PyInstaller executable issue

[ardoramor]

After testing the application to work from source, I've built an executable:
pyinstaller.exe --onefile app.py

When I run the app.exe from the cmd, it prints the following error to the log:

Traceback (most recent call last):
File "", line 146, in
File "C:...\build\app\out00-PYZ.pyz\gooey.python_bindings.gooey_decorator", line 86, in inner
IOError: [Errno 2] No such file or directory: 'C:\Users...\AppData\Local\Temp_MEI108682\gooey_tmp\app.exe'

Does Gooey play well with PyInstaller or it hasn't been tested?

[chriskiehl]

You're a bit of a pioneer :) I haven't dug into PyInstaller and what all Gooey needs in order to be packaged up nicely.

Try running it without --onefile. I know in the past there was an issue with PyInstaller that, for whatever reason, would cause it to throw an error whenever you packaged a python app that used multiprocessing with --onefile. I dunno if that's still the case, but it could be a good starting point for debugging.

(note: typing this at work.. so it's just a quick off the top of my head guess at one possible issue)

I'll hopefully dig into the issue soon.

I got the following output while compiling without --onefile:

Traceback (most recent call last):
File "", line 151, in
File "C:\Users...\Documents\Projects\app\build\App\out00-PYZ.pyz\gooey.python_bindings.gooey_decorator", line 86, in inner
IOError: [Errno 2] No such file or directory: 'C:\Users...\DOCUME1\PROJ1\Ap1\dist\Ap1\gooey_tmp\App.exe'

The following directory exists:
'C:\Users...\DOCUME1\PROJ1\Ap1\dist\Ap1
But gooey_tmp\App.exe does not exist.

Looking at PyInstaller's warning output, I noticed the following:
W: delayed import hack detected at line 0 - gooey.python_bindings.modules (C:\Python27\lib\site-packages\gooey-0.1.0-py2.7.egg\gooey\python_bindings\modules.pyc)

I can confirm this error as well, with perhaps a bit more traceback:

Traceback (most recent call last):
  File "<string>", line 24, in <module>
  File "Z:\...\build\build\test\out00-PYZ.pyz\gooey.python_bindings.gooey_decorator", line 96, in inner

using the compile options

wine python pyinstaller/pyinstaller.py --hidden-import=gooey test.py

and the test file

import gooey
from gooey import GooeyParser

@gooey.Gooey()
def main():
    parser = GooeyParser()
    parser.add_argument('-i', widget='FileChooser')
    args = parser.parse_args()
    print "DONE"



if __name__ == '__main__':
  main()

So, I tried messing around and compiling gooey. It did not work out but since there is an open issue i'll try to add in what i have.

I got passed the part where it complains about the language files (Thank you .spec file), with these files :

My test.py File

from gooey import Gooey
from gooey import GooeyParser
import argparse

@Gooey
def toto():
    parser = GooeyParser()
    parser.add_argument("toto")
    print("After add_argument")
    parser.parse_args()
toto()
print("Hello World!")

My test.spec File : (As a --onefile)

# -*- mode: python -*-
#Gooey_languages and gooey_images are used to fetch the files and solve the problem that was occuring preivously. (i.e : Language file not found)
gooey_languages = Tree('C:/Python27/Lib/site-packages/gooey/languages', prefix = 'gooey/languages')
gooey_images = Tree('C:/Python27/Lib/site-packages/gooey/images', prefix = 'gooey/images')
a = Analysis(['test.py'],
             pathex=['c:\\Python27\\Scripts'],
             hiddenimports=[],
             hookspath=None,
             runtime_hooks=None)
pyz = PYZ(a.pure)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          gooey_languages, # Add them in to collected files
          gooey_images, # Same here.
          name='test.exe',
          debug=False,
          strip=None,
          upx=True,
          console=True )

Commandline :
pyinstaller test.spec

Some warnings pop up, however since no reference to import issues are made when launched, i'm assuming they're uneventful.

