pylab ImportError:没有名为_thread的模块

Question

从ubuntu 10.04开始,我用easy_install安装了pylab.经过一些升级,我可以导入pylab.首先,我从easy_install运行ipython:

$ ipython
Python 2.6.5 (r265:79063, Apr 16 2010, 13:09:56) 
Type "copyright", "credits" or "license" for more information.

IPython 0.11 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.

然后我尝试导入matplotlib

In [1]: import matplotlib

In [2]: matplotlib.__version__
Out[2]: '1.0.1'

但是当导入pylab failes时如下:

In [3]: import matplotlib.pylab

     14 import sys
     15 

ImportError: No module named _thread

这可能是python_dateutil问题.我删除了与synaptic一起安装的旧版本(1.4.3)但不能解决问题.

如何在不重新安装的情况下修复它？谢谢.让 - 帕特里克

Answer 1

它是由dateutil引起的.

如您所见,您已使用easy_install 安装了dateutil 2.0,但它与python 2.x不兼容.您应该卸载(或只删除整个文件夹)2.0版本,然后转到其主页并下载1.5版,然后手动安装它.

版本2.0适用于Python 3.x,您也可以在主页上找到它.

--UPDATE--

dateutil 2.1过时了,现在是不是需要使用1.5了,如果你能忍受six得到安装太:)
