我在先后安装了Python(x,y)-2.6.2.0.exe和Python(x,y)-2.6.5.1.exe后，都不能启动Python(x,y)，任务管理器中也没有看到相应的进程。网上也没搜索到类似的信息。请各位指教，谢谢！

我的系统：Winxp

我没有遇到这样的问题，不过有读者遇到过，他的解决办法是：将快捷方式所对应的pyw改名为py。你可以先试试看。

另外，你可以在命令行中运行python(x,y)，这样可以查看它的出错信息。看能不能根据出错信息找到原因。

最后，xyhome.pyw只是一个方便启动其它程序的界面。其大部分功能都可以在Python(x,y)的开始菜单中找到直接启动的快捷方式。我一般是直接启动IPython或者Spyder进行开发。

我也是同样的问题，

我是这样解决的。

将快捷方式对应的pyw文件，更改后缀名为py，这样就可以了

但是会多出来一个命令行。

不过还好不会影响使用。

我把pyw改为py后还是不能启动Python(x,y)。

是不是之前安装过python程序，就会出现这种情况？

用命令行启动试试看，看看报错信息。

在命令行中执行xyhome.pyw，依然没有反应。

右键,Run In Interactive Mode ，有如上错误信息。

根据下面的报错信息，我猜你的Windows用户文件夹有中文

filename=osp.join(STARTUP_PATH, CONF.get(None, 'startup')) 
  File "C:\Python26\lib\ntpath.py", line 108, in join 
    path += "\\" + b 
UnicodeDecodeError: 'ascii' codec can't decode byte 0xcd in position 26: ordinal 

在Python交互环境中输入下面的语句，看看你的用户文件夹是什么：

>>> import os.path as p

>>> p.expanduser("~")

我想可以通过环境变量HOME修改此文件夹，不过更好的解决办法是修改

filename=osp.join(STARTUP_PATH, CONF.get(None, 'startup')) 

使它使用合适的文字编码。等我有空试试看。

UnicodeDecodeError: 'ascii' codec can't decode byte 0xcd in position 26: ordinal
 not in range(128)
>>> import os.path as p
>>> p.expanduser("~")
'C:\\Documents and Settings\\\xcd\xf5\xc0\xa4'
>>>

怎样修改环境变量HOME，怎样使用 filename=osp.join(STARTUP_PATH, CONF.get(None, 'startup'))  ？

我安装pythonxy的时候是把本机的phton2.6给卸载了的。

改名以后就可以正常运行了。

不过大多的功能都可以直接在开始菜单下面找到。

不能运行这个快捷方式，也是没有什么关系的

找到原因和解决办法了。因为WindowXP的环境变量不是使用Unicode，因此通过环境变量读入用户文件夹时需要指定编码，具体解决办法如下：

编辑
c:\python26\lib\site-packages\xy\userconfig.py

的get_home_dir()函数，将57行左右的：

if path:
   return path

改为：

if path:
   return path.decode("cp936")

或者
if path:
   import locale
   return path.decode( locale.getpreferredencoding() )

Traceback (most recent call last):
  File "C:\Python26\Scripts\xyhome.pyw", line 20, in <module>
    from xy import xyhome
  File "C:\Python26\lib\site-packages\xy\xyhome.pyw", line 28, in <module>
    from xy.config import (CONF, STARTUP_PATH, LOG_PATH, PLUGINS, XY_VERSION,
  File "C:\Python26\lib\site-packages\xy\config.py", line 33, in <module>
    CONF = UserConfig('xy', defaults=DEFAULTS, version=__version__, subfolder='.
xy')
  File "C:\Python26\lib\site-packages\xy\userconfig.py", line 94, in __init__
    self.load_from_ini()
  File "C:\Python26\lib\site-packages\xy\userconfig.py", line 120, in load_from_
ini
    self.read(self.filename())
  File "C:\Python26\lib\site-packages\xy\userconfig.py", line 149, in filename
    folder = osp.join(folder, self.subfolder)
  File "C:\Python26\lib\ntpath.py", line 96, in join
    assert len(path) > 0
TypeError: object of type 'NoneType' has no len()
>>>

两种方法都试了，还是有错误。

在Python命令行输入

>>> import xy.userconfig as u

>>> u.get_home_dir()

看看是什么结果？

报错信息的意思是说get_home_dir()返回的是None，不应该啊。

正在重装，RY大哥请等几分钟！

双击Python(x,y)还是不能启动，但是右键，Run In Interactive Mode ，可以启动。

那就和邹建遇到的问题一样了，将pyw扩展名修改成py，应该也可以启动。就是要带那个命令行窗口。

很奇怪，现在将get_home_dir()函数还原，右键Run In Interactive Mode 也可以启动Python(x,y)。

如果用邹建的方法，将pyw改为py，则双击Python(x,y)也可以启动。

RY大哥的操作系统应该是英文版的吧？
