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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
