Same problem as you...
Have you find any solutions?

[lelemka0]

have the same issue

i found a temporary solution, which requires you to install node and npm.
goto <python install dir>/Lib/site-packages/pythonmonkey/node_modules and run npm install core-js

[Smawexi]

Can this error be resolved in the next version. I also have this error when using.

@Smawexi @lelemka0 @francescocassini can you provide a full reproducer? How is core-js configured into this?

[lelemka0]

@philippedistributive I made some attempts and found that the problem always occurs after upgrading.
The loss of core-js occurred when upgrading from 0.2.1 to 0.2.2, because pminit was not upgraded at the same time.
core-js is a new dependency in 0.2.2, so it is missing. If the js dependency does not change when the module is upgraded, there will be no exception.

I think the problem comes from here, it doesn't make a requirement on the version of pminit.

PythonMonkey/pyproject.toml

Line 33 in 9f52f58

pminit = { version = "*", allow-prereleases = true }

As a temporary workaround, use pip install pythonmonkey --force-reinstall instead of pip install pythonmonkey --upgrade when upgrading modules.

I am also encountering with the same issue with latest version 0.4.0 :(
