running start.R asks for various package installations every time

[sreyam-sengupta]

Dear all,

Thanks for reading!

Error background and description:
When I try to run source("start.R"), either from R shell or from Rstudio IDE, it asks me to download and install a number of packages (screenshots attached). This happens every time. When I press Y(es), the packages are downloaded and installed. Previously, after this step, it displayed a menu containing various start scripts and their descriptions, i.e. things were running normally.

But now, I get the following error message:

Error: package or namespace load failed for ‘lucode2’ in library.dynam(lib, package, package.lib):
 DLL ‘data_table’ not found: maybe not installed for this architecture?

this, inspite of having downloaded and installed lucode2 multiple times from source, with all dependencies. I'm not sure what's going on, and any help would be appreciated.

System and version specifications:
OS: MS Windows 10 Pro
System architecture: x64
R version 4.3.2
renv 1.0.3
GAMS version 45
MAgPIE branch: https://github.com/jansteinhauser/magpie.git (builds on version 4.6.7)

Please let me know if there's any other relevant info I can provide. Thanks!

Seems like the bootstrapping process is not happening as planned. Only the first time when you start an R session in the magpie folder (this is crucial) your renv will be filled with all the packages you need, because the .Rprofile is run. After that you should never run into the requirement check again that asks you to install everything. So I'd suggest you clone magpie from scratch, and then start an R session in that folder. You should get the message "R package dependencies are not installed in this renv, installing now...". If you don't or errors/warnings come up feel free to post them here.

Thanks a lot, I'll try that!

I solved the issue: I had originally cloned the repo to a network drive (local to my institute, but not to my PC). That was the source of error. I deleted that repo and re-cloned a fresh instance to the C drive (local to my PC). Now everything works perfectly, thanks!
