Press any key to close this message and halt the script. \n\n------------------------------\n-------- Installation --------\n------------------------------\n\nSee: https://pypi.org/project/pypandoc/\n\nPypandoc uses pandoc, so it needs an available installation of pandoc. For some common cases (wheels, conda packages), pypandoc already includes pandoc (and pandoc-citeproc) in it’s prebuilt package.\n\n------------------------------\n----- Installing via Pip -----\n------------------------------\n\nInstall via pip:\n\n     pip install pypandoc\n\nPrebuilt wheels for Windows and Mac OS X include pandoc. If there is no prebuilt binary available, you have to install pandoc yourself.\n\nIf you use Linux and have your own wheelhouse, you can build a wheel which include pandoc with python setup.py download_pandoc; python setup.py bdist_wheel. Be aware that this works only on 64bit intel systems, as we only download it from the official releases.\n\n------------------------------\n---- Installing via Conda ----\n------------------------------\n\nPypandoc is included in conda-forge. The conda packages will also install the pandoc package, so pandoc is available in the installation.\n\nInstall via conda: \n\n     install -c conda-forge pypandoc\n\nYou can also add the channel to your conda config via conda config --add channels conda-forge. This makes it possible to use conda install pypandoc directly and also lets you update via conda update pypandoc.\n\nPress any key to exit the this message and halt the script.\n')
