I am using cx_Freeze to convert Python scripts to Windows executable. I am using cxfreeze script present in the Scripts directory. I want the executable generated by cxfreeze to be in a different directory and the .dll's and .pyd's in a different one. When I tried to put the two of them in separate directories the .exe did not work I got
The application has failed to start because python33.dll was not found. Try reinstalling to fix this problem
I know this happends because the executable and (dll's & .pyd's) are located in different directories. Is there a way to keep them in different directories ?
I am using the following command to generate the executable
C:\Python33\Scripts>cxfreeze C:\Users\me\Desktop\setup.py --target-name=setup.exe --target-dir=C:\Users\me\Desktop\new_dir
Python for Windows really requires that the main pythonXX.dll (in this case, python33.dll) exists in C:\windows\system32\
In all of our various combinations of installing Python to different locations, network drives, etc. we've always had to use a little batch file to copy pythonXX.dll into the system32 dir.
I don't think PATH manipulation will work for you, just try copying the dll to system32 and see if your issues go away.
Then again, if you installed another version of Python to say C:\Python33 , then that windows-based installer will do this for you, and you'll be able to run your other Python location.

I don't know if my question is ambiguous or not but, I noticed that in Scripts folder inside the python installation folder there are executable files. Each file about a 100kb in size.
FYI: when I open it (or them) using 7Zip I often find a init.py file inside.
Thanks
I have tried researching but can't seem to find the answer.
The setuptools package builder is able to
Automatically generate wrapper scripts or Windows (console and GUI) .exe files for any number of “main” functions in your project. (Note: this is not a py2exe replacement; the .exe files rely on the local Python installation.)
(ref. from setuptools documentation)
Unfortunately the way it is actually done is considered an implementation detail and is not documented.
I have finished my python project and now want to transfer the project into one file, so a user can just double click it and doesn't have to compile it first.
Therefore, I wanted to know if this is possible with python.
I 've read that you can convert a single python script into an executable file using pyinstaller. But in my case I have many files in different folders and I want them to be include in the executable file because otherwise the programm doesnt work.
I also tried this via the auto-pyto-exe converter (https://github.com/brentvollebregt/auto-py-to-exe) but I didnt got the results I wanted.
Therefore, my question is, how can I convert my visual studio python-project with many different files and folders into one executable file, so a user can just double click the file to start it?
Edit
In the other folder are also .py files like some FileImport.py or View.py. I separated these files that the whole project looks cleaner.
The Folder structure looks as follows:
-Views
---MainView
---UpdateView
---AnotherView
-Controllers
---MainViewController
---UpdateViewController
-Model
---MainModel
I found the solution. As it appears the pyinstaller can find all dependencies when you compile your script via pyinstaller myscript.py. PyInstaller creates three different folders where all necessary files are located. In the dist folder one executable is located which can be used from computers without python installed.
I hope this helps somebody who has the same problem.
I'm trying to run pyinstaller in python exe file in order to someone without python can use pyinstaller but no idea how to do it.
I tried import PyInstaller with other needed modules and convert this script to exe but I got error "The 'PyInstaller' distribution was not found and is required by the application". I also tried to pack PyInstaller exe file but didn't worked too. Python 3.6.5
Any ideas how to do it?
Unfortunately, what you're describing is not possible with PyInstaller. I submitted an issue on GitHub, and this is what one of the developers said:
Nope, this won't work.
PyInstaller internally uses a lot of sub-processes where it is assumed that sys.executable points to a python interpreter (e.g., here); this is not true in a frozen application, where it points to the frozen executable, which ends up in effectively endless recursion.
Even if this was not a problem, the frozen application includes only a subset of python environment, so it cannot be used to freeze an arbitrary script (not to mention the issue of 3rd party packages).
So whatever use case you have for this, it cannot be supported by PyInstaller.
check the requirements for the Pyinstaller from this link initially
https://pythonhosted.org/PyInstaller/requirements.html
Then install Pyinstaller by,
pip install pyinstaller
To create .exe file use this command for basically,
pyinstaller your_script.py
To run the created .exe
METHOD 1
Do double click the .exe file in your directory.
METHOD 2
In your cmd prompt load in to your current directory or project directory then do
: .\dist\your_script.exe
because the create .exe files are saved in dist folder inside to the project folder with the name of your script file names only.
I am struggling a lot trying to create a .exe for my Gui originaly coded with opensuse. I am trying to make the .exe for windows (under XP). cx_freeze seems to work better for my case. The build folder is created properly but when I try to run .exe I have the following error :
"proj data directory not found. Expecting it at C:\Python\build\exe.win32-2.7\library.zip\mpl_toolkits\basemap\data "
So do you know how I could do my setup.py in order to copy the folder mpl_toolkits\basemap\data to library.zip?
Here I posted my working solution for the same issue: https://stackoverflow.com/a/26519937/2741329
My fix requires 2 changes:
- Adding the files to include in the cx_freeze setup script
- Adding an OS environment variable in the user script
A similar issue with the same fix was also adressed here by simply adding in the setup file a list of tuple for include_files as [("C:\\Python31\\Lib\\site-packages\\PyQt4\\mpl-data", "mpl-data")]
This is not enough for Basemap since cx_freeze put by default its scripts into a zipped file.
I've been searching through SO for a while now trying to come up with an answer to this but due to my inexperience with programming I don't understand much of the documentation, nor am I confident enough to experiment too much.
Would anyone be able to describe in slightly simpler terms how I would use programs like Py2exe, PyInstaller, cx_freeze etc.? I just want a way for others (mainly friends) to be able to run my (simple, text only) program without having to download python themselves. If there is an easier way to do this I'd appreciate knowing that too.

