Error: package or namespace load failed for 'treesnip' - r

Question

When trying to install the treesnip package from github using remotes::install_github("curso-r/treesnip"), I get the following error:
remotes::install_github("curso-r/treesnip")
Downloading GitHub repo curso-r/treesnip#HEAD

I works fine when running on another PC.
I also tried changing the library location to C:/Users/SAR.V-LOG/, but that didn't help either.
Further I tried to provide INSTALL_opts = "--no-test-load". When I do that the installation finished wihtout errors, but when I try to load the library using library(treesnip) I get the same error: The values passed to set_encoding() are missing arguments: 'allow_sparse_x'
Do you know what is causing this error and how I can fix it?

Answer 1

treesnip is fixed. It now depends on parsnip (>= 0.1.3.9000) https://github.com/curso-r/treesnip/commit/902a33d9f156c10da6dbe1bd9cccb65926077197

Answer 2

Try using parsnip 0.1.3 (not the development version in this case). It looks like 0.1.3.9000 has some breaking changes coming that will be handled in a new version of parsnip-adjacent packages.
The warning message indicates:
Please download and install Rtools 4.0 from https://cran.r-project.org/bin/windows/Rtools/.
You may need to upgrade your Rtools, which can be done here: https://cran.r-project.org/bin/windows/Rtools/
Let me know if this fixes your problem.
Also I have added a GitHub Issue Here: https://github.com/tidymodels/parsnip/issues/376
