[SkymanOne]

cargo-contract v3.0.1 is incompatible with rusc 1.68 or newer. You should use cargo-contract v3.2.0 which is a successor of 3.0.1 and addresses the issue.

[ascjones]

Installing with --locked should fix this:

cargo install cargo-contract --version 3.0.1 --force --locked

However as @SkymanOne points out, it won't work for building contracts with the 1.70 toolchain, so we recommend installing 3.2.0 instead.
