Installing DESeq2 fails ; R can't find basic commands like 'rm' and 'mv'

So this might not be a Bioconductor question per se, but the error revealed itself when trying to install a Bioconductor package.

When trying to install DESeq2, I am failing because the dependency 'SummarizedExperiment' will not install. The console error messages seem to indicate shell errors where basic commands such as 'rm' and 'mv' are not being found.

When I check R's PATH using Sys.getenv() , the PATH looks normal and has the place where these commands are.

I have a sneaking suspicion that Apple did this to me. I updated my OS from Mojave to Catalina, and ever since whenever I open a Terminal window I have a message saying:

The default interactive shell is now zsh. To update your account to use zsh, please runchsh -s /bin/zsh. For more details, please visit

Behind the scenes when R is trying to do my install, is it falling into a shell that doesn't even know where rm and mv are? If so, any ideas on how to fix this?

R version 4.0.0, Bioconductor version 3.11. Full console information below with sessionInfo() at bottom.

I don't have a mac, but this forum post says you might need xcode?

Try googling around with your specific errors like:

sh: rm: command not found

Thanks. I had full Xcode installed. I also installed xcode-select , per the post you linked to, then rebooted. Alas, did not fix it.

The googling mostly leads to people who have done something silly like

sudo /bin/rm /bin/rm

or messed up their path with a strange .bash_profile, which wasn't me! Normal shell commands still work on my device. It's just the install process from R that has issues.

It does indeed seem strange. I'd try to reproduce this in a simpler context, e.g.,

instdir <- tempfile(); dir.create(instdir)
final_instdir <- tempfile()
system(paste("mv -f", shQuote(instdir), shQuote(final_instdir)))

XCode should not been needed for binary package installation.

The tests you suggested all work fine in my R console. But the installation attempt still gives same errors for 'SummarizedExperiment' attempted installation.

face <- palm

Turns out I had a bad line in my ~/.Renviron file that nuked the PATH. Fixing that solved my issue.

It was a bit confusing because, when Sys.getenv() was run from within an RStudio session, the reported PATH was fine. It was only when R was invoked from my terminal that I could see the PATH was not set correctly. It must be that during package installation the ~/.Renviron file was invoked.

Anyway, thanks for the suggestions.
