Failed to modify the code from this file

./node_modules/@polymer/lit-element/lit-elelment.js:12

Sorry don't know what build you're running and why it's trying to modify that file.

[shenzekun]

same problem! I use create-react-app create a program and use wired-elements,but when I run yarn bulid,appear this(I didn't modify ./node_modules//lit-elelment.js this file)

[pshihn]

This is likely because the target of the build is set to ES5. There may be other solutions out there. Don't think it is specific to wired-elements. But anyone using lit-element

Same problem here 👍

[sashahavia]

Same here. Did anyone find the solution?

[pshihn]

The easiest work around is the use the bundled version in your app

<script src="https://unpkg.com/[email protected]/dist/wired-elements.bundled.min.js"></script>

This demo CodeSandbox shows usage of wired-elements in create-react-app.
