我无法测试运行我想使用的 cssparser。
测试.py:
from css.parse import parse
data = """
em {
padding: 2px;
margin: 1em;
border-width: medium;
border-style: dashed;
line-height: 2.4em;
}
p { color: red; font-size: 12pt }
p:first-letter { color: green; font-size: 200% }
p:first-line { color: blue }"""
for rule in parse(data):
print (rule)
..给出一个错误:
Traceback (most recent call last):
method <module> in test.py at line 1
from css.parse import parse
method <module> in test.py at line 6
from . import css, csslex, cssyacc
method <module> in test.py at line 8
from . import serialize
method <module> in test.py at line 6
from . import css
ImportError: cannot import name css
目录结构(/Users/nimbuz/Documents/python31):
/Users/nimbuz/Documents/python31/**csspy**/
|
+-- css/ (*has __init__.py*)
|
+-- uri/ (*has __init__.py*)
|
+-- test.py
print(sys.path) 显示:
['/Users/nimbuz/Documents/python31/csspy', '/Library/Frameworks/Python.framework/Versions/3.1/lib/python31.zip', '/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1', '/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/plat-darwin', '/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/lib-dynload', '/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/site-packages']
请您参考如下方法:
这是我刚刚测试的几个步骤。
readme说是python 2.5,所以需要python 2.x系列
我已经创建了一个文件夹
C:/TEST/我已经从 css-py svn 下载了所有文件到
C:/TEST/,所以C:/TEST/css/和C:/TEST/uri/文件夹现在存在。我已经下载了ply's tar gz file并将仅
ply文件夹提取到C:/TEST/css/中,所以C:/TEST/css/ply/文件夹现在存在。我已经在
C:/TEST/中创建了test.py内容from css.parse import parse print dir(parse)我运行它,结果是这样的,没有导入错误:
C:\TEST>test.py['__call__', '__class__', '__closure__', '__code__', '__defaults__', '__delattr__', '__dict__', '__doc__', '__format__', '__get__', '__getattribute__' , '__globals__', '__hash__', '__init__', '__module__', '__name__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', ' __subclasshook__', 'func_closure', 'func_code', 'func_defaults', 'func_dict', 'func_doc', 'func_globals', 'func_name']
希望这对您有所帮助。对不起,如果我的解释不好。
