I have a wxPython/bs4 app that I'm building into an exe with cx_freeze.
There build succeeds with no errors, but trying to run the EXE results a FeatureNotFound error from BeautifulSoup4. It's complaining that I don't have my lxml library installed.
I've since stripped the program down to it's minimal state and still get the error.
Has anyone else had success building a bs4 app with cx_freeze?
Please take a look at the details below and let me know of any ideas you may have.
Thanks,
I've simplified the app to it's most basic state and still get the error. I also get the same error on Python 3.4.
Traceback (most recent call last):

FeatureNotFound: Couldn't find a tree builder with the features you requested: xml. Do you need to install a parser library?
I found some people saying that I need to include lxml and it's dependents in the build script: http://sourceforge.net/p/cx-freeze/mailman/message/27973651/ (sorry for the SF link). I tried this, but still no dice.
Commenting out the line soup = BeautifulSoup("<tag>value</tag>", 'xml') results in no errors.
This file is the simplified app that still gets the error.
# -*- coding: utf-8 -*-
from __future__ import print_function
from bs4 import BeautifulSoup
import wx
soup = BeautifulSoup("<tag>value</tag>", 'xml')
app = wx.App()
frame = wx.Frame(None, wx.ID_ANY, "test frame")
frame.Show()
app.MainLoop()
This is the (simplified) build script I am using.
# -*- coding: utf-8 -*-
from cx_Freeze import setup, Executable
build_exe_opts = {"silent": False, }
base = "Win32GUI"
exes_to_build = [Executable("test.py", base=base),
]
setup(
name="test",
version="0.0.1",
description="FTI test program editor and diff tool.",
options={"build_exe": build_exe_opts},
executables=exes_to_build,
)
I'm not going to include the entire log here, but I did run python build_executables.py build >> C:\temp\build_log.txt so can look for anything that's asked for.
Here are the lines that contain 'lxml' in them:

The build succeeds with no errors.
After much investigation, going into bs4 and their builders, I finally found that I need to also add gzip.
So in the end, the cx_freeze script needs, at minimum, these packages added when building an exe with bs4 + lxml: lxml and gzip.
So your build_executables.py script should look like:
# -*- coding: utf-8 -*-
from cx_Freeze import setup, Executable
build_exe_opts = {"silent": False,
"packages": ['lxml', 'gzip'],
}
base = "Win32GUI"
exes_to_build = [Executable("test.py", base=base)]
setup(
name="test",
version="0.0.1",
description="blah blah blah",
options={"build_exe": build_exe_opts},
executables=exes_to_build,
)
and then when you run python build_executables.py build and try the executable, it should work.
