关于gdesklets的问题（已解决）

提示缺少pygtk，确认发现pygtk已安装
（期间参考gentoo bug ，emerge python 2.4 ,系统默认已安装python 2.5)

另外我给你的那个命令是让你看你的系统里pygtk的路径应该在什么地方
然后你自己看看那里是否真的有pygtk

我得到结果和老大你说的一样
python -c 'import sys; print sys.path' | grep -o '/usr[^ ]*gtk-2.0'
/usr/lib/python2.5/site-packages/gtk-2.0
这个可以说明什么吗？
这是该目录下的情况

如果你对一个问题完全不理解，而你想通过搜索来寻找答案
你需要寻找和你的症状完全一样的，版本完全一样的，发行版一样的，而且发生时间差不太多的问题的答案
否则，如果盲目的照做的话，很可能会把问题搞的更糟

你可以一步一步的调试
首先删掉python2.4，看问题是否存在。因为不管怎样，你都不需要通过安装旧的python版本来解决问题。
然后确认你是否可以在python里手动import gtk
执行python回车，输入import gtk看看是否成功
如果不行，ctrl-d退出
然后执行python -v，再import gtk看看是读取什么文件的时候出了问题
如果手动import没有问题，那我怀疑你的系统里还有别的python，而gdesklet调用了那个python，但那个python不能import。或者gdesklet import gtk时，sys.path被修改，pygtk的路径被从里面删掉。你可以在import gtk那句话前面加上
import sys
print sys.path
来检查sys.path里确实有pygtk的路径

/usr/lib/python2.5/site-packages/cairo/
有这个么？

如果没有估计是当时升级python的时候没有执行python-updater

运行python-updater似乎要emerge好几个ebuild，所以没有做，等会试下

lifesucks

运行python-updater
显示Couldn't determine any previous Python version(s).
可能是因为把2.4 unemerge 掉的缘故，妄猜。

加入python-updater --old-version 2.4
emerge 依赖的ebuild后
显示一系列需要升级，开始emerge 计87项，可能和我的USE列的太多有关，ctrl－D，只
emerge －av '=dev-python/pycairo-1.4.12'
emerge -av pygtk

gdesklets 启动正常
至此非常感谢boss和其他的弟兄的帮助，谢谢

zhllg

你后来又运行了python-updater么？
升级python的时候这个步骤是不能省的
