Following tip from #47, things work:

12:03 $ sudo npm install --unsafe-perm -g @juxt/mach
/usr/local/bin/mach -> /usr/local/lib/node_modules/@juxt/mach/bin/mach

> lumo-cljs@1.7.0 install /usr/local/lib/node_modules/@juxt/mach/node_modules/lumo-cljs
> node scripts/npm_install.js || nodejs scripts/npm_install.js
