Blocking waiting for a file lock on the registry index after building parity from source

Question

I followed the readme instructions for building Parity from source and then I execute this command: cargo build --release and then: ~/.cargo/bin/cargo build --release .. as instructed; both of which cause me to receive the following message while the prompt hangs: Blocking waiting for file lock on the registry index I'm on a Mac.

Answer 1

I had the same issue and got around it with rm -rf ~/.cargo/registry/index/*.
