KeyError: 'urllib.parse'

[Joseph Tate]

I'm trying to build a onedir exe on windows, but I'm running into
trouble with cherrypy;

Cherrypy has this bit of code:

try:
# Python 3
from urllib.parse import urljoin, urlencode
from urllib.parse import quote, quote_plus
from urllib.request import unquote, urlopen
from urllib.request import parse_http_list, parse_keqv_list
except ImportError:
# Python 2
from urlparse import urljoin
from urllib import urlencode, urlopen
from urllib import quote, quote_plus
from urllib import unquote
from urllib2 import parse_http_list, parse_keqv_list

but my built package fails with this:
...
File iu.py, line 455, in importHook
del sys.modules[fqname]
KeyError: 'urllib.parse'

It's eating up the import error prematurely. Any way to fix this?

I patched the iu.py so that it checks that fqname is in sys.modules before del'ing it and I can get it to build and run now.

Could you please submit your patch?

Thanks in advance.

I had the same problem as Joseph, because url.parse is python 3, I am
using python 2, and some library I use must have a try-catch for the
import like the one in his code.

This mini-patch against the current release (1.5.1) of iu.py seems to
solve the problem, at least getting my program to start (don't see how
to add an attachment in groups interface):

454c454,455
< del sys.modules[fqname]
---
> if fqname in sys.modules:
> del sys.modules[fqname]

Not sure if it creates other problems.

ciao,
Paolo

No need for a patch, this is already fixed in 2.0dev.

Thanks Polo.

It should be fixed in develop branch.

The Python idiom for this is using try/except: "don't ask for permission
but for forgiveness"
