npm install -g gatsby-cli, core-js, error

[4096void]

When I run npm install -g gatsby-cli,

Results below:

npm WARN deprecated [email protected]: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.
npm ERR! cb() never called!

Or can I just update core-js@latest to fix this?
Thanks in advance.

An update to core-js is being tracked here: #15601

Are you able to use the gatsby-cli, this shouldn't be an error but just a warning

After few times, it works fine now, seems not related to core-js@<3
