我是wubi安裝的ubuntu18.04，安裝的pgadmin4-3.0*.whl，安裝成功了。我使用python3.6.5的pip3安裝的，然后用python3運行pgadmin4.py。出現錯誤，如下：
-----------------------------------------------------------------------------------------------------------------------------------------------
hengaini2055@ubuntu:~/.local/lib/python3.6/site-packages/pgadmin4$ sudo python3 ./pgAdmin4.py
Traceback (most recent call last):
File "./pgAdmin4.py", line 70, in <module>
app = create_app()
File "/home/hengaini2055/.local/lib/python3.6/site-packages/pgadmin4/pgadmin/__init__.py", line 310, in create_app
schema_version = version.value
AttributeError: 'NoneType' object has no attribute 'value'
----------------------------------------------------------------------------------------------------------------------------------------------
請問這是怎么回事呢？
