Unknown signal 33 - Githubissues

I'm installing nodejs and npm@4.2.0 inside a chroot for an armhf debootstrap. When I do npm i -g npm@4.2.0 something inside uid-number dies with the following:

# npm update -g --verbose
SyntaxError: Unexpected end of JSON input
    at Object.parse (native)
    at /usr/lib/node_modules/npm/node_modules/uid-number/uid-number.js:43:18

    at Socket.emit (events.js:188:7)
    at Pipe._handle.close [as _onclose] (net.js:498:12)

I dug a little deeper and when I run get-uid-gid.js:

# node /usr/lib/node_modules/npm/node_modules/uid-number/get-uid-gid.js
[ 0, 0 ]
Unknown signal 33

version info:

# node --version
v6.9.5
# npm --version
3.10.10

This is preventing me from doing npm i -g for anything inside the chroot.

npm / uid-number
