Description
Environment
- Pythonnet version: 2.3
- Python version: 3.5.0
- Operating System: Windows 10
Details
- I'm trying to install pythonnet on my local machine that has the following packages installed: Python 3.5, pip 9.0.1, setuptools 36.2.7, jsonschema 2.6.0, pytest 3.2.0, and wheel 0.29.0.
- I've tried installing via Nuget, Pip, and from the source code, all with no luck
Nuget installation attempt
-
I created a C# Console Executable Project in Visual Studio 2017 and added the 2.3.0 version of pythonnet to the project via Nuget.
-
I fixed the badimageformatting error by switching CPU configuration to x86
-
I changed the reference for Python.Runtime.DLL to point to /PythonLocation/Lib/site-packages/Python.Runtime.DLL (which I lifted from /VS17App/packages/pythonnet_py35_dotnet2.3.0/lib/net40/Python.Runtime.DLL after the package was installed)
-
When I run the console executable in VS with a simple line of code
using (Py.GIL()) {}, I obtain the following error in VS:
Managed Debugging Assistant 'PInvokeStackImbalance' : 'A call to PInvoke function 'Python.Runtime!Python.Runtime.Runtime::PyImport_ImportModule' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.'
This is the same error referenced in #485 but referencing that runtime DLL does nothing.
Source code installation attempt
I also tried installing from source by cloning the 2.3.0 source into code /PythonLocation/Lib/site-packages/ and running the following command in powershell: python.exe .\setup.py bdist_wheel
This results in the following error stack trace:
running bdist_wheel
running build
running build_ext
Checking for updates from https://www.nuget.org/api/v2/.
Currently running NuGet.exe 4.1.0.
NuGet.exe is up to date.
MSBuild auto-detection: using msbuild version '15.1.1012.6693' from 'C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\bin'.
All packages listed in packages.config are already installed.

Pip installation attempt
I've also tried installing via pip (pip install git+https://github.com/pythonnet/pythonnet -U --force) but that gives the same error as the one mentioned above for the source code.
Summary
I've been stuck on this for days and can't seem to be able to install pythonnet in any way. It seems like it's a C# compiler issue based on my research but I can't seem to figure it out. Any help would be appreciated! Thanks!
