restarting interrupted promise evaluation

The complete error is:

> Error: cannot open file '/home/rstudio/book/book_cache/html/individual-asset-returns_40186e1f2d45679c0c1f9edda1e1e4d2.rdb': No such file or directory
In addition: Warning message:

I have knitr::cache set to TRUE.

I get this message after running preview_chapter("02-Averages.Rmd"). This is the only chapter I have. This message only shows after I've run the preview_chapter command. Every time I save an update ot the file, the message regenerates. There is no indication of any background running. If I let it continue too long it freezes Rstudio and I must restart the server. Then I get:

Error saving session (search_path): R code execution error
WARNING: Forcing suspend of process in spite of all session data not being fully saved.

The book_cache directory is created when the preview_chapter command is running but then disappears.

If I turn knitr::cache off, I do not get the error.

I'm running RStudio 0.99.893. Here is my sesssionInfo output:

I have no idea what this means, and you didn't provide a reproducible example, so there is nothing I can do about it. Sorry.

Since you are using RStudio, there is no need to call preview_chapter() by hand. The latest preview version of RStudio does this automatically for you when you click the Knit button: https://bookdown.org/yihui/bookdown/rstudio-ide.html

I noticed that he's not running the Preview release of RStudio. See the
bookdown getting started docs, it asks you to install the preview release:
