python - pylab导入错误: No module named _thread

Question

从 ubuntu 10.04 开始，我使用 easy_install 安装了 pylab。升级后，我可以导入 pylab。首先，我运行从 easy_install 安装的 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'

但是导入pylab失败如下:

In [3]: import matplotlib.pylab

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)，但这并没有解决问题。

如何在不重新安装所有内容的情况下修复它？谢谢你。让-帕特里克

Answer 1

这是由 dateutil 引起的。

如您所见，您已经使用 easy_install 安装了 dateutil 2.0，但它与 python 2.x 不兼容。您应该卸载(或删除整个文件夹)2.0 版本，然后转到其 homepage并下载 1.5 版本，然后手动安装。

版本 2.0 适用于 Python 3.x，您也可以在主页上找到它。

--更新--

dateutil 2.1 已经出来了，现在不需要再使用 1.5，如果你能忍受 6 也安装 :)
