Description

When installing lumo through npm on a 32-bit system I get a 64-bit binary installed:

$ sudo npm install -g lumo-cljs
$ lumo 
bash: /usr/bin/lumo: det går inte att köra binär fil: Formatfel på körbar fil
$ file /usr/bin/lumo
/usr/bin/lumo: symbolic link to ../lib/node_modules/lumo-cljs/bin/lumo
$ file /usr/lib/node_modules/lumo-cljs/bin/lumo 
/usr/lib/node_modules/lumo-cljs/bin/lumo: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.24, BuildID[sha1]=a932d43de9ba2f3d322ba0aa7dd0ff79629415ae, not stripped

Research direction
The issue is that the npm package (likely a postinstall script or binary hosting) does not differentiate between 32 bit and 64 bit architectures. The fix would involve checking the architecture at install time (e.g., via process.arch in Node.js) and downloading or using the correct binary. Key files to look at are the package.json scripts field, any install.js or bin directory, and the build configuration. The maintainer may need to provide 32 bit builds or ensure the install script selects the right one.
