无法运行“rustc”错误。 （生锈货物构建问题）

Question

Im trying to cargo build a file but have some issues.

I set rustup nightly-x86_64-pc-windows-msvc default but still get the error.

RUSTFLAGS='-C link-arg=-s' cargo build --release --target wasm32-unknown-unknown

Error:

error: failed to run `rustc` to learn about target-specific information

  Caused by:
  process didn't exit successfully: `rustc - --crate-name ___ --print=file-names '-C link-arg=-s' --target wasm32-unknown-unknown --crate-type bin --crate-type rlib --crate-type dylib --crate-type cdylib --crate-type staticlib --crate-type proc-macro --print=sysroot --print=cfg` (exit code: 1)
--- stderr
error: multiple input filenames provided (first two filenames are `-` and `'-C`)

Thanks for help and solutions

If you're using cmd , try using the set command to set the environment variable. You can also try using double-quotes ( " ) or no quotes.
