I have my code written in python 3.6.5. I am trying make this an installable package (something like install shield) and wanted to bundle python software also along with this installshield. OS is Windows
Will python work by unzipping the installation directory and then setting path variable?
When I use /quiet for silent installation of python, I could not change the path of installation directory to my choice, say in my case C:\test(even after setting TargetDir=C:\test). Where am I going wrong?
If there any other approach to bundle installation of python along with installation package can someone let me know?
Why not use Pyinstaller? If python is set to path you can run from CMD pip install pyinstaller. Then you can create a standalone exe that will include the python packages to run. Hold shift and open a CMD where your script is and then run a command similar to this
pyinstaller --noconsole --icon=data.ico --version-file=Version.txt -F LineQuery.py
The -F is the standalone package. Be aware though that you need to copy the DLLs from microsoft runtime visual c++ 2015 into the python DLL folder usually located at C:\Users\"user"\AppData\Local\Programs\Python\Python36\DLLs. That is if you package it on windows 10. Otherwise you'll have issues with your program running on earlier versions of windows.
The standalone package will be slow at startup. You can package it into a folder that will be faster. Just remove the -F

How can I make my GTK3+ Python script work outside of Msys2's own Python interpreter, into my own venv (virtual environment) Python3 interpreter? I want to prepare my Python 3 script for distribution to other computers, but without Msys2.
I'm using Windows 10.
I've successfully followed the instructions on GTK's website, to download GTK3+ and the Python bindings, in Windows.
I've installed GTK3+ and the Python bindings using MSYS2. My script runs successfully within MSYS2's Python3 interpreter in C:\msys64\mingw64\bin. However, I want to run my Python script outside of MSYS2, with a separate Python 3 interpreter (venv) - not the one in MSYS2.
From my research, it seems that I need to copy the GTK3 .dll files and icons from
C:\msys64\mingw64\bin
and C:\msys64\mingw64\share
to the Python3 interpreter path that I want, with my script files in there too.
But when I attempt to run my script in the virtual environment, I get:
builtins.ImportError: cannot import name '_gi' from 'gi'
Any ideas? Thanks.
I don't know if that is possible.
But if the final intent is to distribute your app, then you should install PyInstaller inside MSYS2 and generate an executable there. Then you'll be able to distribute and execute your app on any Windows machine.
It will only be possible to run your program using the MSYS2 Python interpreter and with all of the required libraries. You can't just copy files and then run them with the Windows Python interpreter that was built using MSVC.
PyInstaller is a good solution to package an app with the interpreter and all of the libraries. The issue you mentioned about getting errors about no module named '_struct' has been fixed.
I'm trying to use bluetooth with python, and I came across a module - pybluez. Right then, I tried installing it by running pip install pybluez. The package was located and downloaded, but it raised an error when running python setup.py egg_info.
I then tried to download pyBluez from this link https://pypi.python.org/pypi/PyBluez
But, it said that the Python version installed on my PC is not 2.7 ( I have 2.7.10; do I need 2.7.0 for this?) Also, this download link is for a 32-bit system, and that might be the reason it does not run on mine.
So I ask:
1. How do I fix this error?
Error in the output when I try to install pybluez using pip:
2.Does download using https://pypi.python.org/pypi/PyBluez need python 2.7.0, and a 32-bit system? If so, can someone suggest a better way for a 64-bit system?
3.Any other bluetooth module that could work as a substitute?
I have successfully built pybluez for win10x64 with python3.6
Download and install windows 10 build tools: https://www.visualstudio.com/pl/thank-you-downloading-visual-studio/?sku=BuildTools&rel=15
Run 'Developer Command Prompt for VS' as administrator
Clone pybluez repo https://github.com/karulis/pybluez
cd to directory with repo
run python setup.py install
Happy bluetoothing
This is an "expanded solution" which supplements the other answers posted.
Bluetooth is readily supported on Linux in basically any context. Python 3 built-in socket objects work over bluetooth even. But for Windows, there are hoops to jump through. The standard solution for this is to use PyBluez. If you're really lucky, you might be able to install with just pip install PyBluez-win10. If that fails, however, the way to go is an installation via a pre-compiled "wheel".
A given wheel only works for your specific context, however, i.e. exact Python version. So, for the sake of future proofing, if you are going to need PyBluez, you should know how create a wheel from the source for yourself. It's a long, annoying process if you don't have the all the software required already and are not familiar with some parts of the process e.g. using Anaconda. So, if you are working in a team, I suggest having one person burn their time on this and then share the wheel with everyone (who are hopefully on the same version of Python!).
The following is a paraphrased version of what is posted here: https://github.com/pybluez/pybluez/issues/180 which includes the actual developer's comments and methodology.
Download and run the "Visual Studio Build Tools" installer:
For an official list of exact compilers and links to match against target Python versions, refer to: https://wiki.python.org/moin/WindowsCompilers
Here's the 2019 Build Tools link, which works with Py3.7:
https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2019
During the install you MUST select BOTH "Visual C++ build tools" AND "Universal Windows Platform build tools". Leave the default options alone within those (e.g. including the Windows 10 SDK).
Note: this requires 15GB of disk space, and some patience!
