Any Help..?

Your version of pyasn1 it too old. I'm not sure why pip install --upgrade pyasn1 isn't fixing it, but that is the root of the problem. pyans1-modules requires pyasn1>=0.4.1,<0.5.0.

It's even weirder that your pip freeze output lists 0.4.2 as the pyans1 version, so I really don't know what's occurring here.

I could not reproduce with Ubuntu 16.04 and the apt-provided Python 3.5. My pip freeze looks like this:

cachetools==2.0.1
certifi==2018.4.16
chardet==3.0.4
google-api-core==1.1.1
google-auth==1.4.1
google-cloud-core==0.28.1
google-cloud-storage==1.8.0
google-resumable-media==0.3.1
googleapis-common-protos==1.5.3
idna==2.6
pkg-resources==0.0.0
protobuf==3.5.2.post1
pyasn1==0.4.2
pyasn1-modules==0.2.1
pytz==2018.4
requests==2.18.4
rsa==3.4.2
six==1.11.0
urllib3==1.22

I'm going to go ahead and close this, but I'm happy to keep discussing and working through this with you.
