Can't load simr package

Hi,

I'm trying to get the package simr running. I installed lmer4 and car and simr. When I try to load simr I get the error:

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

I have a Mac using macOS Catalina.

You are missing one more package dependency, you have to install it first.

install.packages("stringi")

Can you post the complete message you get? We need more information to help you.
