If you check the available files listings for PyArrow 3.0.0 on PyPI, you’ll see that there are only manylinux2010 and manylinux2014 wheels.The pip in Ubuntu 18.04 is too old, so it only knows about manylinux1.

Here’s the problem: old versions of pip don’t support manylinux2010, and certainly not manylinux2014. You can see which variant is being used in the filename of the wheel you’re downloading. If pip sees a wheel that will work for your specific version of Python and operating system version, it will download it instead of the source code.įor Linux, there are multiple wheel variants: manylinux1, manylinux2010, and manylinux2014. In order to save you the need to compile everything from scratch, maintainers can upload a compiled version of the code-”wheels”-to the Python Package Index. Many packages-from NumPy to Cryptography-require compiling some code in C/C++/Cython/Rust/etc. Why did an old version get installed? pip and manylinux wheels
