Can't install via cargo install; Cargo ignores clap version #42
Description
This is a weird one. I can clone the project and build it locally just fine, but if I try and install it from crates.io with cargo install rust-script (or from a local checkout with cargo install --path .) I get a bunch of errors like the following:
...
Compiling clap v3.0.0-rc.0
...
Compiling rust-script v0.18.0
error[E0599]: no method named `about` found for struct `Arg` in the current scope

...Looks like Cargo.toml specifies clap-3.0.0-beta.5 which indeed has the Arg::about method, but as you can see above cargo install tries to use clap-3.0.0-rc.0 which does not have Arg::about. Why would Cargo be doing this? Is there a workaround?
