在Python3中安装motionless1.1后，运行

import motionless

系统报错：

Traceback (most recent call last):  File "<pyshell#2>", line 1, in <module>    import motionless  File "<frozen importlib._bootstrap>", line 2237, in _find_and_load  File "<frozen importlib._bootstrap>", line 2222, in _find_and_load_unlocked  File "<frozen importlib._bootstrap>", line 2164, in _find_spec  File "<frozen importlib._bootstrap>", line 1940, in find_spec  File "<frozen importlib._bootstrap>", line 1916, in _get_spec  File "<frozen importlib._bootstrap>", line 1897, in _legacy_get_spec  File "<frozen importlib._bootstrap>", line 863, in spec_from_loader  File "<frozen importlib._bootstrap>", line 904, in spec_from_file_location  File "C:\Python34\lib\site-packages\motionless-1.1-py3.4.egg\motionless.py", line 55    if label and (len(label) <> 1 or not label in Marker.LABELS):                              ^SyntaxError: invalid syntax

原因是motionless的版本虽然为motionless-1.1-py3.4,但其中很多语法仍然没有更新。

修正方法：

从C:\Python34\Lib\site-packages中找到motionless-1.1-py3.4.egg，用解压缩软件打开，找到其中的motionless.py，再用编辑软件或记事本打开，修改以下几行：

1、第1行 quote,改为parse

from urllib import parse

2、第55行和第190行中的<>改为！=

if label and (len(label) != 1 or not label in Marker.LABELS):

if self.region and self.path[0] != self.path[-1]:

3、调整第178、179、196行的缩进，与前文保持8个空格（英文模式下）

        self.markers = []        self.fillcolor = fillcolor        self.pathweight = pathweight        self.pathcolor = pathcolor        self.region = region        self.path = []

        if self.region and self.path[0] != self.path[-1]:             raise ValueError("If region enabled, first and last path entry must be identical")        if len(self.path) == 0 and len(self.markers) == 0:            raise ValueError("Must specify points in path or markers")        if not Color.is_valid_color(self.fillcolor):            raise ValueError("%s is not a valid fill color. Must be 24 or 32 bit value or one of %s" % (self.fillcolor,Color.COLORS))

4、文中所有的quote更正为parse.quote
