“import numpy”会导致一个Eclipse工作区出错,但不会导致另一个Eclipse工作区出错。

每当我尝试在Eclipse和Pydev的新安装中导入numpy时,都会出现以下错误:

Traceback (most recent call last):
  File "Q:\temp\test.py", line 1, in <module>
    import numpy
  File "C:\Python26\lib\site-packages\numpy\__init__.py", line 132, in <module>

  File "C:\Python26\lib\site-packages\numpy\core\defchararray.py", line 23, in <module>
    from numpy.core.multiarray import _vec_string
ImportError: cannot import name _vec_string

然而,在vanila python控制台和ipython中,导入是成功的。

为了使事情更加复杂,在另一个Eclipse工作区中,这个导入工作正常。重启Eclipse没有帮助。我还尝试在首选项中重新配置解释器->python->解释器->python(如 this question 但是问题仍然存在

在SO上描述了另外两个类似的问题。( this 和 this 但这两个问题都是用Ironpython观察到的,我在提供的几个答案中找不到任何可以使用的地方。

编辑 AS suggested by dutt ,我检查了两个测试工作区(工作区和不工作区)中的首选项->pydev->解释器python->库。故障工作区在系统libs c:\python26\lib\site packages\numpy-1.5.0-py2.6-win32.egg中包含以下库。另一方面,工作区没有列出任何 麻木的 系统库列表中的库。我已经从“不工作”工作区的列表中删除了上述库。
