You have to check which Python you are using. I had the same problem because the Python I was using was not the same one that brew was using. In your command line:
which python
which brew
cd /usr/local/lib/python2.7/site-packages
ls
//you can see PyQt4 and sip are hereusr/local/lib/python2.7/site-packages
to your python path.open ~/.bash_profile
//you will open your bash_profile file in your editor'export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH'
to your bash file and save itpython
import PyQt4
// it is ok nowIt is likely that you are running the python executable from /usr/bin (Apple version) instead of /usr/loca/bin (Brew version)
You can either
a) check your PATH variable
or
b) run brew doctor
or
c) run which python
to check if it is the case.
I solved the same problem for my own program by installing python3-pyqt4
.
I'm not using Python 3 but it still helped.
After brew install pyqt
, you can brew test pyqt
which will use the python you have got in your PATH in oder to do the test (show a Qt window).
For non-brewed Python, you'll have to set your PYTHONPATH as brew info pyqt
will tell.
Sometimes it is necessary to open a new shell or tap in order to use the freshly brewed binaries.
I frequently check these issues by printing the sys.path from inside of python:
python -c "import sys; print(sys.path)"
The $(brew --prefix)/lib/pythonX.Y/site-packages
have to be in the sys.path
in order to be able to import stuff. As said, for brewed python, this is default but for any other python, you will have to set the PYTHONPATH
.
If you're using Anaconda to manage Python on your system, you can install it with:
$ conda install pyqt=4
Omit the =4
to install the most current version.
