Answer 1

opencv4nodejs installation through auto build seems broken with Node.js current version (15.7.0). Until a possible fix, try with an earlier version of Node.js, 14.15.4 should work.

Answer 2

opencv4nodejs dose not support to the current node version yet. You can use nvm (Node Version Manager) to handle your node version. You can switch your node version using nvm

If you switch to new version then run

npm rebuid

Inside your node package then it rebuild to the new version.
