Ok - here goes. I am trying to learn how to use py2app, so I created a simple python file; just hello_world.py
#! /usr/bin/env python
def main():
print "Hello"
if __name__=="__main__":
main()
I followed a tutorial and did the following:
py2applet --make-setup hello.py
python setup.py py2app -A
This created two sub-directories (build and dist), within dist there was a file called hello.app. I attempted to launch it through the GUI but it launched for less than a second and then disappeared. I then went to the CL but simply trying to run it didn't work so I used:
python hello.app
with the following error:
/Library/Frameworks/Python.framework/Versions/2.6/Resources/Python.app/Contents/MacOS/Python: can't find '__main__.py' in 'hello.app'
I've spent all day googling but can't find any tutorials or guides etc. I'm really stuck :-(
I don't know if this helps but this is what is in the setup.py
"""
This is a setup.py script generated by py2applet
Usage:
python setup.py py2app
"""
from setuptools import setup
APP = ['hello.py']
DATA_FILES = []
OPTIONS = {'argv_emulation': True}
setup(
app=APP,
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
)
You have successfully used py2app - it just opens, prints "hello" and then closes really quickly!
If you want to see something, then make it pause for a bit:
print "Hello"
import time
time.sleep(5)
time.sleep pauses a program for the number of seconds given.
You really only want to use py2app with GUI apps, or ones that run in the background.
If you want to run the py2app-built application from the command line, you need to execute the binary inside the application bundle; the bundle itself is not directly executable, so something like this:
dist/hello.app/Contents/MacOS/hello
For scripts that just print to stdout you might try Platypus (though it doesn't do the dependency-packaging stuff of py2app).
It seems that it was working all along - the script was just running so quickly I didn't have a chance to see it. If anyone comes across this go to http://svn.pythonmac.org/py2app/py2app/trunk/doc/index.html and follow the tutorial. Please also read the answers given and the replies I left.

I created a project that follows the example in MutPy's README file.
However, when I run mut.py --target calculator --unit-test test_calculator -m, it just opens mut.py instead of actually running MutPy.
The file has the following content:
#!c:\users\admin\appdata\local\programs\python\python39\python.exe
import sys
from mutpy import commandline
if __name__ == '__main__':
commandline.main(sys.argv)
The README doesn't mention any other configurations that need to be done and says that it should be compatible with Python 3.3+ (I'm on Python 3.9.6).
Is there something I'm doing wrong?
Are you runing this from cmd.exe?
If so try:
python.exe mut.py --target calculator --unit-test test_calculator -m
Note that you need python in your PATH Variable.
It will probably also work if you set python as the default application for .py files.
I have just started writing some simple scripts in python as I've started using ubuntu as my default operating system.
So I came across the code for mpsyt (terminal youtube player). I was surprised how simple the coding was. Could anybody explain what is going on here? I don't undestand how a seemingly complex program could have such a small amount of code....
#!/usr/bin/python3
# EASY-INSTALL-ENTRY-SCRIPT: 'mps-youtube==0.2.5','console_scripts','mpsyt'
__requires__ = 'mps-youtube==0.2.5'
import sys
from pkg_resources import load_entry_point
if __name__ == '__main__':
sys.exit(
load_entry_point('mps-youtube==0.2.5', 'console_scripts', 'mpsyt')()
)
This is an autogenerated stub; it executes an entry point in the mps-youtube package installed in your site-packages. It is not the actual script.
The setuptools project installs such stubs in the bin directory; it's task is to find the right version of the project and load the real script.
There will be a matching lib/python[version]/mps-youtube-0.2.5-py[version].egg-info directory holding metadata, including an entry_points.txt file that contains INI-file-format style information on the package. The load_entry_point('mps-youtube==0.2.5', 'console_scripts', 'mpsyt') line will look for that exact file to load the mpsyt definition from the console_scripts section.
In the [console_scripts] section there will be a mpsyt entry that names the actual module used to run the script. Judging by the project setup.py file that'll look like this:
[console_scripts]
mpsyt = mps_youtube:main.main
pointing to the mps_youtube.main module, where the main() function will be called to do the actual work; look for a lib/python[version]/mps_youtube/main.py file, then search for a def main(): function definition. From Github you can see the actual script is a little longer.
This isn't the entire program. This just runs the rest of the program.
I have a code which I'd like people to be able to use as a stand alone python program, or to import as a module for their own codes. Is there a way to package a module which can also include a program that can be run from the command line?
I.e. from the command-line:
> ZHermesCode
or within ipython or a python script:
import ZHermesCode
Look up Setuptools automatic script creation. For example, python-scss uses this technique to make scss an executable shell command.
