我安装了Twilio：
pip3 install twilio
但是它将仅在Python 3 Applications文件夹中运行。
// ♥ python3
Python 3.7.1 (v3.7.1:260ec2c36a, Oct 20 2018, 03:13:28)
[Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more
information.
>>> import twilio
>>> print(twilio.__version__)
6.21.0
这是我从其他任何文件夹中获得的信息：

>>> import twilio
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/davidtannenbaum/Dropbox (Personal)/pythonpractice/twilio.py", line 2, in <module>
print(twilio.__version__)
AttributeError: module 'twilio' has no attribute '__version__'
任何人都知道为什么它可以在Python 3.7目录中工作并在其他任何地方给出错误吗？我该如何解决？
