Question

Getting the error below trying to install ez_install, Windows 7 64 bit machine with fresh Python 2.7. Any ideas?

Something went wrong during the installation.

Answer 1

I met the same problem, solved it by deleting non-ASCII character in window registry "HKEY_CLASSES_ROOT\MIME\Database\Content Type" and it works.The reason is

 ctype = ctype.encode(default_encoding)  

will throw UnicodeDecodeError when it met non-ASCII characters and the program will stop.

Answer 2

Check this link.(http://blog.csdn.net/hugleecool/article/details/17996993).

In C:\Python27\Lib\mimetypes.py find next string

default_encoding = sys.getdefaultencoding()

replace it with

if sys.getdefaultencoding() != 'gbk':  
    reload(sys)  
    sys.setdefaultencoding('gbk')  
default_encoding = sys.getdefaultencoding()

Notice: instead 'gbk' choose your encoding.

Answer 3

In C:\Python27\Lib\mimetypes.py find next string

default_encoding = sys.getdefaultencoding()

replace it with

if sys.getdefaultencoding() != 'gbk':  
    reload(sys)  
    sys.setdefaultencoding('gbk')  
default_encoding = sys.getdefaultencoding()

Notice: instead 'gbk' choose your encoding.

The above answer satisfies my case of unicode decode error in using google app engine local web server for php and python .

Answer 4

In my case, simply comment the following four line worked,

try:
    ctype = ctype.encode(default_encoding) # omit in 3.x!
except UnicodeEncodeError:
    pass

And replace UnicodeEncodeError to be UnicodeError worked.
