PytrendsLongitudinalR’ ...
** using staged installation
** R
** inst
** byte-compile and prepare package for lazy loading
** help
*** installing help indices
** building package indices
** installing vignettes
** testing if installed package can be loaded from temporary location
Using Python: /usr/bin/python3.12
Creating virtual environment '/home/hornik/.virtualenvs/pytrends-in-r-new' ...
+ /usr/bin/python3.12 -m venv /home/hornik/.virtualenvs/pytrends-in-r-new
The virtual environment was not created successfully because ensurepip is not
available. On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.
apt install python3.12-venv
You may need to use sudo with that command. After installing the python3-venv
package, recreate your virtual environment.
Failing command: /home/hornik/.virtualenvs/pytrends-in-r-new/bin/python3.12
FAILED
Error: package or namespace load failed for ‘PytrendsLongitudinalR’:

* removing
‘/srv/hornik/tmp/CRAN_pretest/PytrendsLongitudinalR.Rcheck/PytrendsLongitudinalR’
and this is the onLoad function of my zzz.r file:
.onLoad <- function(libname, pkgname) {
# Define paths
venv_path <- file.path(Sys.getenv("HOME"), ".virtualenvs",
"pytrends-in-r-new")
python_path <- file.path(venv_path, "bin", "python")
# Ensure 'virtualenv' is installed
if (!reticulate::py_module_available("virtualenv")) {
reticulate::py_install("virtualenv")
}
# Check if the virtual environment exists
if (!reticulate::virtualenv_exists(venv_path)) {
# If it doesn't exist, attempt to create it
tryCatch({
reticulate::virtualenv_create(envname = venv_path, python =
python_path, force = TRUE, module =
getOption("reticulate.virtualenv.module"))
}, error = function(e) {
# Fallback: install Python and create the virtual environment
reticulate::virtualenv_create(envname = venv_path, force = TRUE,
module = getOption("reticulate.virtualenv.module"))
})
}
# Use the virtual environment for reticulate operations
reticulate::use_virtualenv(venv_path, required = TRUE)
# Install packages if not already installed
packages_to_install <- c("pandas", "requests", "pytrends", "rich")
for (package in packages_to_install) {
if (!reticulate::py_module_available(package)) {
reticulate::py_install(package, envname = "pytrends-in-r-new")
}
}
TrendReq <<- reticulate::import("pytrends.request", delay_load =
TRUE)$TrendReq
ResponseError <<- reticulate::import("pytrends.exceptions",
delay_load = TRUE)$ResponseError
pd <<- reticulate::import("pandas", delay_load = TRUE)
os <<- reticulate::import("os", delay_load = TRUE)
glob <<- reticulate::import("glob", delay_load = TRUE)
json <<- reticulate::import("json", delay_load = TRUE)

TRUE)$RichHandler
math <<- reticulate::import("math", delay_load = TRUE)
platform <<- reticulate::import("platform", delay_load = TRUE)
# Configure logging
configure_logging()
}
How do I ensure that the virtual environment is created properly on
Debian systems? I tried the instructions in the error message but
still got the error.
Thank you in advance for your help!
Best,
