Error after installing WinPython

2017-03-19T17:08:04.108000Z

Hello everyone, I have problem after installing WinPython. I can't open Spyder, Qt..etc.

OS: Win10 64Bit
WinPython: 3.5.2.3

Add packages moviepy and sounddevice

2016-11-15T15:12:40.667000Z

It would be great to include moviepy and sounddevice pacakages. They are the most practical ones I have seen so far, especially very useful for people working in video and audio signal processing fields.

or maybe rather:
SOURCE_PATTERN = r'([a-zA-Z0-9-_.])-([0-9._][a-z][-]?[0-9])(.zip|.tar.gz|-(py[2-7]|py[2-7].py[2-7]*)-none-any.whl)'

ah, ok, in your python-2.7.10.amd64\Lib\site-packages\winpython\utils.py , at line 466

try to replace
SOURCE_PATTERN = r'([a-zA-Z0-9-_.])-([0-9._][a-z][0-9]?)(.zip|.tar.gz|-(py[2-7]|py[2-7].py[2-7])-none-any.whl)'

per
SOURCE_PATTERN = r'([a-zA-Z0-9-_.])-([0-9._][a-z][0-9])(.zip|.tar.gz|-(py[2-7]|py[2-7].py[2-7]*)-none-any.whl)'

Ok, I could figure out it.

The reason the list stays empty is an exception in wppm.get_installed_packages(), line 358:
# create pip package list
wppip = [Package('%s-%s-py2.py3-none-any.whl' %
(i[0].lower(), i[1])) for i in pip_list]
for the input parameter pyosc-0.3.5b5294-py2.py3-none-any.whl of Package class.

The exception is thrown from wppm.Package.extract_infos(), line 155:
elif bname.endswith(('.zip', '.tar.gz', '.whl')):
# distutils sdist
infos = utils.get_source_package_infos(bname)
if infos is not None:
self.name, self.version = infos
return
raise NotImplementedError("Not supported package type %s" % bname)
because infos for bname=pyosc-0.3.5b5294-py2.py3-none-any.whl is None

This in turn caused by the fact that the regular expression utils.SOURCE_PATTERN does not match the given bname, the match will be None:
def get_source_package_infos(fname):
"""Return a tuple (name, version) of the Python source package"""
match = re.match(SOURCE_PATTERN, osp.basename(fname))
if match is not None:
return match.groups()[:2]

WinPython relies on pip list for the informations, so I expected a failure is happening because of this strange packaging name. I don't see why.
The code that get the list is:

import imp, pip
pip.utils.pkg_resources = imp.reload(pip.utils.pkg_resources)
pip_list = [(i.key, i.version) for i in pip.get_installed_distributions()]
print (pip_list)

can you try it and paste the result here ?

Ok, after some inverstigation more facts on the issue:

Note the package file has name pyOSC-0.3.5b-5294.tar.gz (with a '-' sign within version number) so dragging this one onto WinPython Control Panel <Install Upgrade="" Packages=""> tab shows:
Action: Install Name: pyOSC-0.3.5b Version: 5294 (already wrong, Ok malformed package name :)
After installation in Lib\site-packages appears a folder pyOSC-0.3.5b5294.dist-info (without '-' sign between '5b' and '5294')
If I understand correctly when the Control Panel updates 'Uninstalled Packages' list it reads all 'dist-info' directories in Lib\site-packages and some-how the parsing of the pyOSC version "0.3.5b5294" fails and the list stays uninitialized ?

you may try the "pip list" command to see how it works with this package installed. Eventually post the result here.
