Cannot install mdbook using readme command #1126
Description
When I tried build for the first time, I cannot install mdbook.
When I ran cargo install mdbook --version ^0.2 --force, the following error was output.

Summary Failed to install mdbook, CONTRIBUTING.md, LICENSE-APACHE, LICENSE-MIT, README.md, book.toml, src (see error(s) above).
error: some crates failed to install
But when I ran cargo install mdbook --version 0.2 --force (remove ^), I could install mdbook.
Is this way is ok? If not, how should I install this?
