UnicodeDecodeError: 'ascii' codec can't decode byte 0xc7 in position 7: ordinal not in range(128)

Question

Before asking this question, I have searched SO, find several related links:UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 13: ordinal not in range(128), regarding reading in files

But they are no useful for my post, all of them are about program, but mine is for installation.

After I install the pip, I check the pip list:

C:\Users\中jin>pip list
DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
pip (9.0.1)
setuptools (28.8.0)

When I install django use pip, I get the bellow error:

C:\Users\中jin>pip install django
Collecting django
Exception:

    result_path = result_path + p_path

EDIT-1

I am in Windows10, and python 2.7.

I suspect that your temporary directory contains a non-ASCII 7 bit character in the actual path.

If you are on Windows make sure that the environment variable %TEMP% is set to a directory that only uses in it's full path the values in the ranges A-Za-z0-9 no accented characters, symbols, etc.

Note

On windows 10 and python 2.7.13 I have just tested and got:

> pip install django
