Unable to push to heroku. Getting a core-js post install error.

[zendevil]

While pushing on heroku, I'm getting the following error:

remote: > core-js-pure@3.6.5 postinstall /root/.nvm/versions/node/v12.18.1/lib/node_modules/karma/node_modules/core-js-pure

How to fix this?

I'm hitting a very similar error

Oops, sorry, it was due to a node update, not core-js.

I've been experiencing the same issue. Shouldn't the postinstall script call nodejs instead of node? See also https://askubuntu.com/questions/404929/node-command-not-found

node -e "try{require('./postinstall')}catch(e){}"
sh: node: command not found
