如何导入模块uno？

Question

python3
Python 3.9.6 (default, Jul 14 2021, 09:15:03) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import uno
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.9/site-packages/uno/__init__.py", line 4, in <module>
    from base import Element, Css, Payload, UnoBaseFeature, UnoBaseField
ImportError: cannot import name 'Element' from 'base' (/usr/local/lib/python3.9/site-packages/base/__init__.py)
>>> 

检查uno中的文件

ls  /usr/local/lib/python3.9/site-packages/uno
base.py  constants.py  core.py  css_constants.py  decorators.py  field.py  form.py  helpers.py  __init__.py  input_elements.py  __pycache__  quickadder.py  search.py

它在文件中为空

ls -al /usr/local/lib/python3.9/site-packages/base/__init__.py
-rw-r--r-- 1 root root 0 Jun 23  2016 /usr/local/lib/python3.9/site-packages/base/__init__.py

修复/usr/local/lib/python3.9/site-packages/uno/__init__.py中的行

from .base import Element, Css, Payload, UnoBaseFeature, UnoBaseField

再次重新导入：

python3
Python 3.9.6 (default, Jul 14 2021, 09:15:03) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import uno
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.9/site-packages/uno/__init__.py", line 4, in <module>
    from .base import Element, Css, Payload, UnoBaseFeature, UnoBaseField
  File "/usr/local/lib/python3.9/site-packages/uno/base.py", line 129
    print 'new css', self._attr, 'value:', value
          ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print('new css', self._attr, 'value:', value)?

模块uno是用python2编写的。 现在安装python3支持的uno
