setup.py build with mono in XUbuntu can't load System.Core (NuGet?) #411
Comments
|
@theresa-anne which build instructions? Our documentation isn't very updated, so it not be correct. |
|
python setup.py build_ext --inplace |
|
try Did the install complete (regardless of which setup.py command you used)? |
|
I don't think so, it exited with a trace report, but I soon discovered that I had exceeded my allocated disk space and had to start over with Virtual Box. Give me some time to try again. |

Brew is only for OSX. Please share your terminal session for full installation steps, e.g. using asciinema. |

Here's the latest attempt:
This time I went to the wiki (could not find "travis.yml") and followed the first step of the Anaconda instructions from the wiki...

Can you install mono-complete? I'm afraid mono-runtime is not enough.

1. Create a new XUbuntu guest in Virtual Box

It seems to be working, but setup is taking an extremely long time to run. I'll follow up late tonight or first thing tomorrow morning to confirm it solved. Thanks for your help! Worked. |

Closing, let us know if you find any issues |

reopening with one last request for feedback. Here's the latest after installing mono-complete: ** I don't recall the mono install asking me for permission to update my PATH.

you are using Mono Version 4.2.1.0 from 2013-2015. Look at installation guide for later mono versions: http://www.mono-project.com/docs/getting-started/install/linux/ alternatively you can try our docker images: |

Environment
Details
I am getting started with Python for .NET in mono on XUbuntu, all 64-bit, in VirtualBox. I installed 64-bit Anaconda2, and unzipped the Python for .NET source materials into the Anaconda bin folder. Note that mono was not built using "brew" (I first discovered that here, and could give it a try). The environment can't load System.Core, and the error report mentions NuGet. I'm a bit of a novice to this community, so I come on bended knee - please feel free to point me to an older thread if necessary. I did search, and did not find what I thought I needed, but things that seem obvious to others may be a learning curve for me. Thanks. - T
from GitHub. Not worried about NPython.exe just yet, just willing to import clr and reference assemblies
as necessary. Any and all help appreciated.
Someone mentioned to me that the OS installs certain Python libraries for its own use and that virtual environments with select libraries are the preferred method. If that's the case, then can someone share their experience with using selected libraries to install Python for .NET, i.e. which libraries you used and which libraries you avoided, if relevant? Thank you so much.
