What solution would you recommend? I am using Windows 8.1 machine.

回答1:

I am on Windows 7. I came across the same bug. I read the discussion here. It seems to be caused by UTF-8 support if you have English Windows.

Just type:

chcp 1252

then run your pip again.

The reason for the PermissionError was because i changed registry code page to 65001: REG ADD HKCU\Console /v CodePage /t REG_DWORD /d 65001 /f So, remove the autorun registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor. If you want to use utf-8 ( 65001) just use chcp 65001 on command prompt.
