Build error

[bo-hub]

Hi, thanks for the wonderful work.
I cloned the repo and try to built it. But I have touble to build it right. I faced the below error.

$ cargo build --release
error: failed to parse manifest at `/home/bob/code/crypto/pointproofs/Cargo.toml`

Caused by:
  failed to parse the version requirement `` for dependency `rand_core`

Caused by:
  unexpected end of input while parsing major version number

Could you take a look? Thanks in advance.

Change your cargo.toml like this.

cargo build --release

Could you take a look? Thanks in advance.
