I’m on the introduction part of the book The Rust Programming Language. More specifically, I’m trying to install rustup. Since my OS is the 64-bit Windows 11, I had to go to the rustup website for installation. Instead of using the download link, I opted to use the Linux on Windows option (since I already have Ubuntu 22.04.3 running as WSL).
I ran the command rustup doc on Powershell (running as admin). Instead of the doc being open, I got this message:
rustup doc
Opening docs in your browser
error: couldn’t open browser: error spawning command(s) ‘wslview, xdg-open’: No such file or directory (os error 2)
Can someone explain to me why I’m getting this error? How can I solve this?

Ive googled the entire message I shared, but since I’m new to using any CLI or terminal simulator as my primary way of navigating my computer, I found the explanations a little hard to understand. I want to use this to understand better how OS and terminals work. If anyone can explain to me what and why exactly caused this error, I could figure all this out on my own in the future. Any explanation would be highly appreciated.
