问题
I have no luck building the jQuery (git) using grunt.
Everything went smoothly till the actual grunt command which outputs as following:
grunt --config Gruntfile.js
Running "update_submodules" task
TypeError: Cannot call method 'spawn' of undefined

Any hints appreciated. Installed all the needed npm dependiences and so on. It's just the build process that ends up being aborted.
回答1:
You need to run latest dev version of grunt, which you can get with npm install grunt@master
Also make sure you have uninstalled the old global grunt npm uninstall -g grunt and installed grunt-cli globally npm install -g grunt-cli.
