extreme4all commented 4 years ago

python version: Python 3.8.2 command: pip install fastparquet

error: Building wheels for collected packages: fastparquet Building wheel for fastparquet (setup.py) ... error

` building 'fastparquet.speedups' extension error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/

ERROR: Failed building wheel for fastparquet `

i tried https://www.scivision.dev/python-windows-visual-c-14-required/

any suggestions? would love to use this tool as parquet seems to be fast and efficient way of storing data

Indeed the build dependencies of fastparquet are not well specified, because it has binary extensions, and many people install via conda for this very reason. The module in question is cython code, and you will need a full compiler toolchain available on your system for the build to succeed.

extreme4all commented 4 years ago

i guess it is not as simple as pip install Cython

martindurant commented 4 years ago

No, sorry. That just installs the cython library, but if you're not using conda, the compilers and system libraries must be installed by you (or a sysadmin)

extreme4all commented 4 years ago

I'm not using conda, which compilers and system libraries must I install? would be nice if you can list them & where to find them.

martindurant commented 4 years ago

I don't know for windows :| You might want to check what conda-forge uses as it's build environment or generally search for cython/numpy/windows setup.

That is why conda has proven so helpful to people...
