This is probably due to newer Mono 5.12 version than Mono 5.10 that we are testing against:

#654

Mono 4.2 is too old, follow installation from official Mono website or better follow our travis-ci script:

@harryln the error in your build is most likely due to missing dependency (python-dev), please follow travis ci build script to install all dependencies:

src/monoclr/pynetclr.h:4:20: fatal error: Python.h: No such file or directory

Dear @denfromufa, Many thanks for your reply.

After installingpython-dev by

sudo -H apt install python-dev

I then try again:

sudo -H pip install git+https://github.com/pythonnet/pythonnet     ## pythonnet 2.4.0.dev0

it works.
But:

sudo -H pip install pythonnet       ## pythonnet 2.3.0

still does not work.

One of packages I use needs pythonnet 2.3.0. I wonder whether or not I can install pythonnet 2.3.0 via pip install git+.

Many thanks again for your time.

@harryln you can install pythonnet 2.3 if you install the corresponding Mono version, probably 4.8.0. But I highly recommend the pythonnet master branch (2.4.0.dev1).
