PyQt 4.7 - ImportError After Installing On Windows
Solution 1:
Are you sure there is a \bin
directory for your version of PyQt?
I am running PyQt 4.4, and all my binaries are right in:
C:\Python31\Lib\site-packages\PyQt4
Which is what I have my path pointing too. It sounds like PyQt4 was installed improperly... did you run this?
python setup.py install
There shouldn't be a bin there...
Solution 2:
Just wanted to chime in that I had the same problem on a WinXP install of:
- python 2.7
- Qt 4.7.1 (10.05)
- PyQt 4.8.1
I used the windows installer version of all 3 of those items.
Copying the contents of the C:\Python27\Lib\site-packages\PyQt4\bin folder up to the main PyQt folder (C:\Python27\Lib\site-packages\PyQt4) stopped the 'dll not found' errors that python was throwing.
Solution 3:
Also chiming in. I installed both python 2.6 and PyQt 4.8.3 on a Windows 7 machine using the windows installers (I did NOT run 'python setup.py install').
I tried to run spyder (which requires PyQt 4.4 or greater) and failed because it couldn't find the PyQt .dlls. I copied all the .dlls from the \Lib\site-packages\PyQt4\bin folder to the \Lib\site-packages\PyQt4 folder, and spyder launches just fine.
Solution 4:
PyQt installation also depends on the version of python installed on your platform.Python3.+ is incompatible with Python version < 3.x.
I was facing the same problem as I have Python 2.7 installed on my machine but I downloaded the latest binary which was PyQt-Py3.2-x86-gpl-4.9.exe. If you see here the binary has python version also mentioned in name after PyQt which is Py3.2. I uninstalled PyQt and installed PyQt-Py2.7-x86-gpl-4.9.exe which points to Python 2.7 and it fixed the problem.
Probably they could have mentioned the naming convention online or in some documentation to be more simpler.
Solution 5:
I had the same problem. I got my program running from within Eclipse but when I tried running it directly from the command line I still got the same error.
I solved it by renaming the C:\Users\Me\AppData\Roaming\Python\Python27\site-packages\PyQt4 directory. (I'm guessing leftovers from a previous PyQt install)
I am using ActivePython.
