Python Cmd/Powershell error Traceback Most recent call last

Question

我在看“Learn Python The Hard Way”教程，当它告诉我在安装后在Powershell中键入Python来尝试它时，它一直给我这样的信息：

PS C:\Users\Zach> python
Traceback (most recent call last):
File "C:\Python27\lib\site.py", line 548, in <module>
main()
File "C:\Python27\lib\site.py", line 530, in main
known_paths = addusersitepackages(known_paths)
File "C:\Python27\lib\site.py", line 266, in addusersitepackages
user_site = getusersitepackages()
File "C:\Python27\lib\site.py", line 241, in getusersitepackages
user_base = getuserbase() # this will also set USER_BASE
File "C:\Python27\lib\site.py", line 231, in getuserbase
USER_BASE = get_config_var('userbase')
File "C:\Python27\lib\sysconfig.py", line 516, in get_config_var
return get_config_vars().get(name)
File "C:\Python27\lib\sysconfig.py", line 449, in get_config_vars
import re
File "C:\Python27\lib\re.py", line 105, in <module>
import sre_compile
File "C:\Python27\lib\sre_compile.py", line 14, in <module>
import sre_parse
File "C:\Python27\lib\sre_parse.py", line 17, in <module>
from sre_constants import *
File "C:\Python27\lib\sre_constants.py", line 18, in <module>
from _sre import MAXREPEAT
ImportError: cannot import name MAXREPEAT

我还尝试运行命令提示符，得到了相同的错误。我已经安装和卸载了大约3次python，并且做了一些重新引导，但都没有用。我对python很陌生，我对在这里做什么感到困惑。我也很感激其他python教程的链接。

在这种情况下，根据我的理解，您没有名为“maxprepeat”的模块，或者您（或安装程序）在错误的地方安装了它。重新安装或重定向路径应该可以使其正常工作。
