如何在Ubuntu 18.04虚拟机的Hugo站点中不依赖blogdown和RStudio使用.Rmd文件？

Got it, here's a straightforward, Linux-native workflow to integrate .Rmd files into your Hugo blog without relying on RStudio or the blogdown package—perfect for your Ubuntu 18.04 + VirtualBox setup:

核心思路 #

Instead of letting blogdown handle the pipeline, we'll directly use R's rmarkdown package to convert .Rmd files into Hugo-compatible Markdown (with proper front matter), then let Hugo do what it does best. This keeps the process lightweight and fully under your control.

具体配置步骤 #

1. 先搞定R和rmarkdown依赖 #

First, make sure your Ubuntu VM has R and the rmarkdown package installed:

• Install R via apt:

  sudo apt-get update && sudo apt-get install r-base
  

• Install the rmarkdown package (you can do this in the R console or via terminal):

  sudo R -e "install.packages('rmarkdown', dependencies = TRUE)"
  

2. 给你的.Rmd文件加Hugo Front Matter #

Every .Rmd file needs Hugo's front matter at the top (wrapped in ---) so Hugo recognizes it as a blog post. Here's an example template:

---
title: "My R-Powered Blog Post"
date: 2024-05-20T14:30:00+02:00
draft: false
categories: ["Data Analysis"]
tags: ["R", "Visualization"]
---

Below this, write your R code chunks and markdown content like you normally would:

```{r mtcars-summary, echo=TRUE}
# Example R code
summary(mtcars[, c("mpg", "hp")])

This is some explanatory text about the summary output above. You can mix regular markdown and R code chunks freely.

### 3. 自动化转换脚本（推荐）
Manually converting each .Rmd file gets tedious, so let's make a script to batch-convert them.

#### Option 1: R Script
Create a file named `convert_rmd.R` in your Hugo site root:
```r
library(rmarkdown)

# Set the path to your Hugo posts directory
posts_dir <- "./content/posts"

# Find all .Rmd files in the directory
rmd_files <- list.files(posts_dir, pattern = "\\.Rmd$", full.names = TRUE)

# Convert each .Rmd to Hugo-ready Markdown
for (file in rmd_files) {
  output_path <- sub("\\.Rmd$", ".md", file)
  render(
    input = file,
    output_format = "markdown",
    output_file = output_path,
    params = list(toc = FALSE) # Adjust params as needed
  )
}

Run it from the terminal:

Rscript convert_rmd.R

Option 2: Bash Script

If you prefer a shell-based approach, create convert_rmd.sh:

#!/bin/bash

# Target directory (adjust if your posts are elsewhere)
POSTS_DIR="./content/posts"

for rmd_file in "$POSTS_DIR"/*.Rmd; do
  # Replace .Rmd with .md for output
  md_file="${rmd_file%.Rmd}.md"
  # Call rmarkdown to convert
  Rscript -e "rmarkdown::render('$rmd_file', output_format = 'markdown', output_file = '$md_file')"
done

Make it executable and run:

chmod +x convert_rmd.sh
./convert_rmd.sh

4. 生成/预览你的Hugo站点 #

Once the .md files are generated, use Hugo's standard commands:

• Preview locally:

  hugo server -D
  

• Build the static site for deployment:

  hugo
  

5. 可选：实时自动转换 #

For a smoother workflow, use entr (a lightweight file-watch tool) to auto-convert .Rmd files when you save them:

• Install entr first:

  sudo apt-get install entr
  

• Run this command in your Hugo root:

  ls ./content/posts/*.Rmd | entr ./convert_rmd.sh
  

Now every time you save changes to an .Rmd file, it will auto-convert to Markdown, and Hugo's dev server will refresh the page instantly.

No need to stress about apologizing to Yihui—sometimes a direct, no-frills workflow is exactly what fits your setup. This method keeps you in full control without the overhead of RStudio or blogdown.
