Unexpected token HashRouter.

I followed the steps for local development from the readme and saw the following error.

> npx bower i

Hmm, I just tried a fresh clone and didn't run into this. Perhaps an issue with npm's cache? If clearing that doesn't help can you provide more info like your OS, npx pulp --version, node --version, npm --version, and npm ls webpack?

[philderbeast]

Verifying the cache as npm suggests.

> npm cache clean
npm ERR! As of npm@5, the npm cache self-heals from corruption issues and data extracted from the cache is
guaranteed to be valid. If you want to make sure everything is consistent, use 'npm cache verify' instead. On the
other hand, if you're debugging an issue with the installer, you can use `npm install --cache /tmp/empty-cache`
to use a temporary cache instead of nuking the actual one.
npm ERR!
npm ERR! If you're sure you want to delete the entire cache, rerun this command with --force.

> npm cache verify
Cache verified and compressed (~/.npm/_cacache):
Content verified: 4830 (315827706 bytes)
Index entries: 7316
Finished in 6.21s

Here are the versions while I try forcing a clean of the cache.

> npx pulp --version
Pulp version 13.0.0
purs version 0.13.6 using /.../purescript-lumi-components/node_modules/.bin/purs

> node --version
v14.4.0

> npm ls webpack
purescript-lumi-components@0.0.0 /Users/pdejoux/dev/src/increase/purescript-lumi-components
└── webpack@4.39.0

After npm cache clean --force the build reports the same error as before.

Very strange.. 🤔

@philderbeast Can you try commenting out this line? https://github.com/lumihq/purescript-lumi-components/blob/main/webpack.config.js#L99

[philderbeast]

It works for me now with that one line taken out. Thanks @spicydonuts.

[philderbeast]

I did a fresh clone and this time didn't encounter the error. I see the line I commented out last time for the build has not changed but I have now installed bower, pulp, purescript and spago globally. I did this to try other projects without such hermetic builds as this one.

[megamaddu]

Odd. I was using the npx commands so we should have been on the same local versions. I don't get why excluding unrelated folders affects whether docs/ is included 🤔
