解决python 出现unknown encoding: idna 的问题

这个问题是编码的问题在开头导入个包就行了，简答粗暴

import encodings.idna

补充：执行python出现lookuperror: unknown encoding: cp65001解决办法

在执行fetch v8时出现

e:\gitproject\svn_v8>fetch v8
running: 'e:\gitproject\libcef\depot_tools\python276_bin\python.exe' 'e:\gitproj
ect\libcef\depot_tools\gclient.py' root
traceback (most recent call last):
file "e:\gitproject\libcef\depot_tools\\fetch.py", line 353, in <module>
sys.exit(main())
file "e:\gitproject\libcef\depot_tools\\fetch.py", line 348, in main
return run(options, spec, root)
file "e:\gitproject\libcef\depot_tools\\fetch.py", line 342, in run
return checkout.init()
file "e:\gitproject\libcef\depot_tools\\fetch.py", line 134, in init
self.run_gclient('config', '--spec', self._format_spec())
file "e:\gitproject\libcef\depot_tools\\fetch.py", line 76, in run_gclient
return self.run(cmd_prefix + cmd, **kwargs)
file "e:\gitproject\libcef\depot_tools\\fetch.py", line 63, in run
print 'running: %s' % (' '.join(pipes.quote(x) for x in cmd))
lookuperror: unknown encoding: cp65001

lookuperror: unknown encoding: cp65001

出现此错误后改变编码方式即可解决：

chcp 1252

也可以通过修改注册表codepage值来设置默认字符编码

hkey_current_user\console\%systemroot%_system32_cmd.exe\codepage

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。如有错误或未考虑完全的地方，望不吝赐教。
