please follow instruction for mac here: You probably need to install from master branch: |
|
I tried installing from master but I got the same error: As for following the instructions in #465, which python points to the anaconda libraries but I can't find clr.so |
|
This is generic python problem. Try to follow this like threads https://stackoverflow.com/questions/14296531/what-does-error-option-single-version-externally-managed-not-recognized-ind |
pip install pip --upgrade
pip install setuptools --upgrade Should solve this issue |

We try to install pythonnet on Linux and upgrading pip and setuptools does not help: $ pip install --upgrade pip setuptools

DEPRECATION: --egg has been deprecated and will be removed in the future. This flag is mutually exclusive with large parts of pip, and actually using it invalidates pip's ability to manage the installation process.

@hjaekel we are tracking this pip+git error in another issue: #555 Thanks for your efforts @hjaekel and @CodeProQuo, please don't forget to star this project! 👍 |
This completely broke my setup: ImportError: cannot import name main |

@phxn please read this thread below and this has nothing to do with pythonnet. But in general I agree that users should work in virtual environment, rather than messing with system python installation: |

Another way to resolve this is to download Windows SDK 10 (latest version). If this alone doesn't work then download Visual Studio 2019 (again whichever is the latest version). This updates the wheel process. |

Try downloading the wheel file from https://pypi.org/project/pythonnet/#modal-close pythonnet downloads. Make sure you download the correct version and use pip install . cp in the file name will give you the python version number it's compatible with. |
I wanted to install a venv for python3.8.2 and Building wheel for pandocfilters and others prdouced erros. Executing your steps and building the venv again solved my issue. |

I face the same error using Python 3.8.8 on Ubuntu 20.04.1 |
