Mac M2でhdf5のインストール

問題

使いたいpythonモジュールでhdf5が必要だった。

brew install hdf5@1.8
export HDF5_DIR=/opt/homebrew/Cellar/hdf5@1.8/1.8.22_2

で指定してpipするも、以下のようにhdf5の場所がわからないと言われる。

Collecting tables>=3.0 (from ******)

         You may need to explicitly state where your local HDF5 headers and
         library can be found by setting the ``HDF5_DIR`` environment
         variable or by using the ``--hdf5`` command-line option.
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
