cannot quit radian

[isezen]

Hello, I can not quit radian because of the error below with Python 3.8 + radian 0.5.4.

r$> quit()
Error in .External2(C_savehistory, file) : no history available to save

r$> quit("no")
Error in .External2(C_savehistory, file) : no history available to save

r$> quit("yes")
Error in .External2(C_savehistory, file) : no history available to save

I cannot reproduce it but ctrl+d should at least work.

I'm sorry for the inconvenience. Whole the problem was savehistory command in my custom Rprofile.site file. It had the following code and command did not let the session to quit. OS is macOS.

.Last <- function() {
  if(interactive()) {
    hist_file <- Sys.getenv("R_HISTFILE")
    if (hist_file == "") hist_file <- "~/.Rhistory"
    savehistory(hist_file)
  }
}

By the help of issue: #98

    hist_file <- Sys.getenv("R_HISTFILE")
    if (hist_file == "") hist_file <- "~/.Rhistory"
    if (!nzchar(Sys.getenv("RADIAN_VERSION"))) savehistory(hist_file)
