fresh install of single-spa-react is missing lib and parcel directories

[splomax]

Hi, I'm working on a project that uses single-spa and single-spa-react. I had to remove my node_modules folder and do a fresh install. After doing so, my project started throwing errors on start, specifically complaining about this:

ERROR in ./src/redacted.js 3:0-46
Module not found: Error: Can't resolve 'single-spa-react' in 'C:\projects\redacted\src'
resolve 'single-spa-react' in 'C:\projects\redacted\src'
  Parsed request is a module
  using description file: C:\projects\redacted\package.json (relative path: ./src)
    Field 'browser'

Here's how I'm attempting to access single-spa-react in the file it's complaining about:

...
import singleSpaReact from 'single-spa-react';
...
const lifecycles = singleSpaReact({
    React,
    ReactDOM,
    rootComponent: Root,
    errorBoundary(err, info, props) {
        // Customize the root error boundary for your microfrontend here.
        return null;
    },
});
...

I tried several fresh installs, cleaning my cache, etc., and couldn't get rid of this error. I have several other projects that use single-spa-react, so I decided to investigate their node_modules/single-spa-react directories to see if there were any discrepancies. Here's what I found. In an older project, node_modules/single-spa-react looks like this:

node_modules
--single-spa-react
----lib
----parcel
----types
--LICENSE
--package.json
--README.md

However, the repo with the fresh install looks like this:

node_modules
--single-spa-react
----types
--LICENSE
--package.json
--README.md

The lib and parcel directories are missing. To make sure this is what was causing the issue, I replaced node_modules/single-spa-react with the copy from the older repo, and that did fix the problem.

In case there was an issue with the machine I'm working on, I recreated this issue on a different computer in a completely fresh npm project. The package.json looks like this:

{
  "name": "single-spa-react-test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "single-spa-react": "^5.1.0"
  }
}

This results in the same thing - single-spa-react-test/node_modules/single-spa-react is missing the lib and parcel directories. Can I get any guidance on what I can/should do to fix this? Thanks!
