fabric error

problem
#1

Hello, trying to build from source code, i end up with the following error:

File “/usr/lib/python2.6/site-packages/Fabric-1.8.2-py2.6.egg/fabric/main.py”,
line 658, in main
docstring, callables, default = load_fabfile(fabfile)
File “/usr/lib/python2.6/site-packages/Fabric-1.8.2-py2.6.egg/fabric/main.py”,
line 165, in load_fabfile
imported = importer(os.path.splitext(fabfile)[0])
File “/mydir/fabfile.py”, line 505
with cd(env.VENDOR_PATH), settings(warn_only=True):
^
SyntaxError: invalid syntax

i’m centos 6.4 default pyton version is 2.6.6

An idea?
Regards

That code requires Python 2.7.

Perhaps you can import from __future__ to get ‘with’.

#4

It’s actually the multiple-argument ‘with’ that was added in 2.7; you could change it to “with cd(…): with settings(…):” but I imagine you have some other 2.7-isms in NewsBlur, which is why I suggested just getting a newer version…

Well thank you guys for your help, Nicholas i’ve change my python version to 2.7, and you were right, that removed the splitext error, however i have a new error importing boto connection:

File “/usr/local/lib/python2.7/site-packages/fabric/main.py”, line 658, in mai
n
docstring, callables, default = load_fabfile(fabfile)
File “/usr/local/lib/python2.7/site-packages/fabric/main.py”, line 165, in loa
d_fabfile
imported = importer(os.path.splitext(fabfile)[0])
File “/newsapps/fabfile.py”, line 5, in
from boto.s3.connection import S3Connection
ImportError: No module named boto.s3.connection

I’m sure i have boto installed:

Setting up Install Process
Package python-boto-2.25.0-2.el6.noarch already installed and latest version
Nothing to do

I know that this is may not be the correct place to ask about this issue, i’m googling around linux forums, but appreciate if you can help me.

Thank you guys

That package is a version of boto for Python 2.6. You might try either (a) a distribution that has Python 2.7 as its default Python, or (b) using native Python packaging, i.e., pip, instead of RPMs.

#7

well thank you again Nicholas, pip -intsall -U boto fixed that

but now i’m stuck on other issues, here is my out:

fab -H localhost setup_all

is their any guide for walking through fabfile for linux installation?

thanks again

You’ll want to find a “newsblur secrets skeleton” and place that in /srv/secrets-newsblur

thank you Samuel, but where can i find that :slight_smile: ?
If i succeeded with building from source, i will write a full guide about the process.