There are two distinct ways of freezing python scripts to create executables:
Packing the interpreter and *.pyc files into one exe file-container. Such an approach is used by tools like PyInstaller, Py2exe, cx_freeze.
Creating native code from Python source, usually using a middle step of converting Python-source to C or C++ code. This is done by such tools as Shed-skin and Nuitka. The problem of this aproach is that such tools do not always support all the functionality of Python (e.g. they can have some typing limitations and so on)
The point where you have to start is reading the documentation. Such tools are not just push-and-run style tools, they usually have some configuration that must be implemented (that's the problem of possibly all build systems, and as the project grows, the configuration and number of hooks also grows).
You can start with Py2exe tutorial and 'hello-world' to get acquainted with that how compilation is done. As far as I know it's a simplest way to get your goal.
And the last thing, you can't create cross-platform native executables as their file formats are strongly operating system and hardware dependent.
Download py2exe
Download this msvcp90.dll
Copy your FileCode.py AND msvcp90.dll to C:\Python27\
In C:\Python27\ create new text file, then enter this code inside it:
from distutils.core import setup
import py2exe
setup(console=['Avril.py'])
Replace Avril.py with YourFileName.py
Save the file as setup.txt
Open CMD and type this:
cd C:\Python27\
python setup.txt py2exe
Now go to C:\Python27\dist\ and there's your .exe program.

Python scripts can be made directly executable, like shell scripts, by putting the python environment path in the top of the script file.
#!/usr/bin/env python3.5
The Python installer automatically associates .py files with python.exe so that a double-click on a Python file will run it as a script. The extension can also be .pyw, in that case, the console window that normally appears is suppressed.
Detailed description also for linux is here.
Install pyinstaller, a program that converts .py to .exe for python 2.7 to where python is located:
cd C:\python27\scripts
pip install pyinstaller
then move whatever python file you want to compile to C:\python27\scripts, compile from there by using:
pyinstaller --onefile yourfile.py
the --onefile is optional but it packages the whole thing(in this example yourfile.py) into one .exe. Once everything is done there will be 2 new folders along with a .spec file. From C:\python27\scripts open the folder dist. Your .exe will be located there in one file which you can double tap to execute and distribute to anyone who doesn't have python. Hope it helps.
