Subject [jira] [Created] (ARROW-66) Maybe some missing steps in installation guide
Date Tue, 15 Mar 2016 03:00:39 GMT
Qian Xu created ARROW-66:
----------------------------

             Summary: 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
            Reporter: Qian Xu


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.
