AttributeError: module 'pyparsing' has no attribute 'downcaseTokens'

Starting today, when I import googlecloudprofiler, I get this traceback;

Traceback (most recent call last):

Looks like the latest pyparsing release changed the name of these functions:
https://pyparsing-docs.readthedocs.io/en/latest/whats_new_in_3_0_0.html#other-discontinued-features

upcaseTokens and downcaseTokens - convert to using pyparsing_common.upcase_tokens and downcase_tokens

As a workaround, I having pinned pyparsing in my requirements.txt:

pyparsing==2.4.7

Thanks for reporting this. Looks like the root cause is being tracked here.

We can possibly add some workaround in cloud-profiler-python while waiting for that to be resolved.

I'm currently occupied with other tasks, but I'll do my best to take a look at this in 1-2 weeks. If your workaround starts breaking badly, please let us know.

I think this is fixed in httplib 0.20.2 (httplib2/httplib2#207 (comment)). I was able to import googlecloudprofiler successfully after installing google-cloud-profiler in a clean virtualenv.
