Answer 1

这将通过安装Xcode 7来解决。只需在Xcode上运行更新，神奇的是，一切都会再次起作用。

Answer 2

Unfortunately for me, installing Xcode 7 didn't fix it. I had to downgrade from node 4.2 to 0.12.7. At this point in time, Mean.js only supports Node 0.10.x. (Note that Node jumps from 0.12.7 to 4.0.)

I use n to manage Node versions. To install n

$ npm install -g n 

Then install Node 0.12.7 via n

$ n 0.12.7 

Enter n in the terminal to choose Node version.

$ n

Use arrow to select a version and press enter.

Then try

$ yo meanjs

This SO post explains in detail on how to change to an older version of node.js.
