I recently deployed a new cluster, which pulled the latest version of this library (1.4.0). My workers when doing `from google.cloud import storage` now fail with the following error:\r\n\r\n```\r\n  File \"/usr/local/lib/python3.4/dist-packages/google/cloud/storage/__init__.py\", line 37, in \u003cmodule\u003e\r\n    from google.cloud.storage.batch import Batch\r\n  File \"/usr/local/lib/python3.4/dist-packages/google/cloud/storage/batch.py\", line 30, in \u003cmodule\u003e\r\n    from google.cloud import exceptions\r\n  File \"/usr/local/lib/python3.4/dist-packages/google/cloud/exceptions.py\", line 24, in \u003cmodule\u003e\r\n    from google.api.core import exceptions\r\n  File \"/usr/local/lib/python3.4/dist-packages/google/api/core/exceptions.py\", line 43, in \u003cmodule\u003e\r\n    @six.python_2_unicode_compatible\r\nAttributeError: 'module' object has no attribute 'python_2_unicode_compatible'\r\n```\r\n\r\nWhich is probably because there is no `six` package declared in the dependencies of this project?\r\n\r\nA workaround is to ensure that six==1.10.0 is installed (I don't know exactly which version introduced the attribute `python2_unicode_compatible`).\r\n\r\nThis is the information of the system where the bug occurs:\r\n```\r\n$ uname -a\r\nLinux dojeda-test-job-cluster-w-1 3.16.0-4-amd64 #1 SMP Debian 3.16.43-2+deb8u2 (2017-06-26) x86_64 GNU/Linux\r\n$ cat /etc/issue\r\nDebian GNU/Linux 8 \\n \\l\r\n\r\n$ pip freeze\r\nbackports.ssl-match-hostname==3.5.0.1\r\ncachetools==2.0.1\r\ncertifi==2017.7.27.1\r\nchardet==3.0.4\r\ncolorama==0.3.2\r\ndocker==2.5.1\r\ndocker-pycreds==0.2.1\r\ngoogle-auth==1.0.2\r\ngoogle-cloud-core==0.27.0\r\ngoogle-cloud-storage==1.4.0\r\ngoogle-resumable-media==0.2.3\r\ngoogleapis-common-protos==1.5.2\r\nhtml5lib==0.999\r\nidna==2.6\r\nprotobuf==3.4.0\r\npyasn1==0.3.2\r\npyasn1-modules==0.0.11\r\npygobject==3.14.0\r\npython-apt==0.9.3.12\r\nrequests==2.18.4\r\nrsa==3.4.2\r\nsix==1.8.0\r\nunattended-upgrades==0.1\r\nurllib3==1.22\r\nwebsocket-client==0.44.0\r\n```\r\n\r\nHere is a working pip freeze:\r\n```\r\nbackports.ssl-match-hostname==3.5.0.1\r\ncachetools==2.0.1\r\ncertifi==2017.7.27.1\r\nchardet==3.0.4\r\ncolorama==0.3.2\r\ndocker==2.5.1\r\ndocker-pycreds==0.2.1\r\ngoogle-auth==1.0.2\r\ngoogle-cloud-core==0.27.0\r\ngoogle-cloud-storage==1.4.0\r\ngoogle-resumable-media==0.2.3\r\ngoogleapis-common-protos==1.5.2\r\nhtml5lib==0.999\r\nidna==2.6\r\nprotobuf==3.4.0\r\npyasn1==0.3.2\r\npyasn1-modules==0.0.11\r\npygobject==3.14.0\r\npython-apt==0.9.3.12\r\nrequests==2.18.4\r\nrsa==3.4.2\r\nsix==1.10.0\r\nunattended-upgrades==0.1\r\nurllib3==1.22\r\nwebsocket-client==0.44.0\r\n```\r\n","author":{"url":"https://github.com/dojeda","@type":"Person","name":"dojeda"},"datePublished":"2017-08-25T08:29:24.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/3880/google-cloud-python/issues/3880"}
