python - 导入 Pyshark 时遇到问题

Question

我在 OS X 10.10 上使用 Pyshark 和 Python 2.6。我只是尝试在代码中导入 pyshark，然后抛出此错误。知道可能出了什么问题吗？

/System/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6 "/Users/spencergardner/Google Drive/development/python-sockets/sniff.py"

SyntaxError: invalid syntax

Answer 1

该错误是由于使用 dictionary comprehension ，一个语言功能是 introduced to Python 2 in 2.7 ，而不是您尝试使用的 2.6。 Apple 发布了 OS X 10.10 以及 2.7 和 2.6。有什么理由不能使用 2.7 来代替吗？
