如何从grunt模板正确访问用户的主目录？

Question

I'd like to use template in a Grunt file selection to copy a file to a user's home directory (don't ask why).

files: [ 
  {src: ['build/my_file.txt'], dest: "<%= grunt.process.HOME %>/my_file.txt"}
]

But this probably isn't right because then I get this:

Warning: An error occurred while processing a template (Cannot read property 'env' of undefined)

HOWEVER, if I force a javascript statement to be evaluated it works fine:

files: [ 
  {src: ['build/my_file.txt'], dest: "<%= grunt.process.HOME + '' %>/my_file.txt"}
]

What's the correct way to do this?

Answer 1

You might take a look at the os-homedir or userhome packages. If you don't want to use them directly, their source code is fairly concise and illustrate a cross-platform process for getting the home directory.

They mostly use process.env.HOME on Linux/MacOS, and process.env.USERPROFILE on Windows, but also have some logic to make something when those are missing.
