how to determine whether I have 64bit or 32 bit node executable installed?
提问by runtimeZero
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
在我的 Windows 电脑上，我安装了 nodejs。我想确定它是64位还是32位。如何确定这一点？我执行了
node --help
but that does not seem to have any option to give me the desired information.
但这似乎没有任何选项可以为我提供所需的信息。

Run this from the command line:
从命令行运行：
node -p "process.arch"
It will return 'arm', 'ia32', or 'x64'.
它将返回“arm”、“ia32”或“x64”。

If node is installed and executable you can simply run
如果节点已安装且可执行，您只需运行
c:\> node -p "process"
and you should see the content of the processvariable formatted.
There the keys archand platformindicates your operating system. In the example below it's an Windows 7 x64
你应该看到process格式化的变量的内容。那里有键arch和platform指示您的操作系统。在下面的例子中，它是一个Windows 7 x64

If it's on Windows OS, just go an old-school way.. by using Windows Task Manager.
如果它在 Windows 操作系统上，只需使用老派的方式..使用Windows 任务管理器。
Here is my attempt:-
这是我的尝试：-
Simply run nodefrom command prompt.
只需node从命令提示符运行。
C:\> node
C:\> node
This will put node into REPL mode (indicated by >symbol).
Now open Task Manager (Ctrl+Shift+Esc) to see node.exeprocess details. Mine is on Windows 10 64-bit with node 32-bit installed. Make sure you enable 'Platform' column to see 32-bit/64-bit information.
这将使节点进入 REPL 模式（由>符号表示）。现在打开任务管理器 (Ctrl+Shift+Esc) 以查看node.exe进程详细信息。我的是安装了 32 位节点的 Windows 10 64 位。确保启用“平台”列以查看 32 位/64 位信息。

在 mac
$ node

in windows
在窗户里
c:\> node

Well the way I am suggesting is not at all a good way . You can go over to C: then go to Program Files and search nodejs folder there . If it is found then you are running 64 bit version else check on Program Files (x86) . If it is found there then you are running 32 bit version.
那么我建议的方式根本不是一个好方法。您可以转到 C: 然后转到 Program Files 并在那里搜索 nodejs 文件夹。如果找到，那么您正在运行 64 位版本，否则请检查 Program Files (x86) 。如果在那里找到，那么您正在运行 32 位版本。

This likely doesn't directly solve your problem, as I don't know the best way to get the same behavior on Windows, but using the filecommand on a Unix or Linux system will tell you the processor architecture of an executable:
这可能不会直接解决您的问题，因为我不知道在 Windows 上获得相同行为的最佳方法，但是file在 Unix 或 Linux 系统上使用该命令会告诉您可执行文件的处理器架构：
$ file `which node`
/usr/local/bin/node: Mach-O 64-bit executable x86_64
If you have Cygwin installed, I'm pretty sure that it provides a filecommand, or else you could check online for similar programs that work on Windows.
如果您安装了 Cygwin，我很确定它提供了一个file命令，否则您可以在线检查在 Windows 上运行的类似程序。

Just start node interpreter by running node. then in that, process.envgives a json with all the information you require. My try has a PROCESSOR_ARCHITECTURE: 'AMD64'entry in that.
只需通过运行启动节点解释器node。然后在其中process.env提供一个包含您需要的所有信息的 json。我的尝试中有一个PROCESSOR_ARCHITECTURE: 'AMD64'条目。
I also find
我也发现
ProgramFiles: 'C:\\Program Files', 'ProgramFiles(x86)': 'C:\\Program Files (x86)'ProgramW6432: 'C:\\Program Files'
ProgramFiles: 'C:\\Program Files', 'ProgramFiles(x86)': 'C:\\Program Files (x86)'ProgramW6432: 'C:\\Program Files'

Enter the node REPL using the 'node' command.
使用“node”命令输入节点 REPL。
The prompt will change to >
提示将变为 >
Then use the following to get the desired info-
然后使用以下内容获取所需的信息-
- require('process').arch ==> this will give the node architecture version.
- require('process').platform ==> this will give the architecture of the compilation platform
- require('process').release and require('process').release.libUrl ==> also gives information about the version and achitecture
- require('process').config.variables.host_arch ==> this will also give the node architecture version.
- require('process').arch ==> 这将给出节点架构版本。
- require('process').platform ==> 这将给出编译平台的架构
- require('process').release 和 require('process').release.libUrl ==> 还提供有关版本和架构的信息
- require('process').config.variables.host_arch ==> 这也将给出节点架构版本。
