how to determine whether I have 64bit or 32 bit node executable installed?

Question

On my windows pc I have nodejs installed. I would like to determine whether it is 64 bit or 32 bit. How can one determine that? I executed

node --help 

but that does not seem to have any option to give me the desired information.

Answer 1

Run this from the command line:

node -p "process.arch" 

It will return 'arm', 'arm64', 'ia32', 'mips','mipsel', 'ppc', 'ppc64', 's390', 's390x', 'x32', or 'x64'.

Answer 2

If node is installed and executable you can simply run

c:\> node -p "process"     

and you should see the content of the process variable formatted. There the keys arch and platform indicates your operating system. In the example below it's an Windows 7 x64

{     title : 'Administrator: C:\\Windows\\System32\\cmd.exe - node  ',     version : 'v0.10.36',     moduleLoadList :     [   'Binding evals',         ...         'Binding signal_wrap',         'NativeModule string_decoder'],     versions : {         http_parser : '1.0',         node : '0.10.36',         v8 : '3.14.5.9',         ares : '1.9.0-DEV',         uv : '0.10.30',         zlib : '1.2.8',         modules : '11',         openssl : '1.0.1l'     },     arch : 'x64',     platform : 'win32',     argv : ['node'],     execArgv : [],     env : {         ALLUSERSPROFILE : 'C:\\ProgramData',         HOMEDRIVE : 'C:',         JAVA_HOME : 'C:\\Program Files\\Java\\jdk1.8.0_05',         NODEJS : 'C:\\Program Files (x86)\\nodejs\\',         NUMBER_OF_PROCESSORS : '4',         OS : 'Windows_NT',         Path : 'C:\\ProgramData\\Oracle\\Java\\javapath;C:\\Windows\\system32;C:\\Windows;C:\\Windows\\System32\\Wbem;',         PATHEXT : '.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC;.PY',         PROCESSOR_ARCHITECTURE : 'AMD64',         PROCESSOR_IDENTIFIER : 'Intel64 Family 6 Model 42 Stepping 7, GenuineIntel',         PROCESSOR_LEVEL : '6',         PROCESSOR_REVISION : '2a07',         ProgramData : 'C:\\ProgramData',         ProgramFiles : 'C:\\Program Files',          'ProgramFiles(x86)' : 'C:\\Program Files (x86)',         ProgramW6432 : 'C:\\Program Files',         PROMPT : '$P$G',         PUBLIC : 'C:\\Users\\Public',         PYTHON : 'C:\\Python34',         SESSIONNAME : 'Console',         SystemDrive : 'C:',         SystemRoot : 'C:\\Windows',         windir : 'C:\\Windows',         windows_tracing_flags : '3'     },     features : {         ...     },     config : {         ...     } }
