Deleting a key from a dictionary while iterating over it raises an exception in Python 3

The problem is at line

node-gyp/gyp/pylib/gyp/input.py

Line 2288 in 038b4a3

# Now drop all the abstract ones.

In Python 3, it's not allowed to delete a key from a dictionary while iterating over it.
Example while trying to npm install --save gl:

> gl@4.4.0 install /home/alex/Documents/code/editor-renderer/node_modules/gl
> prebuild-install || node-gyp rebuild
