Failure when installing metacoder in RStudio in both windows and Ubuntu 20.04

Hi,

I got this error when installing metacoder in windows:

devtools::install_github("grunwaldlab/metacoder")
WARNING: Rtools is required to build R packages, but is not currently installed.

Please download and install Rtools 4.0 from https://cran.r-project.org/bin/windows/Rtools/.

Error: Failed to install 'metacoder' from GitHub:
Could not find tools necessary to compile a package
Call pkgbuild::check_build_tools(debug = TRUE) to diagnose the problem.

I also have an issue installing it in Ubuntu 20.04

Thanks in advance for any provided support!

It looks like from the error that you need to install Rtools. Its not uncommon for some software to need to be installed by the user outside of R. If a package does not install, that is usually the reason and the thing you need to install can usually be found by reading and internet searching error messages.

Can you paste the result of SessionInfo()?

It was version incompatibility. I updated R version and installed metacoder in Ubuntu now. I will check for windows and see.
Much thanks for your support!
