python - "File too short"与 Tableau 数据提取 API(Python 和 Linux)

Question

Tableau 最近将一些面向开发人员的工具从仅限 Windows 扩展到了 Linux。下载后 Tableau Data Extract API Linux(64 位，版本 8.1)上的 Python (2.7) 库，我提取文件并使用标准“python setup.py install”安装库

尝试使用适用于 Windows 的代码运行时，出现以下错误:

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
File "/usr/local/lib/python2.7/dist-packages/dataextract/__init__.py", line 15, in <module>
  from Base import *
File "/usr/local/lib/python2.7/dist-packages/dataextract/Base.py", line 17, in <module>
  from . import StringUtils
File "/usr/local/lib/python2.7/dist-packages/dataextract/StringUtils.py", line 17, in <module>
  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

如何解决这个“文件太短”错误？

Answer 1

复制或提取库时出现错误，链接实际上是文件。一个类似的例子是 here .

您需要删除应该是链接的文件，然后重新链接它们。

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