How to set working directory for Node.js on windows?
提问by Christoph
I just installed node.js for windows and it really was a breeze to get it running. I would like to use it as part of my build process to combine several files together like so:
我刚刚为 Windows 安装了 node.js，让它运行起来真的很容易。我想将它用作构建过程的一部分，将多个文件组合在一起，如下所示：
// settings
var FILE_ENCODING = 'utf-8',
EOL = '\n',
DIST_FILE_PATH = 'dist/myAwesomeScript.js';
// setup
var _fs = require('fs');
function concat(fileList, distPath) {
var out = fileList.map(function(filePath){
return _fs.readFileSync(filePath, FILE_ENCODING);
});
_fs.writeFileSync(distPath, out.join(EOL), FILE_ENCODING);
console.log(' '+ distPath +' built.');
}
concat([
'foo/bar.js',
'foo/lorem.js',
'foo/maecennas.js'
], DIST_FILE_PATH);
This really works like a charm. However it does only work if I place all my scripts into the nodejs directory which is C:\Program Files (x86)\nodejs and start the cmd process with admin rights.
这真的很有魅力。但是，只有将所有脚本放入 nodejs 目录 C:\Program Files (x86)\nodejs 并以管理员权限启动 cmd 进程时，它才有效。
But I need to have my project files in another directory ( say D:\git\projectx\ ) and would like to be able to run: node.exe D:\git\projectx\combine.js. Unfortunatly things doesn't work that way because node.exe will look for the files within it's own directory which is C:\Program Files (x86)\nodejs. There must be away to start the nodejs process and tell it to use another directory as its working directory, am I wrong?
但是我需要将我的项目文件放在另一个目录中（比如 D:\git\projectx\）并且希望能够运行：node.exe D:\git\projectx\combine.js。不幸的是，事情不会那样工作，因为 node.exe 将在它自己的目录中查找文件，即 C:\Program Files (x86)\nodejs。必须启动nodejs进程并告诉它使用另一个目录作为其工作目录，我错了吗？
UPDATE

As someone pointed out on IRC. The solution to my problem was rather simple. Just cdinto D:\git\projectxand then use node.exe combine.js. This makes it so that the current directory inside your script points to D:\git\projectx
正如有人在 IRC 上指出的那样。我的问题的解决方案相当简单。只需cd进入D:\git\projectx然后使用node.exe combine.js. 这使得脚本中的当前目录指向D:\git\projectx
However, I'm accepting Luke's answer since it seems to be also true ;-)
但是，我接受卢克的回答，因为它似乎也是正确的 ;-)

You can set the current working directory using process.chdir, using Unix-style pathnames:
您可以使用process.chdir设置当前工作目录，使用 Unix 样式的路径名：
process.chdir('/temp/foo');
I'm not sure how to specify the drive prefix (D:) though.
不过，我不确定如何指定驱动器前缀 ( D:)。

You can always use __dirnameto represent the directory of the script you are in...
您始终可以使用__dirname来表示您所在脚本的目录...
process.chdir(__dirname);

process.chdir('D:\git\projectx')

Actually it's
其实是
process.chdir('D:\\git\projectx')
