这几天用到scons遇到个问题，特来请教，若能指点，不胜感激。描述如下：
winXPsp3
socon-2.0.1
python-2.7.3
rt-thread 1.1.0 stm32f10x分枝
以上为安装环境和软件版本号。
按照官方wiki的步骤进行操作，环境变量已添加```C:Python27;C:Python27Scripts;C:Program FilesCodeSourcerySourcery G++ Litein;C;Python27Libsite-packagesscons-2.0.1sCons;```，采用gcc作为编译器，其rtconfig.py主要部分配置如下：
```import os

# toolchains options
ARCH='arm'
CPU='cortex-m3'
CROSS_TOOL='gcc'

if os.getenv('RTT_CC'):
	CROSS_TOOL = os.getenv('RTT_CC')

#device options
# STM32_TYPE = 
# 'STM32F10X_LD','STM32F10X_LD_VL',
# 'STM32F10X_MD','STM32F10X_MD_VL',
# 'STM32F10X_HD','STM32F10X_HD_VL',
# 'STM32F10X_XL','STM32F10X_CL'
STM32_TYPE = 'STM32F10X_HD'

# lcd panel options
# 'FMT0371','ILI932X', 'SSD1289'
RT_USING_LCD_TYPE = 'SSD1289'

# cross_tool provides the cross compiler
# EXEC_PATH is the compiler execute path, for example, CodeSourcery, Keil MDK, IAR

if  CROSS_TOOL == 'gcc':
	PLATFORM 	= 'gcc'
	EXEC_PATH 	= 'C:/Program Files/CodeSourcery/Sourcery G++ Lite/bin'
elif CROSS_TOOL == 'keil':
	PLATFORM 	= 'armcc'
	EXEC_PATH 	= 'C:/Keil'
elif CROSS_TOOL == 'iar':
	PLATFORM 	= 'iar'
	IAR_PATH 	= 'C:/Program Files/IAR Systems/Embedded Workbench 6.0 Evaluation'

if os.getenv('RTT_EXEC_PATH'):
	EXEC_PATH = os.getenv('RTT_EXEC_PATH')

BUILD = 'debug'```
dos环境下执行scons命令后，出现UnicodeDecodeError: 的错误，见下图：

在网上查找方法并不奏效，其中合理的一种为
```import sys 
reload(sys) 
sys.setdefaultencoding('utf8')```但是不好使，依然会报错，请指正，将不胜感激
