googler() with default arguments fails, but otherwise works

[leungi]

Reprex below.

I tried looking at source code, but can't find where the default arguments are set.

Sys.setenv("RETICULATE_PYTHON" = "C:\\Users\\leungi\\AppData\\Local\\Continuum\\anaconda3\\python.exe")
reticulate::py_config()

@leungi: would you be willing to re-install and try that code again? I made a number of changes, so although I cannot pinpoint exactly what caused this problem, I do think it has been resolved–I've done fairly extensive testing on Macs and Ubuntu Linux. But I'll wait to close this issue until I get confirmation from someone else.

Just installed latest; new error message 😅

Almost like users need to specify at minimum 2 arguments to work.
