Problem loading knitcitations package in R 3.6.3

[Banshee891]

I'm having trouble loading my knitcitations package for R markdown. It keeps giving me the following error message:

> library(knitcitations)
Error: package or namespace load failed for ‘knitcitations’ in loadNamespace(i, 
c(lib.loc, .libPaths()), versionCheck = vI[[i]]): there is no package called 
‘stringi’

I've tried to uninstall and reinstall knitcitations as well as use installl.packages("stringi", repos="http://cran.rstudio.com/", dependencies=TRUE), however neither of those seem to be working. Any help would be greatly appreciated.

installl.packages("stringi", repos="http://cran.rstudio.com/", dependencies=TRUE)

Can you post the complete output message you get when you run this command?

[Banshee891]

Yes, here it what it gives me:

It also mentions in the beginning warning that I don't have Rtools installed, which I made sure I did have.

warning that I don't have Rtools installed, which I made sure I did have.

What version of Rtools have you installed? It has to be compatible with your R version.

To solve this part, you just have to follow the instructions and delete that file.

[Banshee891]

The Rtools that I have installed is rtools40-x86_64 (this was on the installer I downloaded).

And then I found and deleted the indicated file described in the instructions you pointed out.

[andresrcs]

RTools40 is for R >= 4.0.0 since you are using R 3.6.3 you have to use Rtools35, you can download it from here

https://cran.r-project.org/bin/windows/Rtools/history.html

Or, you could update your R version

That worked!! Thank you so much! I was able to download the stringi package and load both that and knitcitations correctly. My document is also knitting properly now.

If your question's been answered (even by you!), would you mind choosing a solution? It helps other people see which questions still need help, or find solutions if they have similar problems. Here’s how to do it:

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …
