Having some issues helping a colleague at work install RStudio. She was getting the following error message whenever she opened up the programme and when trying to install new packages.
Error in yaml.load(readLines(con), error.label = error.label, ...) : object 'C_unserialize_from_yaml' not found Error in yaml.load(readLines(con), error.label = error.label, ...) : object 'C_unserialize_from_yaml' not found
We’ve tried uninstalling the
yaml package (which resulted in a different error message about the package not existing, as expected), reinstalling it (brought back the old message), installing older versions of it (same error message). Also reinstalled RStudio, both current and previous versions, but got the same error message.
R version is 3.4.3, RStudio is 1.1.423 for Windows and yaml version that was originally installed was 2.1.16. Not sure if it’s relevant, but we are on work laptops that require us to install new programmes (and in the case of R, packages) into
C:\Users\NAME\Desktop\My Software. Given uninstalling and reinstalling various versions of RStudio and the package hasn’t solved the problem, it feels like that might be the cause. But then we’ve never come across the issue before, so I’m a little stumped.
Any help greatly appreciated.
