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自学编程网。如有错误或未考虑完全的地方，望不吝赐教。
