> I followed [the guide|]
to install Arrow project from scratch. I met some issues.
> 1. First of all, I need to build the cpp part. So I setup the thirdparty dependencies.
But when I {{cmake -DCMAKE_INSTALL_PREFIX=$ARROW_HOME ..}}, it shows an error at {{get_filename_component}}
with {{FindGTest.cmake}}. After some digging, I noticed that I have to use *cmake 3* (instead
of cmake 2).
> 2. Now I am able to install {{pyarrow}}. The installation went smooth. But when I import
the module {{pyarrow}}, it says {{ImportError: No module named array}}. I haven't found any
description on this error.
