HI, I am new to rust and was reading official rust "book", i installed rust via following cmd: curl --proto '=https' --tlsv1.3 https://sh.rustup.rs -sSf | sh while the official book mentions we can open rust docs locally offline after we have installed rust, by the following command rustup doc but when I run this command, it gives me error: couldn't open browser: IO error: No such file or directory (os error 2). How can I solve this? I even tried with sudo user but that didint worked either.
You might have a BROWSER environment variable set to some command that doesn’t exist? If you have, unsetting it might help. If the BROWSER environment variable is not the problem, it can still be the solution: try setting it to some web-browser, e.g. see if it works if invoked as
env -u BROWSER rustup doc
or
BROWSER="google-chrome" rustup doc
If that solves the issue, consider changing the environment variable permanently (there’s lots of resources out there how to do that, in case you are not familiar).
