Install wxPython 2.8 (For Ride) on OSX “El Capitan”

Question

I\'m trying to install wxPython 2.8 unicode version, to be able to use robotframework-ride.

So far the installer downloaded from the site failed with an error saying \"T

I ran into the same error:

$ sudo installer -pkg /Volumes/wxPython2.9-osx-2.9.5.0-cocoa-py2.7/wxPython2.9-osx-cocoa-py2.7.pkg/ -target /

installer: The install failed (The Installer could not install the software because there was no software found to install.)

As you may know, on OS X, RIDE supports both wxPython 2.8 and 2.9, and that's why I'm using v2.9 here:

try:
    import wxversion
    from wxversion import VersionError
    if sys.platform == 'darwin': # CAN NOT IMPORT IS_MAC AS THERE IS A wx IMPORT
        wxversion.select(['2.8', '2.9'])
    else:
        wxversion.select('2.8')
except ImportError:
    print "wxPython not found."

Although wxmac formula can be used to install wxPython 2.9.5.0, but on OS X 10.11 El Capitan, you'll encounter the following error reported in #16329 while building wxWidgets.

So, we have to build it from (modified) source code:

1. Install Xcode, and download wxPython-src-2.9.5.0.tar.bz2.

2. Extract the tarball and replace #include (in src/osx/webview_webkit.mm) with #include .

Then follow the instructions described in wxmac formula to build and install wxPython:

$ cd wxPython-src-2.9.5.0
$ PREFIX=/usr/local
$ ./configure --prefix=$PREFIX --enable-shared --enable-monolithic --enable-unicode --enable-std_string --enable-display --with-opengl --with-osx_cocoa --with-libjpeg --with-libtiff --with-libpng --with-zlib --enable-dnd --enable-clipboard --enable-webkit --enable-svg --with-expat --with-macosx-version-min=10.11 --enable-universal_binary=i386,x86_64 --disable-precomp-headers
$ sudo make install

$ cd wxPython
$ sudo python setup.py build_ext WXPORT=osx_cocoa WX_CONFIG=$PREFIX/bin/wx-config UNICODE=1 INSTALL_MULTIVERSION=1 BUILD_GLCANVAS=1 BUILD_GIZMOS=1 BUILD_STC=1

$ sudo python setup.py install WXPORT=osx_cocoa WX_CONFIG=$PREFIX/bin/wx-config UNICODE=1 INSTALL_MULTIVERSION=1 BUILD_GLCANVAS=1 BUILD_GIZMOS=1 BUILD_STC=1

To verify the installation:

$ python
>>> import wx
>>>

Note that this is a 64-bit setup, you don't have to run RIDE in 32-bit mode.
