Error installing Python Django using pip on Windows 8

Question

I am using Python 2.7 and pip to install Django on Windows 8 and encountered an Errno22. I typed "python -m pip install Django==1.7" and get

...
...
File "D:\Python27\lib\site-packages\pip\util.py", line 508, in unzip_file
fp = open(fn, 'wb')
IOError: [Errno 22] invalid mode ('wb') or filename: 'c:\\users\\[username]~1\\appda
ta\\local\\temp\\pip_build_[username]\\django\\django/contrib/admin/locale/l
t/LC_MESSAGES/django.mo'

Looks like it's a typical backslash problem of pip on Windows. I tried to modify the code in util.py but with in vain. This is an Administrator command prompt so privilege should not be the cause. Any ideas how to resolve this?

@AshwiniChaudhary Just to avoid version conflict. "pip install Django==1.7" gives the same result. — Andy Wang

You are unnecessarily adding an extra parameter: python -m pip install Django==1.7

It should be:

python pip install Django==1.7

It's hardly because of this reason. I only added this to avoid version conflicts. I can of course just type "pip install Django==1.7", but it will give the same result.
