错误：“ggplot2”的包或命名空间加载失败：包“ggplot2”是在 R 4.0.0 之前安装的：请重新安装执行停止

Question

I'm really stuck and need some help.

After installing R 4.0.2, I'm getting this error message on R visualizations in Power BI Desktop which were previously working

"Error: package or namespace load failed for 'ggplot2':
 package 'ggplot2' was installed before R 4.0.0: please re-install it.
 Execution halted"

I already tried to:

reinstall R 4.0.2

reinstall RStudio

reinstall ggplot2 

reinstall all packages

reinstall Power BI Desktop. My version is August-2020

Still it does not work.

Considerations:

My visualizations were working well before I installed R 4.0.2

My visualizations are working well on other PCs

When I run the code on RStudio I don't get any error

Any thoughts?

You probably need to go here: https://powerbi.microsoft.com/en-us/support/ , but some guesses:

When you did the reinstall, you didn't clean up the old one, so you now have a mix of old and new versions of things. If you can run R code, run

system.file(package="ggplot2")

That's where it is finding the bad version of ggplot2 . Get rid of it, and reinstall. If that's not enough, run

.libPaths()

in the broken copy of R. Completely eradicate every directory mentioned there, and reinstall R and all of your contributed packages. (I don't use Power BI, so this might also require you to wipe out some part of it: do so, and reinstall it.)

After all of this, run

packageDescription("ggplot2")

In the last line (or close to it) of what gets printed, you should see something like this:

Built: R 4.0.2; ; 2020-07-16 22:49:23 UTC; unix

If you see that it was built before 4.0.2, then either you missed deleting something, or you (or Microsoft) reinstalled some old version. Then it's probably time to contact that URL above.
