嘗試使用install_github [R]安裝暈影時無法構建程序包

Question

默認情況下，如果在R中使用devtools包中的install_github函數，則不會構建已安裝包的插圖。 我已經看到了這個問題，答案顯示了如果想要從github構建R包中如何構建小插圖：如何禁用構建小插圖？ 。

我寫了一個帶有這樣的小插圖的包，但我收到一個錯誤，直接從github安裝如下：

當我從源本地構建包時沒有錯誤。 任何人都可以知道這可能是什么原因？

我需要補充一下

.onLoad <- function(libname, pkgname) {
    vig_list = tools::vignetteEngine(package = 'knitr')
    vweave <- vig_list[['knitr::knitr']][c('weave')][[1]]
    vtangle <- vig_list[['knitr::knitr']][c('tangle')][[1]]
    tools::vignetteEngine(pkgname, weave = vweave, tangle = vtangle,
                          pattern = "[.]Rmd$", package = pkgname)
    #register_vignette_engines(pkgname)
}

這個函數用於R/目錄中的zzz.R文件和針對DESCRIPTION文件中的依賴項的knitr包。
