[Gmsh] gmsh-sdk installation question

[Peter Johnston]

Thanks Kenneth,

That all worked fine.

I still don't know what was wrong with the other approach.

Thanks again,

Peter.

Subject: Re: [Gmsh] gmsh-sdk installation question

Good morning,

I had the same problem a few weeks ago. You can try to: install gmsh in a virtual env<https://docs.python.org/3/library/venv.html> or put it manually in python path :

- Enter in the home directory :
cd ~

- [Download the SDK](http://gmsh.info/bin/<http://gmsh.info/bin/>) depending on your system
wget http://gmsh.info/bin/Linux/gmsh-4.5.6-Linux64-sdk.tgz<http://gmsh.info/bin/Linux/gmsh-4.5.6-Linux64-sdk.tgz> -O /tmp/gmsh-sdk.tar.gz

- Uncompress it
tar -xvf /tmp/gmsh-sdk.tar.gz

- Open the *~/.bashrc* file and add to the last line
export *PYTHONPATH="${PYTHONPATH}":~/gmsh-4.5.6-Linux64-sdk/lib/

- source the *.bashrc* file
source ~/.bashrc

- test if all is ok
python3 gmsh-4.5.6-Linux64-sdk/share/doc/gmsh/demos/api/t1.py


Best regards,
Kenneth,

Hello,

I have a question about gmsh/gmsh-sdk installation under python - I realise this is not a gmsh question exactly, so hope it is OK.

I was trying to install gmsh and gmsh-sdk on a computer running ubuntu 18.04 using 'pip3 install gmsh' (I also tried 'pip3 install gmsh-sdk'). On my mac laptop (OSX 10.15.4) this works fine. It puts the appropriate python gmsh files under /usr/local/ and everything works fine. However under ubuntu it installed to files under $HOME/.local/ and python3 says it cannot find the gmsh module.  I have modified the PYTHONPATH variable to take into account $HOME/.local/, but this doesn't help.

I really don't know what is going on on two fronts:

  1.  I don't know why pip is installing things in different places between my two machines.
  2.  When I type print(sys.path) in python it points to the places where I think gmsh should be. Which files am I looking for exactly?

After a long time trawling the internet, I couldn't find anything that would help me with these issues.

Any insights would be much appreciated.

Thank you,

Peter.
