markupsafe._compat出错的解决办法

在windows下用pip进行安装的flask和freeze会在运行程序的时候出现报错

markupsafe._compat出错，那么此时找到对应的pip文件夹下自己创建一个_compat.py

然后复制下边的一段代码。

# -*- coding: utf-8 -*-
"""
    markupsafe._compat
    ~~~~~~~~~~~~~~~~~~
    Compatibility module for different Python versions.

"""
import sys
PY2 = sys.version_info[0] == 2
if not PY2:
    text_type = str
    string_types = (str,)
    unichr = chr
    int_types = (int,)
    iteritems = lambda x: iter(x.items())
else:
    text_type = unicode
    string_types = (str, unicode)
    unichr = unichr
    int_types = (int, long)
    iteritems = lambda x: x.iteritems()

然后再次运行程序就可以正常启动flask的程序了。
