Snowpack with Ant Design: Import "antd" could not be resolved - reactjs

Question

I want to use Ant Design with Snowpack. I followed the And Design docs and installed antd but whenever I run my application the dependency can't be resolved.
I get the following error message:
[snowpack] Import "antd" could not be resolved.
If this is a new package, re-run Snowpack with the --reload flag to rebuild.
If Snowpack is having trouble detecting the import, add "install": ["antd"] to your Snowpack config file.
My App.tsx:
import React from 'react';
import './App.css';
import { Button } from 'antd';
function App(): JSX.Element {
return (
<div className="App">
<Button type="primary">Button</Button>
</div>
);
}
export default App;
My package.json dependencies:
"dependencies": {
"antd": "^4.6.2",
"axios": "^0.20.0",
"postcss": "^7.0.32",
"react": "^16.13.1",

"postcss-cli": "^7.1.2",

}
Am I missing something?

Make sure antd is already installed. Try this in snowpack.config.js:
module.exports = {
mount: {
public: "/",
src: "/_dist_",
},
installOptions: {
namedExports: ["antd"],
},
};
