Error: package or namespace load failed for ‘ROracle’


After upgrading R to 3.5.0 I am getting an issue with "ROracle" package. Trying to execute SQL query through R Studio and getting below error message:

Error: package or namespace load failed for ‘ROracle’:
package ‘ROracle’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version

I tried updating ROracle package but it didn't work.
Can someone please help me out?


Based on the CRAN check results for ROracle, it looks like there's an issue with installing the package in the release version of R (3.5.0).

It doesn't look like the package is on GitHub, and there's not a link for reporting issues/bugs, but I think this is an issue that will need the package maintainers to step in…
P.S. Does this work in R, but not in the RStudio IDE? If it's not an IDE-dependent issue, could you please move the question to the #general category (in this case)?


Hi Mara,

Thanks for your reply. I reverted back updated to 3.4.4 and it works fine now. Maybe the issue with package compatibility with the newer version of R (3.5.0). I will move the case to "General" category.


I assume that's the case. Hopefully a fix is in the works!
