an error shows everytime

since I reinstall my R because of the version is high(3.5,what my packages depended is 3.4), whatever I typed, it always shows error on the console. The error message is below. (The first appearance of this error was happened why I install lightgbm package.)

Error in UseMethod("conditionCall") :
no applicable method for 'conditionCall' applied to an object of class "character"

Anyone could give some hints about this error, I don't know how to solve it. Thank you!

I think we are missing some information on the problems you encounter.

Could you please turn this into a self-contained reprex (short for reproducible example)? It will help us help you if we can be sure we're all working with/looking at the same stuff.


If you've never heard of a reprex before, you might want to start by reading the help page. The reprex dos and don'ts are also useful.

What to do if you run into clipboard problems

If you run into problems with access to your clipboard, you can specify an outfile for the reprex, and then copy and paste the contents into the forum.

reprex::reprex(input = "fruits_stringdist.R", outfile = "")

For pointers specific to the community site, check out the reprex FAQ, linked to below.
