How can one verify if the `canvas.node` file actually exists in the expected `../build/release/` directory after attempting to resolve the error?

After running `npm install` or `npm rebuild canvas`, you can manually check for the file. Navigate to your project's `node_modules/canvas/build/Release` directory. Inside this `Release` folder, you should find the `canvas.node` file. If it's missing, or if the `build` directory itself is absent, empty, or lacks the `Release` subdirectory, it confirms that the compilation process failed to produce the necessary native module. Review the `npm install` output for any `node-gyp` compilation errors if the file is not present.
