# RustPython wasm32 build without JS To test, build rustpython to wasm32-unknown-unknown target first. ```shell cd rustpython-without-js # due to `.cargo/config.toml` cargo build cd .. ``` Then there will be `rustpython-without-js/target/wasm32-unknown-unknown/debug/rustpython_without_js.wasm` file. Now we can run the wasm file with wasm runtime: ```shell cargo run --release --manifest-path wasm-runtime/Cargo.toml rustpython-without-js/target/wasm32-unknown-unknown/debug/rustpython_without_js.wasm ```
