我正在尝试安装 parsley,这是一个用 python 编写的解析器,但我遇到了第一个障碍。我什至无法安装它。我在 Windows 7 上,使用 cygwin。
而这个版本的python: $ python3 -V Python 3.4.2
$ pip install Parsley
Downloading/unpacking Parsley

Successfully installed Parsley
Cleaning up...
然后在python的IDLE中:
>>> import parsley
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
import parsley
File "C:\Python34\lib\site-packages\parsley.py", line 86
except ParseError, e:
^
SyntaxError: invalid syntax
我究竟做错了什么?
