使用render编译Rmarkdown文档

当我直接在RStudioIDE中编织Rmarkdown模板时，它会准确地创建所需的PDF。但是，当我尝试使用rmarkdown:：render（）编织文档时，我遇到了一个无法理解的错误。我已经安装了Rmarkdown和MikTex的最新版本。详情如下:

下面是我使用的Rmarkdown模板。谢谢你能给我的帮助

title: "Test"
output: pdf_document

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

## R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.

When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

```{r cars}
summary(cars)
```

## Including Plots

You can also embed plots, for example:

```{r pressure, echo=FALSE}
plot(pressure)
```

Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.

windows上的“状态127”通常意味着在路径中找不到可执行文件。

Sys.which（“pdflatex”）

给你什么？（如果

”

，那么问题是

MiKTeX

或windows-

TeXLive

不在路径中。RStudio在调用

pandoc

和friends时可能会自行修复此问题。）rEvans-我得到的Sys.which（“pdflatex”）返回“”是正确的。但当我运行Sys.getenv（“PATH”）时，我会在正确的路径中看到MikTex（“C:\\Users\\sshewfelt.INGENUITY\\AppData\\Local\\Programs\\MikTex 2.9\\MikTex\\bin\\x64\”）。有什么建议吗？如果你不介意的话，卸载MiKTeX，然后测试TinyTeX：（你需要重新启动R/RStudio），这样做效果很好。非常感谢易慧！虽然我不知道为什么MiKTeX没有为你工作，但我很高兴TinyTeX还是工作了。
