Cargo update 时报 Patch bellperson v0.12.3 (/lotus/bellperson) was not used in the crate graph.

执行cargo update时报如下警告：

    Updating crates.io index
warning: Patch `bellperson v0.12.3 (/lotus/bellperson)` was not used in the crate graph.
Check that the patched package version and available features are compatible
with the dependency requirements. If the patch has a different version from
what is locked in the Cargo.lock file, run `cargo update` to use the new
version. This may also occur with an optional dependency that is not enabled.

是不是安装失败？
