AttributeError: 'CalledProcessError' object has no attribute 'output'

Question

...using AutoKey 0.81.4 on Ubuntu 10.04

1. relatively new to Linux (<1yr)
2. This is the first python I've written

the following script for AutoKey keeps failing with the following error. What am I not getting here??

Script name: 'find files script'
Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/autokey/service.py", line 442, in execute
    exec script.code in self.scope
  File "<string>", line 13, in <module>
AttributeError: 'CalledProcessError' object has no attribute 'output'

The script

import time

time.sleep(0.10)
retCode, args =  dialog.input_dialog("Files to Find","enter a file name")
fmt = "find / -name \"{0}\" -type f -print 2>/dev/null "
if retCode == 0:
    if len(args) > 0:
        cmd = fmt.format(args)
        #dialog.info_dialog(title="the command",message=cmd)
        try:
            rc = system.exec_command(cmd, getOutput=True)
        except subprocess.CalledProcessError, e:
            dialog.info_dialog(title="the return",message=str(e.output))

Answer 1

Change the e.output to just e. Using str(e) will get you the error string. You may want to look up exceptions to find out what attributes they support. I don't think output is one of them.

Answer 2

The output attribute doesn't exist until Python 2.6. You could use subprocess.Popen and communicate(). Or you could backport subprocess.check_output (also not in 2.6) following this.
