尝试使用 install_github [R] 安装小插图时无法构建包

Question

默认情况下，当一个人在 R 中使用 devtools 包中的 install_github 函数时，安装包的小插图不会构建。我已经看到这个带有答案的问题，它显示了如果有人愿意的话如何构建小插图 Building R package from github: how to disable building vignettes?.

我用 such vignettes 写了一个包，但是我收到了一个错误，直接从 github 安装是这样的：

当我从本地源代码构建包时，没有任何错误。谁能知道这是什么原因造成的？

Answer 1

我需要添加

.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)
}

此函数到 R/ 目录中的 zzz.R 文件和 knitr 包到 DESCRIPTION 文件中的依赖项。
