LRU Cache is not a constructor issue in Microsoft Office addin

[Peterhague]

Hi I'm developing an Excel addin via the yeoman generator, which includes LRU Cache package as a dependency (not sure of which of the dependencies in pakcage.json). The code now throws an error (Typeerror: LRU Cache is not a constructor) on running npm start to run the app.

The code stopped working some time between evening GMT of Thursday and 9am GMT Friday - I can see that there was a new version of LRU Cache around that time so assume the issue is related to that.

Can you advise at all?

Many thanks

Peter

What does npm ls lru-cache output?

What package manager are you using?

Something in your dep tree is getting a version that it doesn't know how to use. This is likely a package manager issue.
