HI,
I am not sure I should report this as a bug so checking here first if I
am doing something wrong.
The following import fails for me since upgrading to Spyder 2.3.1:
|
fromPyQt4.QtCoreimportQString
"ImportError: cannot import name QString"
|
I upgraded Spyder via Anaconda when they recently released a new version
(which did not update PyQt). I was going to report this problem on their
forum first, but then I tried importing from ipython and ipython
qtconsole when launched directly from terminal and the imports work fine
in these cases.
The Spyder ipython interpreter reports the same version of the Python
and the Qt packages as when I launch ipython/ipython qtconsole from
terminal:
Python 2.7.8 |Anaconda 2.1.0 (64-bit)| (default, Aug 21 2014, 18:22:21)
Type "copyright", "credits" or "license" for more information.
IPython 2.2.0 -- An enhanced Interactive Python.
Anaconda is brought to you by Continuum Analytics.

fromPyQt4.QtCoreimportQT_VERSION_STR
fromPyQt4.QtimportPYQT_VERSION_STR
fromsip importSIP_VERSION_STR
print("Qt version:",QT_VERSION_STR)
print("SIP version:",SIP_VERSION_STR)
print("PyQt version:",PYQT_VERSION_STR)
('Qt version:','4.8.5')
('SIP version:','4.15.5')
('PyQt version:','4.10.4')
|
So I am thinking that Spyder 2.3.1 modifies some setting with the PyQt
libraries as they are imported, but I can't detect which one. Any help
greatly appreciated.
Cheers,
Joel
When using PyQt API v2, QStrings are automatically transformed into
python strings. This is the default in python3. You can change this
setting in the preferences.
