python - 尝试从 pyevolve 导入时出现 "AttributeError: fileno"

Question

我刚刚使用 easy_install 安装了 Pyevolve，在尝试运行我的第一个程序时遇到错误。我首先尝试复制并粘贴 first example 的源代码但这是我尝试运行它时收到的信息:

Traceback (most recent call last):
File "/home/corey/CTest/first_intro.py", line 3, in
from pyevolve import G1DList
File "/usr/lib/python2.6/site-packages/Pyevolve-0.5-py2.6.egg/pyevolve/init.py", line 15, in
File "/usr/lib/python2.6/site-packages/Pyevolve-0.5-py2.6.egg/pyevolve/Consts.py", line 240, in

File "/usr/lib/python2.6/site-packages/Pyevolve-0.5-py2.6.egg/pyevolve/Util.py", line 20, in
AttributeError: fileno

我在 Fedora 11 X86_64 上运行 python 2.6。

编辑:经过更多研究后，如果我从命令行运行 python，它可以工作，但只有在我运行 IDLE 时才会失败。

您是否尝试过查看开发版本？它接近 RC1，所以现在很稳定:svn co https://pyevolve.svn.sourceforge.net/svnroot/pyevolve/trunk pyevolve

您的问题似乎是路径，请尝试解压缩“egg”文件并将“pyevolve”目录放入站点包或应用程序目录中。