C:\Python27\lib\site-packages\PyInstaller\hooks\hook-wx.lib.pubsub.core.py:11: RuntimeWarning: Parent module 'PyInstaller.hooks.hook-wx.lib.pubsub' not found while handling absolute import
  import os
C:\Python27\lib\site-packages\PyInstaller\hooks\hook-wx.lib.pubsub.core.py:12: RuntimeWarning: Parent module 'PyInstaller.hooks.hook-wx.lib.pubsub' not found while handling absolute import
  import PyInstaller.hooks.hookutils
C:\Python27\lib\site-packages\PyInstaller\hooks\hook-wx.lib.pubsub.core.py:14: RuntimeWarning: Parent module 'PyInstaller.hooks.hook-wx.lib.pubsub' not found while handling absolute import
  from PyInstaller.hooks.hookutils import logger

And it outputs an executable. Yay! However when launched, it displays a Gooey window, allows you to enter the arguments, but once you hit start it outputs an error that always sticks to these lines :

File "c:\.....\appdata\temp\tmp_xxxxx.py", line 1
SyntaxError : Non-ASCII character '\x90' in file
c:\......\tmp_xxxxx,py on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details.

So on I go to see what this says. And it is due to python believing all files are encoded in ascii since nothing else was specified. Very well. I meddled with site.py to set the default encoding to utf-8 and see if that would help. It did not. (Printing sys.getdefaultencoding() returns utf-8 so i know it has been set and that the character in question is among the utf-8 set.)
As for adding the # -*- encoding : utf-8 -*- to every file (gooey and all included) i didn't have the courage so i do not know if it could help.

As far as trying to do a directory build (and not a --onefile which is wht my spec file does) I could not figure out a way to bypass "missing python27.dll". Adding it to binaries did not work, it is present in both sys directories (32 and 64) so i must be doing something wrong on that side and thus cannot really test it that way.

But if the people who can manage a clean build without --onefile could throw in the lines that i added to fetch the language/image packs in the .spec file, it might solve the problem noted by @thoppe

[daranguiz]

@Roshgar, found the issue!

In gooey\python_bindings\config_generator.py, change:

run_cmd = 'python {}'.format(source_path)

to

if hasattr(sys, 'frozen'):
    run_cmd = source_path
else:
    run_cmd = 'python {}'.format(source_path)

Gooey is trying to launch your file as if it were a python file, ie python myfile.exe, leading to the weird encoding issues. Just tell it to launch as-is instead of prepending python, and it works great.

[8BitAce]

Combining the solutions by @Roshgar and @daranguiz works great for me.

@daranguiz: Will you be creating a PR for this fix? I can do so instead if it's easier.

I'm also going to try to take a look at helping PyInstaller work out of the box with Gooey. They seem like a perfect combination.

[daranguiz]

@8BitAce: It'd be easier for me if you submitted the PR, thank you!

[iodbh]

I also have the issue where the language file are not found at runtime - @Roshgar 's method of editing the spec file does not help. The only difference I can see is that I'm using Linux, but I've adjusted the paths accordingly.

[chriskiehl]

@iodbh There's a pull request by @Shura1oplot here ( #118) that says it has fixes for the numerous path issues. Do you wanna check out that branch and see if it fixes your problem?

[iodbh]

Done. The fix works if I copy the languages and images directories into dist/gooey; but the files are not found if I add them to pyInstaller's collect files (via @Roshgar 's edits in the spec file). The new error message is more explicit :

IOError: cannot locate Gooey resources. It seems that the program was frozen, but resource files were not copied to directory of the executable file. Please copy `languages` and `images` folders from gooey module directory into `/home/user/projects/gooeytest/dist/gooey/` directory.

So the generated executable is now runnable if the directories are copied.

[tandreas]

I had this same issue as @iodbh today, @Roshgar's method was not working with the latest version 0.8.14.0. Unfortunately copying the directories dist/gooey directory is not an option when using PyInstaller onefile.

I downgraded to 0.8.12.0 and it started working again. This is on Windows.

@tandreas : (

Arg... Alright, next task at the top of my TODO is to solve all these packaging woes!
