[-]rustup should explain how to install the doc instead of silently failing[/-][+]rustup doc should deal with absent doc instead of silently failing[/+]on Jan 5, 2017 @toastedcornflakes ah thank you for this issue! I was trying to understand why
rustup doc --bookdoesn't seem to work.+1
It doesn't fail silently here, but it fails: When I do
rustup doc, I get the following error:Unable to run the command specified. The file or folder /home/r/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/share/doc/rust/html/index.html does not exist.It is not at all obvious to me how to even install the docs.
rustup help docdoesn't tell me. Seems like I will have to do some more googling...- added a commit that references this issue
on Nov 10, 2019 #2116 is what I had in mind when I raised this, thanks!
Thank you.
On a new install of rustup, running
rustup docfails silently if the documentation is not installed: the browser does not open, and there is no error message.Would it be OK to add an error message, or to automatically run
rustup component add rust-docs?This is tangentially related to #891 — if the doc is installed by default, this issue would be moot.
