Building Solana from Source results in error: expected item, found `..` --> frozen-abi/macro/build.rs:1:1

Question

When running ./scripts/cargo-install-all.sh . from the instructions in the Solana docs (https://docs.solana.com/cli/install-solana-cli-tools#build-from-source) I am seeing

error: expected item, found '..'
 --> frozen-abi/macro/build.rs:1:1

  | ^^ expected item

error: expected item, found '..'

error: build failed

I have to build Solana from source because when I installed Solana through the command prompt from the Windows instructions in the docs, running solana-test-validator results in ERROR solana_perf] Incompatible CPU detected: missing AVX2 support. Please build from source on the target

I am on Windows 10 using WSL: Ubuntu-18.04.

Would switching to a new Macbook help?

Found the problem. I had to clone the repo instead of downloading the Source Code zip file. https://forums.solana.com/t/solana-test-validator-error-missing-avx2/3272/10
