What's the problem?

Please run with --trace-warnings. Also, this issue probably belongs on the help repo because this is almost certainly an error from an npm lifecycle script. (As such, general help.)

Nothing changed

The bug is in that cdk.es5.js script. You should report it to the project where it comes from (angular?).

I'll close this out, not a node.js bug.

@bnoordhuis - I do not understand, how can this be a CDK error when npm is throwing an install promise rejection? I am experiencing the same thing here: https://github.com/npm/npm/issues/18467

I can not install flex-layout-builds too. I'm using node 8.6.0

[bnoordhuis]

@ThomasBurleson Sorry, I may have misread the error message but it's not a node.js issue. Try reporting it to npm.

[ThomasBurleson]

@bnoordhuis - Ok Thx

@Mds92 is there a follow up of this issue on the npm repo? Couldn't find one. I'm facing the same problem and couldn't find a solution as yet.

Try the following solution:
