https://duan.ca/tag/pyqt5/ <p>Today I installed PyQt5 on OS X 10.9. Turns out, it's not as straight-forward as one would think.</p> <p>Using <code>homebrew</code> will <strong>not</strong> work:</p> <pre><code> brew install PyQt5 --with-python3 </code></pre> <p>This is because of <a href="https://github.com/Homebrew/homebrew/issues/25735">an unfortunate choice</a> made by the homebrew maintainer regarding Python 3.</p> <p>So installing from <a href="http://pyqt.sourceforge.net/Docs/PyQt5/installation.html">source</a> is the way to go. Following the installing instruction, you would download and install <a href="https://web.archive.org/web/20140410074945/http://pyqt.sourceforge.net/Docs/sip4/installation.html">sip</a> first, the install <a href="http://pyqt.sourceforge.net/Docs/PyQt5/installation.html">PyQt5</a> itself.</p> <p>Except that's not enough. When you run <code>python configure.py</code>, you see this error:</p> <pre><code> error: Use the --qmake argument to explicitly specify a working Qt qmake. </code></pre> <p>It's pretty self-explanatory. <code>qmake</code>, the build tool for qt is needed here. Install qt5 with homebrew and proceed:</p> <pre><code> brew install qt5 </code></pre> <p>Afterwards, you should be able to import <code>PyQt5</code> in a Python 3 REPL.</p> Wed, 23 Apr 2014 10:36:00 -0600 https://duan.ca/2014/04/23/installing-pyqt5-with-python-3-on-os-x/ https://duan.ca/2014/04/23/installing-pyqt5-with-python-3-on-os-x/
