Uncaught TypeError: _App.default is not a constructor

[tomwayson]

After pulling and running npm i && npm run dev, I see the following warning in the terminal:

Parser "parcel-plugin-svelte/lib/svelte-asset.js" failed to initialize when processing asset "src/components/App.svelte". Threw the following error:
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './compiler.js' is not defined by "exports" in /Users/tom/code/svelte-template-parcel/node_modules/svelte/package.json

I then load http://localhost:1234/ and I see a blank screen and the following error in the console:

main.js:3 Uncaught TypeError: _App.default is not a constructor
    at Object.parcelRequire.main.js.~/components/App.svelte (main.js:3)
    at newRequire (main.1f19ae8e.js:47)
    at main.1f19ae8e.js:81
    at main.1f19ae8e.js:120

I have parcel-bundler@1.12.4 installed globally.
