PyInstaller is a program used to convert Python scripts into standalone applications. PyInstaller allows you to run applications written in Python on a computer without requiring the user to install Python. It is an excellent option when you need to distribute a program to the end user as a standalone application. PyInstaller currently only works with Python 2.3 up to 2.7.
PyInstaller claims to be compatible with a lot of third party libraries or packages out of the box. PyQt, Django and matplotlib are fully supported.
To start, download and extract PyInstaller from the official site.

PyInstaller is an application, not a package. So there is no need to install it in your computer. To get started, open a Command Prompt (Windows) or a Terminal (Mac and Linux) and go to the PyInstaller Folder.
Now suppose you want to package myscript.py, I saved it into the pyinstaller folder:
2 | print('Hello World!') |
Then, in order to create the executable just run
python pyinstaller.py myscript.py
and you will see a lot of output and a folder called myscript
will be created, with two folders and a file inside. The build
folder is used by PyInstaller as a temporary folder to create the files needed for the executable. The dist
folder stores the executable and all of the files needed in order to run that executable. It is safe to delete the build folder. The file called myscript.spec
is useful to customize the way PyInstaller packs your application.Now test if your executable works:
Python Create Mac App
2 | myscript |
2 | ./myscript |
You should see now a 'Hello World!' printed on the screen. Monitor app for mac.
Remember that running
python pyinstaller.py myscript.py
assumes that you have Python in your path environment variable. If that is not the case, just use C:Python27python.exe pyinstaller.py myscript.py
in Windows. Most of the time on Linux and Mac OS X, Python will be in your path environment variable.GUI Applications
Now it is time to create a GUI application. In this example we will be using Tkinter:
2 4 6 8 | ''A very basic Tkinter example. '' fromTkinterimport* root.title('A Tk Application') root.mainloop() |
Create Python Application
To pack it, it is mandatory to use the
--windowed
flag, otherwise the application will not start:In this moment you can navigate to the dist folder and run the application by double clicking it.
Note for Mac OS X users: the above example using Tkinter works fine if you use the pre-installed Python version, if you installed or updated Python by yourself, you can find some problems running the packaged application.
Using External Modules
The previous examples were importing modules from the Python Standard Library. PyInstaller includes the Standard Library Modules by default. However if we installed a third party library, PyInstaller is likely not to include it. In most of the cases we need to create 'hooks' to tell PyInstaller to include these modules. An example of this is an application using the ReportLab library to make PDF files:
2 4 6 8 10 12 14 16 18 | fromreportlab.pdfgen importcanvas fromreportlab.lib.units importmm if__name__'__main__': city='Pereira' phone='555-7241' c=canvas.Canvas(filename='invoice.pdf',pagesize=(letter[0],letter[1]/2)) # Print Customer Data c.drawString(107*mm,111*mm,city) c.drawString(107*mm,101*mm,phone) c.save() |
A 'hook' module is a Python file with a special name, used to tell PyInstaller to include a specific module. Doing a Google search i found the needed hooks to pack a ReportLab application here and placed them in a folder named 'hooks':
Reading apps for kids. +- hooks/
|- hook-reportlab.pdfbase._fontdata.py
|- hook-reportlab.pdfbase.py
|- hook-reportlab.py
|- hook-reportlab.pdfbase._fontdata.py
|- hook-reportlab.pdfbase.py
|- hook-reportlab.py
hook-reportlab.py
and hook-reportlab.pdfbase.py
are empty files, hook-reportlab.pdfbase._fontdata.py
contains:2 4 6 8 10 12 14 16 18 20 22 24 | hiddenimports=[ '_fontdata_enc_macroman', '_fontdata_enc_standard', '_fontdata_enc_winansi', '_fontdata_widths_courier', '_fontdata_widths_courierboldoblique', '_fontdata_widths_helvetica', '_fontdata_widths_helveticaboldoblique', '_fontdata_widths_symbol', '_fontdata_widths_timesbolditalic', '_fontdata_widths_timesroman', ] |
Create Mac App From Python Script
Now in order to pack the executable, we have to run
python pyinstaller.py --additional-hooks-dir=hooks/ invoice.py
. The additional-hooks-dir
flag tells PyInstaller to search for hooks in the specified directory.![Mac Mac](https://nundo.fr/wp-content/uploads/2019/10/window-tutorialsteacher.png)
Conclusion
Python App Download
Pyinstaller works great if your script only imports modules from The Python Standard Library, or a module included in the official Supported Packages list. Using these supported packages make packaging applications pretty straightforward, but when wee need to use a third-party not supported module, it can be tricky to make it work. Sparkle web app.
