env装好了，执行scons的时候，报错是哪里的问题？

按住官方文档配置完了。然后运行scons，然后就报错：

• Dependency packages missing, please running 'pkgs --update'...
  

我继续pkgs --update，然后就报错：

• 'pkge' is not recognized as an internal or external command,
  
• operable program or batch file.
  

然后执行menuconfig -s，继续报错：

• Traceback (most recent call last):
  
•   File "D:rtthreadenvtoolsConEmuConEmu......toolsscriptsenv.py", line 39, in
  
•     from cmds import *
