Raspberry Pi cant get amount cores

[cronicryo]

nvm -s version
throws a message saying that it cant determine the amount of cores for make

[ljharb]

Presumably nvm install -s node?

Can you provide the output of nvm debug, nvm_get_os, cat /proc/cpuinfo, sysctl -n hw.ncpu, and psrinfo?

[cronicryo]

nvm debug

nvm --version: v0.31.1
$SHELL: /bin/bash
$HOME: /home/ratchet
$NVM_DIR: '$HOME/.nvm'
$PREFIX: ''
$NPM_CONFIG_PREFIX: ''
nvm current: v6.2.1
which node: $NVM_DIR/versions/node/v6.2.1/bin/node
which iojs: 
which npm: $NVM_DIR/versions/node/v6.2.1/bin/npm
npm config get prefix: $NVM_DIR/versions/node/v6.2.1
npm root -g: $NVM_DIR/versions/node/v6.2.1/lib/node_modules

nvm_get_os
linux

sysctl -n hw.ncpu
sysctl: cannot stat /proc/sys/hw/ncpu: No such file or directory

cat /proc/cpuinfo
cpuinfo.txt

@cronicryo Thanks!! Very helpful.

@PeterDaveHello it looks like in addition to grepping for "core id", we should count the number of "processor:" lines?

[PeterDaveHello]

hmmm ... I'll take a look at my Raspberry Pi.
@cronicryo what's the distribution of GNU/Linux you are using?

[PeterDaveHello]

Yeah, I don't have core id on Raspbian on Raspberry Pi 2, but the patch doesn't work either.
What about this:

-    NVM_CPU_THREADS="$(grep -c 'core id' /proc/cpuinfo)"
+    NVM_CPU_THREADS="$(command grep -c -E '^processor.+: [0-9]+' /proc/cpuinfo)"

This also works on the other platforms. Tested on the latest Debian/Ubuntu/Linuxmint/ArchLinux.

ok, sounds good thanks, i'll use that instead
