This change causes unit-tests to fail as mkdir fails when the directory already exists.

[~]$ tools/run-tests.py unit-tests
Traceback (most recent call last):
  File "tools/run-tests.py", line 25, in <module>
    main()
  File "tools/run-tests.py", line 13, in main
    os.makedirs(node_modules_dir)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/os.py", line 157, in makedirs
    mkdir(name, mode)
OSError: [Errno 17] File exists: '/Volume/Data/OpenSource/Websites/perf.webkit.org/node_modules'

This fails when the directory already exists. Should check first if the directory exists. e.g.:

if not os.path.exists(node_modules_dir):
    os.makedirs(node_modules_dir)

You are right. I'll land the fix.
