gcloud compute listing custom machine instances errors

[GoogleCodeExporter]

Issue running command [gcloud compute instances list].

What steps will reproduce the problem?
Create an instance with a custom CPU and MEMORY, then try and list the 
instances with gcloud.

What is the expected output? What do you see instead?
I expect to see a list of instances. I get an error: 
ERROR: gcloud crashed (ValueError): zero length field name in format

Please provide any additional information below.

Thanks for reporting this! It looks as though it's due to an incompatibility 
with Python 2.6 (the Cloud SDK requires Python 2.7, as stated on 
<https://cloud.google.com/sdk/>).

For now, you should be able to use the `--format=json` flag if you need to see 
the details, or use Python 2.7.

We'll try to get this fixed up soon.

As it turns out, we've already fixed this on our end. It should work starting 
in Cloud SDK version 0.9.88, which should be released later this week.

I've installed Python2.7 but in a different directory, can I set the path
in gcloud somewhere so it uses it?

Dave.

Ahh, sorry about that.

You can set the environment variable CLOUDSDK_PYTHON to "/path/to/python2.7".

(Shortly, any mismatched Python version will result in a warning suggesting 
this.)

Ah, I've tried that and I now get this error

I'm also using python 2.7.10

Original comment by d...@milk-vfx.com on 24 Nov 2015 at 3:17

[GoogleCodeExporter]

Odd. That points to your CLOUDSDK_PYTHON having trouble with its standard 
library (httplib is a built-in Python module, and HTTPSConnection is present in 
2.6 and 2.7.

Can you run:

   $CLOUDSDK_PYTHON -Sc 'import httplib; httplib.HTTPSConnection' && echo success

It should print 'success'. If this is the case, there's something amiss with 
the way the Cloud SDK is loading your Python. Troubleshooting this would be 
easiest if you gave an easy reproduction (i.e. letting us know the exact OS 
version, how you installed Python 2.7, etc.).

If not, we're dealing with a busted Python 2.7 installation or configuration, 
and it'll be hard to get very far.

It might be easier just to wait; 0.9.88 will be released in a few hours, 
barring unforeseen circumstances.

Ah ok, as I get this:

dave $ $CLOUDSDK_PYTHON -Sc 'import httplib; httplib.HTTPSConnection' &&
echo success

0.9.88 is out. Please let us know if you can still reproduce this issue.

[GoogleCodeExporter]

Ah, great, that fixed it.

I do get another warning but it doesn't stop it working at all and I was
getting this before:

/milk/users/dave/google-cloud-sdk/lib/googlecloudsdk/api_lib/compute/base_classe
s.py:7:
DeprecationWarning: the sets module is deprecated

Original comment by d...@milk-vfx.com on 25 Nov 2015 at 10:03

[GoogleCodeExporter]

Glad it's working for you now.

I've added an item to get rid of the use of the sets module to our work queue 
(though it's relatively low-priority)--it's an artifact of some very old code. 
That message doesn't print in 2.7.
