cx_freeze fails to create exe with pandas library

问题:

Having problems creating exe using cx_freeze with a Pandas library. I have seen lots of others having issues with numPy but I was able to successfully bring in numPy. My big pain point has been Pandas. Is there anything in Pandas that might be causing to fail?

Setup file

from cx_Freeze import setup, Executable
build_exe_options = {
"includes": ['numpy', 'pandas'],
"packages": [],
'excludes' : [],
"include_files": []}

setup(
    name = "appName",
    version = "0.1",
    description = "",
    author = "Dengar",
    options = {"build_exe": build_exe_options},
    executables = [Executable("appName.py")]
    )

Code snippet showing what I am pulling in

import pyodbc
import numpy as np
import pandas.io.sql as psql
from pandas import  DataFrame, Series, date_range
import datetime

print("Hello World")

Here is the Error log I get

If I remove Pandas from my Setup file and snippet and leave Numpy I have a functional executable. Anybody run into this issue? The exe gets created but none of the supporting files is added to the build directory. On open of the exe, I the program immediately crashes.

I am running python27 64 bit on anaconda windows 8 machine.

Add the following to your build_exe_options:

'build_exe': {
    'excludes': ['boto.compat.sys',
                 'boto.compat._sre',
                 'boto.compat._json',
                 'boto.compat._locale',
                 'boto.compat._struct',
                 'boto.compat.array'],
}

I looked at boto/compat.py and did not see a sys module being imported. By excluding the above list of modules, boto/compat.py is still included.

After excluding 'boto.compat.sys' and 'boto.compat._sre', I got the following error:

Traceback (most recent call last):
  File "setup.py", line 31, in <module>

    path = os.pathsep.join([origPath] + module.parent.path)
TypeError: can only concatenate list (not "NoneType") to list

I ran ipython and then typed:

In [1]: pdb
Automatic pdb calling has been turned ON

In [2]: run setup.py build

To get access to module from module.parent.path:

ipdb> module
<Module name='boto.compat._json', file='/Users/king/virtual_envs/py27/lib/python2.7/lib-dynload/_json.so'>

NOTE: _json.so is the built in json module. This means putting it in the includes specifically should include it. I did not since other packages caused cx_freeze to pick it up automatically. Excluding 'boto.compat._json' did the trick.

I repeated this until I the whole thing built. I confirmed all base modules were picked up by cx_freeze (_sre, _json, _locale, _struct, array) so I did not need to add them manually to includes.

So, your updated script will look like:

from cx_Freeze import setup, Executable
build_exe_options = {
"includes": ['numpy', 'pandas'],
"packages": [],
'excludes' : ['boto.compat.sys',
              'boto.compat._sre',
              'boto.compat._json',
              'boto.compat._locale',
              'boto.compat._struct',
              'boto.compat.array'],
"include_files": []}

setup(
    name = "appName",
    version = "0.1",
    description = "",
    author = "Dengar",
    options = {"build_exe": build_exe_options},
    executables = [Executable("appName.py")]
)

The following should help you get over this problem (and may lead you to the next one of missing dependencies ;) )

Checking the code for freeze.py, there is a case that is not checked, so I made the following changes to freezer.py:

line 600, from

    try:
        if module.parent is not None:
            path = os.pathsep.join([origPath] + module.parent.path)
            os.environ["PATH"] = path
        self._CopyFile(module.file, target, copyDependentFiles)
    finally:
        os.environ["PATH"] = origPath

to:

    try:
        if module.parent is not None:
            if module.parent.path is not None:
                path = os.pathsep.join([origPath] + module.parent.path)
                os.environ["PATH"] = path
                self._CopyFile(module.file, target, copyDependentFiles)
            else:
                path = os.pathsep.join([origPath, os.path.dirname(module.parent.file)])
                os.environ["PATH"] = path
                print '========================================================'
    finally:
        os.environ["PATH"] = origPath
