“File too short” with Tableau Data Extract API (Python and Linux)

问题

Tableau recently expanded some tools for developers to Linux, from Windows-only. After downloading the Tableau Data Extract API libraries for Python (2.7) on Linux (64Bit, version 8.1), I extracted the files and installed the libraries using the standard 'python setup.py install'

When trying to run with a code that works on Windows, I get the following error:

Traceback (most recent call last):
File "apache.py", line 280, in <module>
  print create_tableau(tsvfile)
File "apache.py", line 136, in create_tableau
  import dataextract as tde

  tablib = libs.load_lib
File "/usr/local/lib/python2.7/dist-packages/dataextract/Libs.py", line 35, in load_lib
  self.lib = ctypes.cdll.LoadLibrary(self.lib_path)
File "/usr/lib/python2.7/ctypes/__init__.py", line 443, in LoadLibrary
  return self._dlltype(name)
File "/usr/lib/python2.7/ctypes/__init__.py", line 365, in __init__
  self._handle = _dlopen(self._name, mode)
OSError: /usr/local/lib/python2.7/dist-packages/dataextract/lib/../lib/libicuio.so.50: file too short

How can I fix this 'file too short' error?

回答1:

There is an error when copying or extracting the libraries, where the links are actually files. A similar example is here.

You need to remove the files that are supposed to be links, and then re-link them.

cd /usr/local/lib/python2.7/dist-packages/dataextract/lib/../lib/

rm libicudata.so.50 && ln -s libicudata.so.50.1.2 libicudata.so.50
rm libicui18n.so.50 && ln -s libicui18n.so.50.1.2 libicui18n.so.50
rm libicuio.so.50 && ln -s libicuio.so.50.1.2 libicuio.so.50
rm libicule.so.50 && ln -s libicule.so.50.1.2 libicule.so.50
rm libiculx.so.50 && ln -s libiculx.so.50.1.2 libiculx.so.50
rm libicutu.so.50 && ln -s libicutu.so.50.1.2 libicutu.so.50
rm libicuuc.so.50 && ln -s libicuuc.so.50.1.2 libicuuc.so.50
