I'm getting the following when installing @sentry/[email protected] in a fresh node_modules (existing project). Needed for @sentry/webpack-plugin.

Is there any way I can find out more about this "unknown system error -122"? The npm debug log has no more info on the error than below.

user@host ~/project $ rm -rf node_modules
user@host ~/project $ npm install --no-save @sentry/[email protected]

> @uirouter/[email protected] install /home/user/project/node_modules/@uirouter/angularjs/node_modules/@uirouter/core
> node ./migrate/migratewarn.js

> [email protected] install /home/user/project/node_modules/strong-ursa
> node-gyp rebuild

  binding.copyFile(src, dest, flags);

I had this same error when I upgraded node to > v8

  binding.copyFile(src, dest, flags);

The solution was to upgrade my npm packages using npm audit fix I am not sure which of the many packages upgraded solved the problem
