Where to place JS files for NodeJS to see them
提问by B?dlen
I've just installed NodeJS on my Mac, and i got it working in the terminal, using inline scripting like "console.log('Hello world'); works fine.
我刚刚在我的 Mac 上安装了 NodeJS，我让它在终端中工作，使用内联脚本，如“console.log('Hello world'); 工作正常。
But where do i place JS files for NodeJS to find them? Can i specify the root folder NodeJS to look for file in?
但是我应该把 NodeJS 的 JS 文件放在哪里才能找到它们呢？我可以指定根文件夹 NodeJS 来查找文件吗？
I followed this guide: http://nodeguide.com/beginner.html#learning-javascriptbut i cannot get any of the samlpe to work where i reference a script file.
我遵循了本指南：http: //nodeguide.com/beginner.html#learning-javascript 但我无法让任何 samlpe 在我引用脚本文件的地方工作。

You put them in whatever folder you want. It is common practice to put each application in a different folder.
你把它们放在你想要的任何文件夹中。通常的做法是将每个应用程序放在不同的文件夹中。
Then you run node.js like this:
然后像这样运行 node.js：
node /path/to/file.js
Or like this:
或者像这样：
cd /path/to/
node file.js
Where file.jsmight look something like this:
哪里file.js可能看起来像这样：
console.log('hello world');

You'll have to navigate to the correct folder "manually", in the Node Command Line Interface (CLI).
您必须在节点命令行界面 (CLI) 中“手动”导航到正确的文件夹。
If you need to change drives, type the drive letter and a colon to switch to that drive, like so;
如果您需要更改驱动器，请键入驱动器号和冒号以切换到该驱动器，如下所示；
C:>(<- this is the line prompt, yeah? Just add this after it -> D:
C:>(<- 这是行提示，是吗？在它后面加上这个 -> D:
That changes the drive. Now write cd (CD = "Change Directory") and the name of the direcotry you want to go to the directory your stuff is in:
这改变了驱动器。现在写 cd (CD = "Change Directory") 和你想要进入你的东西所在目录的目录的名称：
D:>(<- the new prompt. Write something like this after it: ->) cd myprosject\subfoldernameD:\myproject\subfoldername>(<- your new line prompt - if "myproject\subfoldername" exists)
D:>(<- 新提示。在它后面写这样的东西：->) cd myprosject\subfoldername D:\myproject\subfoldername>（<- 你的新行提示 - 如果“myproject\subfoldername”存在）
now ask node to execute your script (that is stored in myproject\subfoldername, like so;
现在要求节点执行您的脚本（存储在 myproject\subfoldername 中，像这样；
D:\myproject\subfoldername> node helloworld.js
D:\myproject\subfoldername> 节点 helloworld.js
Remember to write "node" first - otherwise the command won't go to node, but to the OS, which will probably just open up the js file in a text editior instead of running the goodies inside.
记住先写“节点” - 否则命令不会转到节点，而是转到操作系统，它可能只会在文本编辑器中打开 js 文件，而不是在里面运行好东西。

It is very easy.. Go to your command line. navigate to the file location.. then simply run the node helloworld.
这很容易.. 转到您的命令行。导航到文件位置.. 然后只需运行节点 helloworld。

I'm not sure I understand. it doesnt 'look' anywhere for your .js files you point at them when you run node. Like so, on the command line:
我不确定我是否理解。当您运行 node.js 文件时，它不会在任何地方“查找”您指向它们的 .js 文件。像这样，在命令行上：
node mynodeapp.js
If you're meaning where does it look for your .js files as modules, when requirign them, like so:
如果你的意思是在哪里寻找你的 .js 文件作为模块，那么在重新定义它们时，就像这样：
var mymodule = require("mymodule");
Then it will look inside a folder names node_modules. But I'm sure you're looking for my first example above.
然后它会在文件夹名称中查找node_modules。但我相信你正在寻找我上面的第一个例子。
