Unterminated string constant

[allthesignals]

(This is cross-posted from the issue here FortAwesome/ember-fontawesome#143, I am opening an issue here in hopes of finding some hints on where in the stack this might be coming from)

Describe the bug
I've run into a really baffling problem where I cannot get my app to build due to an "unterminated string constant" during the rollup process.

To Reproduce
Insert a URL to your test case - use codepen.io, jsfiddle.net, jsbin.com, codesandbox.io, or whatever.

Describe any details about the test case that we need to know like "whatever you do, don't click the red button."

Here's my yarn.lock: https://gist.github.com/allthesignals/9ff91ab416910c26edfb1278f2cbcb3f#file-yarn-lock

Here are the contents of the log file.

Hi!

Thanks for being part of the Font Awesome Community.

Will leave this open for feedback from the community, but I can't personally help, sorry

[caprica-Six]

Experienced the same issue here as well.
Font-awesome versions:

"@fortawesome/fontawesome-free": "^5.12.1",
    "@fortawesome/fontawesome-svg-core": "^1.2.28",
    "@fortawesome/free-solid-svg-icons": "^5.13.0",
    "@fortawesome/react-fontawesome": "^0.1.9"

So, what actually fixed it was:

• rm -rf node_modules
• npm cache verify
• kill terminal
• kill VSCode
• re-start machine
  worked!

The index.es.js file seems to be truncated for some reason.

I resolved with the following steps:

1. rm yarn cache dir
2. npm cache rm --force
3. rm yarn.lock
4. rm -rf node_modules
5. yarn install

I'm not sure which one of these fixed the issue, but hope this helps.

In addition to the steps from previous two answers, running yarn cache clean helped me
