Anaconda:UnicodeDecodeError

Win10下安装Anaconda for python2.7，启动Anaconda Prompt时候出现以下错误：

UnicodeDecodeError: 'ascii' codec can't decode byte 0xa3 in position 0: ordinal not in range(128)

从最后的错误信息来看，是解码不对。解决方案如下：
从报错的第一行找到对应的文件：conda-script.py（运行conda env list的时候发生类似错误，不过报错的文件变成conda-env-script.py，解决方案相同），将其内容改为：

if __name__ == '__main__':
    import sys
    if sys.getdefaultencoding() != 'gbk':  
        reload(sys)  
        sys.setdefaultencoding('gbk')      
    import conda.cli
    sys.exit(conda.cli.main())
