Error while build netlify cms plugin

[Jaikant]

I am getting the below error while building the netlify cms plugin.

This was working a couple of weeks back. Not sure what went wrong.

@erquhart could you help / point me in the right direction?

@Jaikant there's a pending fix for this, see #4046. And for a temporary workaround #4031.

Closing as it is a duplicate! Sorry about that.
