Trouble with creating first Substrate chain

When I try to compile the Node Template I get a series of errors.
error: failed to run custom build command for node-template-runtime v2.0.0 (/Users/Modulus3D/VSCode Projects/substrate-node-template/runtime)

Caused by: process didn't exit successfully: /Users/Modulus3D/VSCode Projects/substrate-node-template/target/release/build/node-template-runtime-cae9ad6029c9f681/build-script-build (exit code: 1) --- stdout Executing build command: "rustup" "run" "nightly" "cargo" "rustc" "--target=wasm32-unknown-unknown" "--manifest-path=/Users/Modulus3D/VSCode Projects/substrate-node-template/target/release/wbuild/node-template-runtime/Cargo.toml" "--color=always" "--release"

and also:

error: aborting due to 3 previous errors

For more information about this error, try rustc --explain E0282. error: could not compile sp-arithmetic

To learn more, run the command again with --verbose. warning: build failed, waiting for other jobs to finish... error: build failed warning: build failed, waiting for other jobs to finish... error: build failed

Any suggestions on how to resolve these errors??

Fresh project always facing the efferent nightly versions issue. If you running the substrate version 2.0.0 you can solve it with bellow command:

rustup install nightly-2020-07-02
rustup override set nightly-2020-07-02
rustup target add wasm32-unknown-unknown --toolchain nightly-2020-07-02

then try to re build again!

Look like you need to downgrade you nightly version.

You can do so by running the following sequence of commands:

rustup install nightly-2020-10-06
rustup target add wasm32-unknown-unknown --toolchain nightly-2020-10-06
export WASM_BUILD_TOOLCHAIN=nightly-2020-10-06

You can learn more about how nightly is used with substrate here: https://substrate.dev/docs/en/knowledgebase/getting-started/#rust-nightly-toolchain
