It does download stuff during package(). This must not happen. An internet connection must not be assumed after finishing prepare() and pkgver() (i.e., neither in build(), nor in check(), nor in package()).

So, please make sure that everything needed to build the package gets downloaded by the source-array (thus the specifications of download agents the user has done in the makepkg.conf are honoured) and via makedepends. Only as an exception you can also use the prepare()-function for it.

Thanks for maintaining!

Thank you all! It should now conflict with trello, and I've updated to 0.3.0.

@mprom Version 0.3.0 has just been released to NPM which makes refreshing more efficient and removes this error

Should conflict with package trello (both provide the file /usr/bin/trello, which does quite different things in both packages).

When I try to do trello refresh after being authorized etc. I get this error:

▶ trello refresh
Organization, board, list, and user cache refreshed
/usr/lib/node_modules/trello-cli/src/translator.js:114
            throw err;
            ^
