Whole error:

error: cannot find macro `thread_local` in this scope

     = note: `thread_local` is in scope, but it is an attribute: `#[thread_local]`
     = note: this error originates in the macro `$crate::thread_local_impl` which comes from the expansion of the macro `environmental::environmental` (in Nightly builds, run with -Z macro-backtrace for more info)

I tried all the things like installing wasm32-unknown-unknown.I also tried updating cargo with cargo update, before used cargo clean and used cargo build --release. also tried to pull if there were problem with my subsrate current node. Can anyone please help me with this.

I've fixed it by adding my new pallet' STD feature. So if you have your Cargo.toml like

[dependencies]
pallet-dummy = { git = "https://github.com/xxx", default-features = false }

Then simply add

[features]
default = ["std"]
std = [
    "pallet-dummy/std",
]
