Problem using add-metadata on google compute engine

[GoogleCodeExporter]

What steps will reproduce the problem?
1.- Create a new vm on compute engine with: centos6 , name "test" , and all 
permissions with service account activated.
2.-Try to add a meta data, example: 
 /usr/local/bin/gcloud compute instances add-metadata "portal" --project "test" --zone "us-central1-f" --metadata "started_timestamp=2015-25-22 08:40:27"

What is the expected output? What do you see instead?
 I should see the metadata added but shows me: AttributeError: 'FieldList' object has no attribute '_FieldList__field'

What is the output of 'gcloud info'? --http-log:

If I do this in my local computer it works find, this problem only happens on 
the compute engine vm.

Thanks for reporting.  This is a known issue that we're working on.  As a work 
around, you can install python 2.7.

Cheers,
Jeff

Yes, I did this, and now is working.

yum -y groupinstall "Development tools";
yum -y install zlib-devel
yum -y install bzip2-devel
yum -y install openssl-devel
yum -y install ncurses-devel
yum -y install sqlite-devel

#Instaling python2.7.6 for gcloud, if we set de defautl 2.6 does not work 
correctly
wget https://www.python.org/ftp/python/2.7.6/Python-2.7.6.tar.xz -O 
Python-2.7.6.tar.xz;
xz -d Python-2.7.6.tar.xz;
tar -xvf Python-2.7.6.tar;
(cd Python-2.7.6 && ./configure && make && make install);
ln -s /usr/local/bin/python2.7 /usr/bin/python2.7;
rm -rf /usr/bin/python;
ln -s /usr/local/bin/python2.7 /usr/bin/python;

there is another problem when you install python2.7.6 and you set it like 
default, yum command stops working, so you have to replace teh first line of 
file: /usr/bin/yum with #!/usr/bin/python2.6, to do this you can execute the 
next script.

#Configuring yum module to use python2.6
sed -i "1s/.*/#!\/usr\/bin\/python2.6/" /usr/bin/yum;

So this way python2.6 is used by yum and python2.7.6 is default used by gcloud

Please also not that you can use 

  export CLOUDSDK_PYTHON=/path/to/python2.7

in your .profile or .bashrc file to tell gcloud where to find python.  That's 
probably safer than patching yum...

export CLOUDSDK_PYTHON=/path/to/python2.7

Helped for me. Thanks.
