Grunt - 获取当前调用文件夹，而不是gruntfile当前文件夹 [英] Grunt - get current calling folder, and not gruntfile current folder

问题描述

如果我在某个文件夹/ foo中安装了Grunt，但是当前的文件夹是/ foo / bar / baz，并且我在当前文件夹中运行了grunt sometask，我该如何获得Grunt（或NodeJS） ）来确定我目前的路径？也就是说，如何以编程方式获取当我调用grunt时所在的文件夹？

If I have Grunt installed in some folder /foo, but my current folder is /foo/bar/baz, and I run "grunt sometask" from within my current folder, how can I get Grunt (or NodeJS for that matter) to determine my current path? That is to say, how can I programmatically GET the folder I was in when I called grunt?

当我使用process.cwd（）时，得到gruntfile，即foo，这不是我想要的。

When I use process.cwd(), I get the path of the gruntfile, ie, "foo", which is not what I want.

我不需要在Grunt中专门做这件事，任何基于nodejs的解决方案都可以工作。

I don't have to do this in Grunt specifically, any nodejs-based solution would work.

推荐答案

根据源代码：

According to the source code:

默认情况下，所有文件路径是相对于Gruntfile

By default, all file paths are relative to the Gruntfile

而且，voilá，这行代码显示了grunt实际上是如何将当前目录更改为Gruntfile的路径：

And, voilá, this line of code shows how grunt actually changes the current directory to the path of the Gruntfile:

process.chdir(grunt.option('base') || path.dirname(gruntfile));

然而，选项 - base 是就是这样。查看文档： http://gruntjs.com/api/grunt.file

However, option --base is there for just that. See docs: http://gruntjs.com/api/grunt.file

如果您不需要从 Gruntfile内执行操作，只需运行一个脚本来捕获 process.cwd（）然后 execs grunt。

If you don't need to do it from inside the Gruntfile, simply run a script that captures the process.cwd() and then execs grunt.

请参阅： https://www.npmjs.com/package/exec

var exec = require('exec');

process.cwd(); // Will have your current path

exec(['grunt', 'mytask'], function(err, out, code) {
  if (err instanceof Error)
    throw err;
  process.stderr.write(err);
  process.stdout.write(out);
  process.exit(code);
});
