[Nick Aquina]

Package: rollup
Version: 2.38.4-1
Severity: normal

When running `rollup --watch`, an error occurs:

(node:8675) UnhandledPromiseRejectionWarning: Error: Cannot find module
'chokidar'

(node:8675) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This
error originated either by throwing inside of an async function without a catch
block, or by rejecting a promise which was not handled with .catch(). To
terminate the node process on unhandled promise rejection, use the CLI flag
`--unhandled-rejections=strict` (see
https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id:
1)
(node:8675) [DEP0018] DeprecationWarning: Unhandled promise rejections are
deprecated. In the future, promise rejections that are not handled will
terminate the Node.js process with a non-zero exit code.

The error can be fixed by running `sudo apt install node-chokidar`.
