MRAN issues #35

Open bykovam opened 1 year ago

bykovam commented 1 year ago

I'm trying to install multiple version of Seurat for troubleshooting reasons, and when I tried, this error emerged:

options(repos="https://CRAN.R-project.org") versions::install.versions('Seurat', version = '4.3.0', lib = new_lib_loc) Error in download.file(url, file, quiet = TRUE) : cannot open URL 'https://mran.revolutionanalytics.com/snapshot'

I tried to go to that URL, and I see an "Error 403 - Forbidden The web app you have attempted to reach has blocked your access."

Is there a way to go around the issue, perhaps by querying CRAN instead of MRAN?

@bykovam MRAN stopped capturing updates a while ago and was completely turned off on July 1, 2023. I would recommend that you use remotes::install_version as a work-around for Seurat. The versions package would need a bit more work to work again (I'm logging the issue). Please see https://satijalab.org/seurat/articles/install.html#install-previous-versions-of-seurat
