  • pip 安装pandas报UnicodeDecodeError: 'ascii' codec can't decode byte 0xd5错

    Python在window环境中通过pip安装pandas报标题这样的错,主要是因为python默认编码格式是:ascii

    在https://www.python.org/dev/peps/pep-0100/文章中有如下介绍

    Unicode Default Encoding

        The Unicode implementation has to make some assumption about the
        encoding of 8-bit strings passed to it for coercion and about the
        encoding to as default for conversion of Unicode to strings when
        no specific encoding is given.  This encoding is called <default
        encoding> throughout this text.
    
        For this, the implementation maintains a global which can be set
        in the site.py Python startup script.  Subsequent changes are not
        possible.  The <default encoding> can be set and queried using the
        two sys module APIs:
    
          sys.setdefaultencoding(encoding)
            --> Sets the <default encoding> used by the Unicode implementation.
                encoding has to be an encoding which is supported by the
                Python installation, otherwise, a LookupError is raised.
    
                Note: This API is only available in site.py!  It is
                removed from the sys module by site.py after usage.
    
          sys.getdefaultencoding()
            --> Returns the current <default encoding>.
    
        If not otherwise defined or set, the <default encoding> defaults
        to 'ascii'.  This encoding is also the startup default of Python
        (and in effect before site.py is executed).
    
        Note that the default site.py startup module contains disabled
        optional code which can set the <default encoding> according to
        the encoding defined by the current locale.  The locale module is
        used to extract the encoding from the locale default settings
        defined by the OS environment (see locale.py).  If the encoding
        cannot be determined, is unknown or unsupported, the code defaults
        to setting the <default encoding> to 'ascii'.  To enable this
        code, edit the site.py file or place the appropriate code into the
        sitecustomize.py module of your Python installation.



    解决方法:在python/lib/site.py中加入  

    import sys
    reload(sys)
    sys.setdefaultencoding('gbk')

    问题就解决了。。。。。。。。。。。。
