您好，我正在尝试安装python-twitter，其中一个依赖项HTTPLIB2给我带来了很多问题。我在互联网上上下搜索过，但也许我不知道正确的关键词是什么。这是问题所在。

我正在安装python-twitter. "pip install -r requirements.txt"例如，我通过安装或一一安装要求"pip install httplib2"。然后我跑"python setup.py install"。它很高兴，但随后"python setup.py test"失败，并出现错误import HTTPLIB2。

python setup.py test

    print('%s:' % h, end=' ', file=self._fp)
                    ^
SyntaxError: invalid syntax

但我认为打印错误是 python 2 和 3 之间的不兼容。为什么我得到这个，而我显然有 python 2.7（我检查并卸载并重新安装了 HTTPLIB2）。非常感谢您的帮助

我有同样的问题。似乎是 python2.7 和 3.x 版本冲突问题，由

python2.7 -m pip install -t lib/ -r requirements.txt

Just in case, this happens when you install httplib2 with a python3 version of pip and then execute it with python2.

This happens for example when creating manually an environment with:

pip install -t lib/ -r requirements

As it happens when creating an AppEngine standard environment vendor folder.

This happens because contrary to most of the libraries, httplib2 has completely different versions for python2 and python3.
