Just checked; This appears to work on Linux, so this likely a Windows-specific issue. Looks like this issue has something to do with how y'all are constructing the absolute path to the bin script.

(Linux constructs from the system-level bin script, and Windows constructs from the package-level bin script.)

Dug into this a bit more:

This is happening because on Unix, global binaries are a symlink from /usr/bin/$PACKAGE -> /usr/lib/node_modules/$PACKAGE/bin/$PACKAGE, so $DIR will be /usr/bin, but on Windows, it'll be $HOME/AppData/Roaming/npm/node_modules/npm-lazy-mirror/bin.

This means that on Unix, the bin command will (correctly) be

node /usr/bin/../lib/node_modules/npm-lazy-mirror/server.js

But on Windows, it will be

node $HOME/AppData/Roaming/npm/node_modules/npm-lazy-mirror/bin/../lib/node_modules/npm-lazy-mirror/server.js
