Actual:

Traceback (most recent call last):
  File "/home/phanect/google-cloud-sdk/lib/enum/__init__.py", line 364, in __getattr__
    return cls._member_map_[name]
KeyError: '_convert'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/phanect/google-cloud-sdk/./lib/googlecloudsdk/gcloud/gcloud.py", line 12, in <module>
    import signal

    _IntEnum._convert(
  File "/home/phanect/google-cloud-sdk/lib/enum/__init__.py", line 366, in __getattr__
    raise AttributeError(name)
AttributeError: _convert

What is the output of 'gcloud info'?
See above

Please provide any additional information below.
This happens because gcloud runs Python code with `python` command, although it 
is incompatible with Python 3.
In environments which `python` points `python3` like mine, above error occurs.

As a workaround, I modified google-cloud-sdk/bin/gcloud.

This issue also happen in gsutil.
The workaround is the same.

Thanks. All of our shell wrapper scripts are generated with a common preamble. 
Fixing the preamble will ripple down to all of the wrappers at build time.

Sorry for the silence here--this has been fixed for a couple of releases.
