Hello there - thanks for reporting this @DjeridiY.

Can you please provide more of your error log? This looks like a symptom of an earlier error.

I am attaching a file which is the result of my installation (sorry for the scrolling speed, I can't upload a file that's too long).

Thanks for sharing this. The pyne_version.h file should be build during the CMake step by running a python script. The current command assumes that the python command is available, however, some systems only have python3. Can you confirm whether your system has the python command available (e.g. which python)?

Have you installed all the dependencies before installing PyNE?

To install PyNE, you need to install the following dependencies:

sudo apt-get install software-properties-common \
                  python3-pip \
                  wget \
                  build-essential \
                  git \
                  cmake \
                  gfortran \
                  libblas-dev \
                  liblapack-dev \
                  libeigen3-dev \
                  libhdf5-dev \
                  hdf5-tools

Once the dependencies are installed, you can proceed with installing the required Python packages using pip:

pip3 install numpy \
                  scipy \
                  cython \
                  nose \
                  pytest \
                  tables \
                  matplotlib \
                  jinja2 \
                  setuptools \
                  future \
                  progress

Additionally, I recommend creating a virtual environment before installing PyNE.

To say more on this.... one some systems, when python3 is installed, it does NOT also make a link to the python command. A common solution is to update-alternatives to tell your system that any call to python should be fielded by running python3.

Creating a virtual environment solved the same issue in my case but don't know why the issue arises and why I need to create that venv

[ahnaf-tahmid-chowdhury]

Hi @Minhajur-NE-25, you might have unsupported dependency packages installed in your local dir or system-wide Python, which was causing PyNE installation failure. Creating a virtual env is a best practice to isolate project dependencies, preventing conflicts with other projects or the system-wide Python installation.
