我开始使用Apache AGE python驱动程序并学习它，目前我正在探索GitHub上提供的示例，所以我决定继续使用在线jupyter平台进行测试[google-colab]是选定的一个，我遵循安装指南，以便在我的笔记本开始时，我在运行时中使用以下命令安装驱动程序：

!sudo apt-get update
!sudo apt-get install python3-dev libpq-dev
!git clone https://github.com/apache/age.git
!cd age/drivers/python && pip3 install -r requirements.txt && python3 setup.py install

成功安装但每当我尝试使用它

# Not working
import age
import unittest
from decimal import Decimal

resultHandler = age.newResultHandler()
    
def evalExp(exp):
    value = resultHandler.parse(exp) 
    print(type(value), "|", exp, " --> " ,value )
    
mapStr = '{"name": "Smith", "num":123, "yn":true, "bigInt":123456789123456789123456789123456789::numeric}' 

evalExp(mapStr)

Output（所有方法输出相同，模块没有属性）

AttributeError                            Traceback (most recent call last)

<ipython-input-38-053b6cdde8b8> in <cell line: 6>()
      4 from decimal import Decimal
      5 
----> 6 resultHandler = age.newResultHandler()
      7 
      8 def evalExp(exp):

AttributeError: module 'age' has no attribute 'newResultHandler'

另一方面，当我决定直接从源代码导入时，它可以正常工作

# Working
import age.drivers.python.age as age
import unittest
from decimal import Decimal

resultHandler = age.newResultHandler()
    
def evalExp(exp):
    value = resultHandler.parse(exp) 
    print(type(value), "|", exp, " --> " ,value )
    
mapStr = '{"name": "Smith", "num":123, "yn":true, "bigInt":123456789123456789123456789123456789::numeric}' 

evalExp(mapStr)

输出

<class 'dict'> | {"name": "Smith", "num":123, "yn":true, "bigInt":123456789123456789123456789123456789::numeric}  -->  {'name': 'Smith', 'num': 123, 'yn': True, 'bigInt': Decimal('123456789123456789123456789123456789')}
