UnicodeDecodeError: 'ascii' codec can't decode byte 0xd6 in position 19: ordinal not in range(128)

i believe this is due to my no-ascii characters in the path, but i don`t know how to handle this, can you help me?
thanks in advance.

Limitation of Python 2.x

I don't think I put an option in this script to change the download location, so your best bet is probably to install pip yourself. The pip documentation for this is at http://pip.readthedocs.org/en/latest/installing.html#install-pip

If you're still running into the same issue after pip is installed, you can create a config file as described at http://pip.readthedocs.org/en/latest/user_guide.html#configuration and set:
build=<a path with only ascii characters>
Also, I'd expect pip to work fine for Python 3; this issue probably only exists for Python 2.

hi Zooba,
i followed your hint, but still got the same error.
i try to install pip individually and it seems like the download zip file will always be put on path like this: 'c:\users\中文字符\appdata\local\temp\tmpdrg4_t\pip.zip\pip\' :(

so, i user second method. this is my pip.ini file:
build = e:\
and i put it just in the root of e: (e:)
well, at last i still get the same error.

am i misunderstood something?
thank you.

sorry, my apology.
forget about the second method. (it requires the pip was installed successfully)
so, the first method i tried was still give me the error msg. is there any other workaround i can handle this?
thank you

at last i found the solution, a simple one:
just modify the evn variable 'TEMP'&'TMP'
'%USERPROFILE%\AppData\Local\Temp' => 'path without no-ascii characters\AppData\Local\Temp'

that`s all. hope this will help others who encounter the same question :)

Glad that was resolved. Python 3.x should work fine, FYI; one of the main changes was intended to prevent issues like this.
