Description of bug

When run cargo build --release to substrate-node-template, I met this problem like "Rust WASM toolchain not installed, please install it!", although I have installed it. The details are as follows.

Steps to reproduce

Hello everyone:
When I used commend cargo build --release to substrate-node-template, I get something wrong like this:

error: failed to run custom build command for node-template-runtime v4.0.0-dev (/home/briza/Desktop/substrate/substrate-node-template_ok/runtime)

Caused by:
process didn't exit successfully: /home/briza/Desktop/substrate/substrate-node-template_ok/target/release/build/node-template-runtime-219434d0a12d33e9/build-script-build (exit status: 1)
--- stderr
Rust WASM toolchain not installed, please install it!

Further error information:

error: expected table for configuration key registry, but found string in /home/briza/.cargo/config

I checked my toolchain, and installed: rustup toolchain install nightly-2022-10-20-x86_64-unknown-linux-gnu, but stiil didn't work.

rustup show and rustup nightly show below:

Besides, I followed this "https://docs.substrate.io/install/linux/" to reinstall, but still didn't work
what should I do to solve this problem?
thank you all first!

Have you added the WASM target to your toolchain? Something like this rustup target add wasm32-unknown-unknown --toolchain nightly

https://docs.substrate.io/install/linux/ This doc might help you out.

Have the same issue with the following toolchain:

nightly-x86_64-unknown-linux-gnu

installed targets for active toolchain

wasm32-unknown-unknown

@paritytech/docs-audit we need the installation instructions updated. Since 1.69.0 and latest master people need to have the wasm32-unknown-unknown target installed for the stable compiler.
