如何在AmazonLinux2M6G实例中安装pyarrow

Question

我正在尝试在AmazonLinux2M6G实例中安装pyarrow，该实例具有ARM架构。我已经安装了几个依赖项，现在运行pip3.8 install pyarrow时遇到了这个错误：

-- Found the Arrow core static library: /usr/lib64/libarrow.a
    -- Could NOT find ArrowPython (missing: ArrowPython_DIR)
    -- Checking for module 'arrow-python'
    --   No package 'arrow-python' found
    CMake Error at /usr/local/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:165 (message):
      Could NOT find ArrowPython (missing: ARROW_PYTHON_INCLUDE_DIR
      ARROW_PYTHON_LIB_DIR) (found version "2.0.0")
    Call Stack (most recent call first):
      /usr/local/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:458 (_FPHSA_FAILURE_MESSAGE)
      cmake_modules/FindArrowPython.cmake:76 (find_package_handle_standard_args)
      CMakeLists.txt:215 (find_package)

它说我需要安装包ArrowPython。当我运行sudo yum install arrow-python-libs来安装此软件包时，出现以下错误：

Error: Package: openblas-threads-0.3.3-2.el7.aarch64 (epel)
           Requires: libgfortran.so.3()(64bit)

Error: Package: openblas-serial-0.3.3-2.el7.aarch64 (epel)
           Requires: libgfortran.so.3()(64bit)
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我也尝试过其他pyarrow版本，但我得到了相同的错误

我怎样才能解决这个问题

Answer 1

我无法通过conda安装。或者当我尝试import pyarrow时conda one出现导入错误。但它成功了。安装conda后，通过：

pip install pyarrow=2
