FileNotFoundError，但邻居文件可以找到它

Question

正在尝试使用Cisco confparse。我有两个.py文件和两个.txt文件。一个python文件可以解析两个.txt文件，而另一个文件在解析两个.txt文件时获得FileNotFoundError。所有文件都位于相同的位置：

/Users/christian/Desktop/Networking/Testing//test.py
/Users/christian/Desktop/Networking/Testing//test2.py
/Users/christian/Desktop/Networking/Testing//exampleSwitch.txt
/Users/christian/Desktop/Networking/Testing//exampleSwitch2.txt

test.py的工作方式：

from ciscoconfparse import CiscoConfParse

# Parse the config into objects
confprse = CiscoConfParse('exampleSwitch.txt')

# Iterate over all the interface objects
for intf_obj in confprse.find_objects('^interface'):
    print("cisconfparse object: ")
    print(intf_obj)
    print(intf_obj.text)

而test2.py并非如此：

from ciscoconfparse import CiscoConfParse


confprse = CiscoConfParse('exampleSwitch2.txt')

错误是：

[FATAL] CiscoConfParse could not open 'exampleSwitch2.txt'
Traceback (most recent call last):
  File "/Users/christian/Desktop/Networking/Testing/venv/lib/python3.8/site-packages/ciscoconfparse/ciscoconfparse.py", line 233, in __init__
    f = open(config, **self.openargs)
FileNotFoundError: [Errno 2] No such file or directory: 'exampleSwitch2.txt'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/christian/Desktop/Networking/Testing/test2.py", line 4, in <module>
    confprse = CiscoConfParse('exampleSwitch2.txt')
  File "/Users/christian/Desktop/Networking/Testing/venv/lib/python3.8/site-packages/ciscoconfparse/ciscoconfparse.py", line 308, in __init__
    raise RuntimeError
RuntimeError

不确定问题出在哪里。
