r - 无法在 bookdown 中插入图

Question

我正在使用 bookdown 为 R 生成注释。显示错误的最小 bookdown 示例:

https://github.com/DavisBrian/bookdown_error

一切都很好，直到我尝试添加一个情节 (dataviz.Rmd)。在构建这本书时，我收到以下错误:

! LaTeX Error: File `dataviz_files/figure-latex/plotxyx-1' not found.

Error: Failed to compile rclassnotes.tex. See rclassnotes.log for more info.
In addition: Warning message:
In parse_packages(logfile, quiet = c(TRUE, FALSE, FALSE)) :
  Failed to find a package that contains dataviz_files/figure-latex/plotxyx-1
Execution halted

Exited with status 1.

我已经运行了这个:

关于从这里去哪里的任何想法？

编辑:

它看起来非常类似于:
https://github.com/rstudio/bookdown-demo/issues/3
和
https://github.com/rstudio/bookdown/issues/342

注意我在 Windows 和 Mac OSX 上都有这个问题。我不认为这是其中一个组件的简单软件安装错误。

这些文件似乎是在 _bookdown_files/dataviz_files/figure-latex/和临时在 _dataviz_files/figure-latex/中创建的

问题是由于您将图形设备设置为 svg在 _common.R :https://github.com/DavisBrian/bookdown_error/blob/9f4078a/_common.R#L13

knitr::opts_chunk$set(
  comment = "#>",
  collapse = TRUE,
  cache = FALSE,
  out.width = "70%",
  fig.align = 'center',
  fig.width = 6,
  fig.asp = 0.618,  # 1 / phi
  fig.show = "hold",
  dev = "svg"
)

LaTeX 本身不支持 SVG 图像(至少目前是这样)。您必须使用特殊的 LaTeX 包，或者使用 LaTeX 可以识别的图像格式，例如 pdf或 png .
