Can you post the stack trace? (Run it like env RUST_BACKTRACE=1 cargo run --release
)

However, when I try to build the book, I encounter the following error:

Did anybody else try to do the same?

Okay, damn, that's really unhelpful stack trace! The only thing of note here is 10: compile_trpl::main
– the rest is just the panicking machinery. Sadly, this is also code I've written 2.5 years ago and has thus not really anything like the current state of the art error reporting (that you get e.g. with error-chain or the failure crate).
Since it says "No such file or directory", I'd just go looking for File
stuff and add some logging. E.g., this helper here:
Could be changed to report some more info, something like this.
Fixed by #52
That is awesome.
Thank you. @abcdev
