dsBaseClient installation fails on MacOS 10.14.6 (Mojave)


On my desktop I am still using MacOS 10.14.6 (Mojave), and when trying to install the dsBaseClient-package in R/RStudio, as it was part of the February “DataSHIELD newcomvers’ workshop”, I get the error message that the corresponding URL ca not be found:

> install.packages('dsBaseClient', repos=c(getOption('repos'), 'http://cran.datashield.org'), dependencies=TRUE)

Warning in install.packages :
  unable to access index for repository http://cran.datashield.org/src/contrib:
  cannot open URL 'http://cran.datashield.org/src/contrib/PACKAGES'
Warning in install.packages :
  package ‘dsBaseClient’ is not available for this version of R

A version of this package for your version of R might be available elsewhere,

Warning in install.packages :

I am aware that I am here a bit on the old school conservative path, especially as the official support of Mojave has finally ended last year.

Though, the error message does not hint on any specific MacOS version, I can not verify, if it works with a more up to date MacOS version, because I have not access to a Mac running High Sierra, Big Sur or Monterey.

NB: The installation of the “dsBaseClient” R-package worked on a Windows10-machine.

Best regards,



There is no macosx specific build. What if you try to install directly from the source?

remotes::install_github("datashield/dsBaseClient", ref="6.1.1")


Hi Yannick,

I see. That was my thought,

I would have expected more MacOS users (amongst those using the DataShield course example), so I was surprised being the only one running into that problem at the beginning.

Thanks, that worked.

Best regards,
