问题
I would like to install pythonnet on Ubuntu, but it fails.
That's what I tried so far:
/usr/bin/python3 -m pip install -U pythonnet --user
Error:

Failed building wheel for pythonnet
I took a look as well at https://github.com/pythonnet/pythonnet/wiki/Installation but it didn't helped.
So this fails as well:
/usr/bin/python3 -m pip install git+https://github.com/pythonnet/pythonnet --user
I tried as well with and without the --egg option.
By the way I'm behind a proxy server. So I tried as well to set the proxy server for NuGet, see NuGet Behind Proxy:
mono /usr/lib/nuget/nuget.exe config -set http_proxy=http://my.proxy.address:port
Any idea what I'm doing wrong?
回答1:
I was able to install it with the following commands:
sudo apt update
sudo apt-get install clang
sudo apt-get install libglib2.0-dev
sudo apt install git
sudo apt install nuget
git config --global http.proxy http://my.proxy.address:port
mono /usr/lib/nuget/nuget.exe config -set http_proxy=http://my.proxy.address:port
/usr/bin/python3 -m pip install -U pycparser --user
/usr/bin/python3 -m pip install -U git+https://github.com/pythonnet/pythonnet --user --egg
回答2:
Change ownership of the file in question. I was having a similar with dotnet and what i did was to change the ownership of the file or folder.
sudo chown -R $user:$user /path_to_file
