'Rust nightly not installed, please install it

I was able to build and run substrate-node-template from the instructions from the cloned repo, following the instructions at https://substrate.dev/docs/en/tutorials/create-your-first-substrate-chain/

However when I try to do the follow on tutorial of adding the nicks pallet I get the following error. <Rust nightly not installed, please install it!>.

This is right after I run the command -

WASM_BUILD_TOOLCHAIN=nightly-2020-10-05 cargo build --release

I tried running the command -

WASM_BUILD_TOOLCHAIN=nightly-2021-02-12 cargo build --release

I get the same error.

Here is what I currently have -

$ rustup update

info: syncing channel updates for 'stable-x86_64-unknown-linux-gnu'

info: syncing channel updates for 'nightly-x86_64-unknown-linux-gnu'

info: checking for self-updates

stable-x86_64-unknown-linux-gnu unchanged - rustc 1.50.0 (cb75ad5db 2021-02-10)

nightly-x86_64-unknown-linux-gnu unchanged - rustc 1.52.0-nightly (e9920ef77 2021-02-11)

info: cleaning up downloads & tmp directories

Previously, I had built the cloned repo and everything worked fine.

Any help resolving this is appreciated.

Solution 1:[1]

Running only cargo run --release -- --dev --tmp without WASM_BUILD_TOOLCHAIN=nightly-2020-10-05 did the trick for me!

Solution 2:[2]

I had the same problem but i fixed it by updating rust and target "wasm" to nightly build

rustup update
rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly
