Python Win 3.6.0 x64 issue, missing qt designer ex

Question

I'm a Python newbie and trying to start my first application and am struggling to workout how to use Qt Designer with pyQT5.

I've been using the next command which installs pyqt5.7.1:

pip3 install pyqt5

After the install, I have a

C:\Python36\Lib\site-packages\PyQt5\Qt\bin\Qt5Designer.dll

file but no Qt Designer exe as far as i can tell.

id really appreciate the help if anyone has any idea what i'm missing? Do I have to install the full Qt5 framework to be able to use Qt Designer and pyQT5?

Thanks

Pete

Answer 1

Another way to install QT Designer is as follows:

1. Install latest QT (I'm using 5.8) from QT main site
2. Make sure you include "Qt 5.8 MinGW" component
3. QT Designer will be installed in C:\Qt\5.8\mingw53_32\bin\designer.exe
4. Note that the executable is named "designer.exe"

Answer 2

My solution On Windows

1. pip3 install pyqt5-tools
2. open C:\Users\<userName>\AppData\Local\Programs\Python\Python35-32\Lib\site-packages\pyqt5-tools\designer and copy all the content to C:\Users\<userName>\AppData\Local\Programs\Python\Python35-32\lib\site-packages\PyQt5\Qt\bin, don't overwrite files with the same file name!

Answer 3

On WinPython-64bit-3.5.2.2Qt5 I run:

pip install pyqt5-tools

installs at:

WinPython-64bit-3.5.2.2Qt5\python-3.5.2.amd64\Lib\site-packages\pyqt5-tools\designer.exe

Starts ok!

Answer 4

At some point during the 3.5 version of Python QT Designer was dropped from the pyqt5 package, and then picked up by the pyqt5_tools package. Unfortunately the tools package is not available for Python 3.6 (at least so far).

You can download the version 3.5 32-bit or 64-bit pyqt5_tools package from pypi.python.org:

https://pypi.python.org/pypi/pyqt5-tools/5.7.dev9

Next open the wheel package you downloaded with a zip tool and copy the designer folder and contents to a convenient location. Designer and all the needed dependencies are in this folder. Good luck.
