Updating the nightly version of rust gives error on module path:

While importing the module it now gives following error:

#[wasm_bindgen(module = "/src/package.js")]
extern "C" {
    #[wasm_bindgen]
    pub fn helloworld();

    = note: this lint makes sure the compiler doesn't get stuck due to infinite loops in const eval.
            If your compilation actually takes a long time, you can safely allow the lint.