In setup.py:
setup(
# ...
entry_points={
'console_scripts': [
'scss = scss.tool:main',
]
},
)
Then defining a function main in scss/tool.py. It also uses the technique mentioned by Loocid to make the tool.py file itself directly executable (as opposed to the wrapper script that is publicly installed by setuptools according to the recipe above):
if __name__ == '__main__':
main()
If you use:
if name == '__main__':
The code held in that 'if' statement will only be ran if someone runs your program from the command line.
If someone was to import your module instead, the code will not run.
Eg
def test(st):
return(st)
if name == "__main__":
print(test("hello"))
If you run this program from the command line, it will print "hello". However, someone could also import this module and have access to the "test" function to use in their own programs.
What I'm trying to do is compile a program I've written in Python 2.7, using pygame, into a standalone app for Mac computers. I'm working on a PC running Windows 8 with no access to a mac, so tweaking the process has been difficult.
When I run the setup file from the command prompt, I get the "text flood" (similar to what py2exe gave me when it worked to compile the windows version) and the program appears to work. It creates build and dist folders, but the dist folder has no contents. When looking at the command prompt output, the last two lines are
BASE_CFLAGS = cfg['CFLAGS']
Key Error: 'CFLAGS'
This seems to happen when py2app is trying to create the application bundle.
Here is the setup.py file I've gotten to thus far:
"""
Script for building the example.
Usage:
python setup.py py2app
"""
from setuptools import setup
NAME = 'PetCute Slide Puzzle Test'
VERSION = '0'
plist = dict(
CFBundleIconFile=NAME,
CFBundleName=NAME,
CFBundleShortVersionString=VERSION,
CFBundleGetInfoString=' '.join([NAME, VERSION]),
CFBundleExecutable=NAME,
CFBundleIdentifier='Py2App and PyGam test',
)
setup(
data_files=['Dog1.jpg', 'Dog2.jpg', 'Dog3.jpg', 'Dog4.jpg', 'Dog5.jp', 'Dog6.jpg', 'Dog7.jpg', 'Dog8.jpg', 'Dog9.jpg', 'Dog10.jpg', 'Dog11.jpg', 'Dog12.jpg', 'Dog13.jpg', 'Dog14.jpg', 'Dog15.jpg', 'Dog16.jpg', 'AYearWithoutRain.ttf'],
app=[
dict(script="PetCute_slidepuzzle.py", plist=plist),
],
setup_requires=["py2app"],
)
The data_files lists out the pictures and text file that need to be bundled with the code. I got to this by adapting the alien.py example. Please let me know if any more info is needed!
It probably had an error during compilation. I suggest you make sure you have Numpy installed, its needed for py2app to compile Pygame programs.
I have a problem with making exe using py2exe. In my project i'm using sqlalchemy with mssql module.
My setup.py script looks like:
from distutils.core import setup
import py2exe
setup(
windows=[{"script" : "pyrmsutil.py"}],
options={"pyrmsutil" : {
"includes": ["sqlalchemy.dialects.mssql", "sqlalchemy"],
"packages": ["sqlalchemy.databases.mssql", "sqlalchemy.cresultproxy"]
}})
But when i'm starting procedure like:
python.exe setup.py py2exe
I'm receiving build log with following errors:
The following modules appear to be missing
['_scproxy', 'pkg_resources', 'sqlalchemy.cprocessors', 'sqlalchemy.cresultproxy']
And in "dist" folder i see my pyrmsutil.exe file, but when i'm running it nothing happens. I mean that executable file starts, but do nothing and ends immediately without any pyrmsutil.exe.log. It's very strange.
Can anybody help me with this error?
I know it's no an answer per se but have you tries pyInstaller? I used to use py2exe and found it tricky to get something truly distributable. pyInstaller requires a little more setup but the docs are good and the result seems better.
For solving this issue you could try searching for the mentioned dlls and placing them in the folder with the exe, or where you build it.
Looks like py2exe can't find sqlalchemy c extensions.
Why not just include the egg in the distribution, put sqlachemy in py2exe's excludes and load the egg on start?
I use this in the start script:
import sys
import path
import pkg_resources
APP_HOME = path.path(sys.executable).parent
SUPPORT = APP_HOME / 'support'
eggs = [egg for egg in SUPPORT.files('*.egg')]
reqs, errs = pkg_resources.working_set.find_plugins(
pkg_resources.Environment(eggs)
)
map(pkg_resources.working_set.add, reqs)
sys.path.extend(SUPPORT.files('*.egg'))
i use Jason Orendorff's path module (http://pypi.python.org/pypi/path.py) but you can easily wipe it out if you want.
