Substrate error - consider giving `accuracy` a type

I ran into the same error, initially I tried with default nightly-2020-10-05, then nightly-2020-10-01 and nightly-2020-10-06... but nothing is working.

Steps followed to downgrade the nightly are :

  • rustup uninstall nightly
  • rustup install nightly-
  • rustup target add wasm32-unknown-unknown --toolchain nightly-
  • WASM_BUILD_TOOLCHAIN=nightly- cargo build --release

I have tried on both Windows and Ubuntu 18.04 environment. But every time I get the same error.

Have you tried the new v2.0.1, yet? crates.io/crates/sp-io/2.0.1 It's meant to fix the build issues. - apopiak

rustup default nightly-2020-10-06 && rustup target add wasm32-unknown-unknown

Or just update to substrate 2.0.1, this issue is fixed in that version

You can use rustup to manage your version, make sure your active toolchain is like this:

$ rustup show

--------------------

stable-x86_64-apple-darwin
nightly-2020-10-05-x86_64-apple-darwin (default)
