[Pkg-javascript-devel] Bug#962737: handlebars: Does not declare its dependencies

[nandhp]

Package: handlebars
Version: 3:4.1.0-1
Severity: serious
Justification: Policy 3.5

Dear Maintainer,

The package handlebars does not declare any dependencies, except on
nodejs itself. However, the handlebars command fails to run unless I
also install at least node-optimist, node-async, and node-source-map:

$ handlebars
internal/modules/cjs/loader.js:638
    throw err;
    ^

The version in unstable also does not declare any dependencies, so I
expect this problem is still present there.

Thanks.