Install "Miniconda":
https://docs.conda.io/en/latest/miniconda.html
Select the one which matches the bit set (32 vs 64) of the destination Python version
you wish to install PyBluez into.
Clone the PyBluez source repo to a temp location (e.g. your desktop). Then, launch the terminal and change into that directory:
git clone https://github.com/pybluez/pybluez
cd pybluez
If you did NOT put conda on the system path (as the installer recommends NOT doing so), you can add it for this local CMD session per this example command:
set CONDA_DIR=%USERPROFILE%\Miniconda3
set PATH=%CONDA_DIR%\condabin;%PATH%
Create a dedicated environment to build pybluez with the desired Python version. Then, launch that. The example below uses Python 3.7 but the same steps will also work for other versions (including Py 2.x etc)
conda create -y -n pybluez python==3.7
activate pybluez
Build a wheel file. Then, leave the dedicated environment.
python setup.py install
python setup.py bdist_wheel
deactivate
Copy the wheel to your desktop. From there, you can do with it as you wish. Then, delete the pybluez conda environment and the source repo, (as you no longer need either of them).
copy .\dist\*.whl "%USERPROFILE%\Desktop"
cd..
rd /s /q "%CONDA_DIR%\envs\pybluez"
rd /s /q pybluez
Finally, you can install the wheel to a target Python instance and/or store/share it:
The name of these files and the path will vary, so define those first for your use case
set PYBLUEZ_WHEEL=%USERPROFILE%\Desktop\PyBluez-0.22-cp37-cp37m-win_amd64.whl
set PYTHON_PATH=python
Install the wheel:
%PYTHON_PATH% -m pip install "%PYBLUEZ_WHEEL%"
Confirm installation:
%PYTHON_PATH% -c "import bluetooth; print(bluetooth.__version__)"
I downloaded a Python 3.6 wheel from here (wheels for python 2.7, 3.5, 3.6, 3.7 available too).
I installed it in my virtual environment via
pip install PyBluez-0.22-cp36-cp36m-win_amd64.whl
One command solution.
pip install git+https://github.com/pybluez/pybluez.git#egg=pybluez
I have created an exe file using cx_freeze (python 3.4).
Along with the exe there is a library.zip,python34.dll and some .pyd file with it.How can i create a standalone exe so that it can be run on other systems where python is not installed.
A single exe file is all i want.Can this be achieved...??
This question was asked previously as well but i didnt find any suitable solutions in it.Help please.
Thanks
At first .pyd files are python native extensions written in either C or C++ for windows target platform. Next in order to get exe built you will going to need to have pyinstaller package installed (http://www.pyinstaller.org/). You can install it using either "pip install pyinstaller", "easy_install pyinstaller" or just specify it as a dependency within REQUIREMENTS.TXT or SETUP.PY of yours. But this package depends on pywin32 package which can only be installed either manually or with easy_install. It doen't support pip because the only bundle that is available is - exe file format. easy_install handles it though.
I need to compile a python script for a project. I am programming it in my Linux(Ubuntu) environment, and I need to have the finalized product be a .exe file to run on windows.
--It needs to be compiled so that the windows machine receiving it doesn't need to have a python environment installed on it.--
I know pyinstaller can compile scripts into executables, but it doesn't do cross-compiling.
An older version of pyinstaller does, but it only supports python2.6
The problem is, I need python 2.7 or 3.+ for my project.
Is there a program I can use to accomplish this, or maybe a workaround... something?
So there is this particular jython project that needs a couple of dependencies, such as Jenkins, some kind of subversion, and this needs to be done on windows.
Would it be sane of me to consider using pip to help install all of these items, or should I look elsewhere, such as NSIS?
Update:
I really should've rephrase this - my fault for asking the question late at night.
There's an automated testing project that has the following dependencies:
Java JDK
Jython
Ant
Robot Framework
subversion
Jenkins
I personally prefer to run on Linux, but people that need to use this are typically Windows users. I'm confident enough to write a script to install all of this on Linux, but what I want is to have a script / installer that would install the relevent tools.
I would prefer to have a single script to do all of this - it's easy on Ubuntu with apt-get; but on windows, this quickly becomes non-trivial.
What is the best way to try and do this? Should I create separate installers for separate OS
pip is the acronym for pip install packages, python packages, and it only install Python packages.
Since Jenkins and Subversion are not Python packages, as far as I know, you can't install them, and it is not "sane".
Unfortunately there is no single established tool to install everything in every platform.
Use pip to install all your python packages, and prefer to use virtualenv to create isolated Python environments to manage your projects.
Since pip only installs python packages and Jenkins isn't a python package (it's written in Java), you cannot use it to install those packages.
You should totally take a look to virtualenv, but if you need to do a "double click" installer for your project in Windows i think that NSIS is the way to go.
I am successfully using install4j to create an executable installer for Windows, Linux and OSX. The application is Java and it bundles JRE. Install4j creates installer for each specified platform using respective JRE. So far it worked great on Windows and it somewhat works on Linux and OSX (e.g. in new version of install4j, JRE for Java 1.8 is not bundled properly for linu, so the JRE is preinstalled, but it could be automated). It also allows you to run non-interactive installer.
