尝试使用install_github安装小插图时无法构建软件包[R] [英] Fail to build package when trying to install vignettes with install_github [R]

问题描述

默认情况下，在R中使用 devtools 软件包中的 install_github 函数时，已安装软件包的插图不建立。我已经看过这个问题，并给出了答案，该答案显示了如果有人希望
从github构建R包：如何禁用构建小插图？。

By default when one is using install_github function from devtools package in R the vignettes of the installed package are not build. I've seen this questio with an answer which shows how to build vignettes if one desires to Building R package from github: how to disable building vignettes?.

我用这样的小插曲，但我收到一个错误，直接从github安装是这样的：

I wrote a package with such vignettes and but I recieve an error what installing directly from github like this:

当我从本地本地构建软件包时，没有错误。谁能知道这是什么原因吗？

When I build package from source locally there are no errors. Can anyone know what can be a cause of this?

推荐答案

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)
}

此函数为 zzz.R 文件放在 R / 目录和 knitr 包中，以 DESCRIPTION中的依赖项文件。

this function to zzz.R file in R/ directory and knitr package to Dependencies in DESCRIPTION file.
