error[E0424] building substrate template for first tutorial

[01willtx]

I'm trying to complete the 1st tutorial from https://www.substrate.io/tutorials/create-your-first-substrate-chain/v2.0.0-rc2

The following error from running the command cargo build --release resulted

  error[E0424]: expected value, found module `self`

I guess this can help #44

Thank you, @herou. I will consider updating the instructions for Windows to mention this since it seems to be a common problem.

@danforbes This isn't solely a windows problem, I'm on MacOS Catalina 10.15.5. I'll try the answer provided in issue #44 and report back. Thanks @herou !

Also, this: rustup target add wasm32-unknown-unknown --toolchain nightly-2020-05-15 not a big deal but if I were to come across a package/library with "unknown" in it's naming I would not use it and it would turn me off to the library. I expect anything related to blockchain tech to project the warm and fuzzies of the highest security. It's just a name, but seems sloppy and if I didn't come across it via the tutorial I wouldn't trust it. :-)

[danforbes]

The unknown target is not "a Substrate thing", it is "a Rust thing" that's related to compiling to Wasm, I believe. Ref: rust-lang/rust#45905.

Thanks @danforbes! That worked, I was able to compile successfully.
