Wes McKinney commented on ARROW-66:
-----------------------------------
Did you install the Python library after you installed libarrow.so? It sets an
rpath based on the $ARROW_HOME variable.
In my experience, using RPATH is very difficult across platforms, so we may
need to revert the defaults to use system paths for everything.
> Maybe some missing steps in installation guide

> Key: ARROW-66
> URL: https://issues.apache.org/jira/browse/ARROW-66
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Environment: CentOS 7.0; Python 2.7.x
> Reporter: Qian Xu
> Labels: documentation
>
> I followed [the
> guide|https://github.com/apache/arrow/blob/master/python/doc/INSTALL.md] 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.
