Can't load simr package


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.
