Dear Knime community, can you tell me, since when R scripting nodes are relying on package Rserve? Has something changed in the shorterm or haven’t I just been aware R snippets were allwas using Rserve? Moreover, I am experiencing warnings stating that all Rserve versions below or equal to 1.8.6 aren’t optimal (in other words buggy) for deploying R Snippet Nodes. That happened to me with several KNIME versions (3.5x and 3.6.1) Unfortunately there is no newer version of Rserve than 1.8-5, unless I missed on something here. I’d be happy, if somebody could elaborate briefly on this topic or share potential fixes. Thanks in advance,datastic ---

There is a Version 1.8.6 and it is recommended to use it. But you would have to install it like this: > [@R Problems on macOS (high sierra) since R version 3.5](https://forum.knime.com/t/r-problems-on-macos-high-sierra-since-r-version-3-5/10935/11): > > This issue was fixed in R 3.5.1 and Rserve 1.8-6. To get that version of Rserve, you will need to install it via: install.packages('Rserve',,"http://rforge.net/",type="source") ---

Unfortunately, R is throwing errors, when trying to build Rserve from source. I probably don’t have all the prerequisites for the compilation. Is there another way to get a compiled version of Rserve 1.8.6? ---

You may also install an earlier R version instead, e.g. 3.4.3, if you don’t depend on changes in the R 3.5 versions. > Is there another way to get a compiled version of Rserve 1.8.6? You could try omitting the `type="source"` parameter, it _may_ work. If it fails, it will fall back to asking you whether you want to be building from source instead, though. ---

If you run MacOS you might have to install additional software in order to compile packages [https://cran.r-project.org/bin/macosx/tools/](https://cran.r-project.org/bin/macosx/tools/) ---
