engine bash not work on windows OS about knitr-examples

[kevinushey]

I've reproduced the issue there; it is indeed an RStudio issue and we'll try to dig in further!

Okay. This issue belongs to the RStudio IDE and R Markdown Notebooks, so support.rstudio.com may be a better place to report it. Thanks!

The error message looks weird to me. knitr does not write the bash code to a file before executing it. How exactly did you compile this document? I feel you might be using R Markdown Notebooks.

Yes, but then I tried md_document, html_codcument, word_document and ioslides_presentation, none of them worked. Below shows the minimal Rmd file to generate my error.

---
title: "process"
output: md_document
---
```{bash} 
echo hello world
echo 'a b c' | sed 's/ /\|/g'
```

bash: C:\Users\MyName\AppData\Local\Temp\RtmpmouNnD\chunk-code46b81ccd775f.: No such file or directory

And I can see nothing newly produced in the RtmpmouNnD directory.

You didn't actually answer my question: how exactly did you compile this document? The Knit button on the RStudio IDE toolbar? Command-line? The toolbar above the code chunk? I wouldn't expect the last approach to work.

[biociao]

Now I understand. The error occurred when I click any kind of 'run' button in the 'Run' menu on the RStudio IDE toolbar.

Command-line or type render(input="README.Rmd") in RStudio both work well.

@Scelta: do you see this same issue in the RStudio preview release?
