I'm sure there's a really simple solution to this, but I'm still fairly new to Python.
I'm trying to use dateutil.parser.parse() to parse a string with a timestamp in it:
>>> import dateutil.parser
>>> a = dateutil.parser.parse("2011-10-01 12:00:00+01:00")
>>> print a
2011-10-01 12:00:00+01:00
This works fine on my Linux server, but on my Windows test box it gives an error:
>>> import dateutil.parser
>>> a = dateutil.parser.parse("2011-10-01 12:00:00+01:00")
Traceback (most recent call last):

TypeError: initial_value must be unicode or None, not str
If I try giving dateutil.parser.parse() a unicode string, that doesn't work on the Windows box either:
>>> a = dateutil.parser.parse(unicode("2011-10-01 12:00:00+01:00"))

TypeError: iter() returned non-iterator of type '_timelex'
Yet this also works on the Linux box.
It's not a Windows issue, it's Python version / library version issue.
dateutil 2.0 is written to support only Python 3, not Python 2.X. Both cases here contain bugs when used with Python 2.X.
In the first case:
dateutil.parser.parse("2011-10-01 12:00:00+01:00")
the io.StringIO
class allows only unicode arguments, but the code reads:
if isinstance(instream, str):
instream = StringIO(instream)
In the second case:
dateutil.parser.parse(unicode("2011-10-01 12:00:00+01:00"))
if you look at _timelex
class, it contains the __next__
method, which is Python3's way of indicating that an object supports iteration protocol. In Python 2.X, the name of the method should be next
.
Check if you have the same versions of both Python and the library on Linux and Windows. From project website:
