我将首先声明我已经搜索过这个问题，并在这里找到了完全相同的问题(ImportError: No module named 'requests')，但这对我没有帮助。在
我在osx(山狮)上使用macports。我已经成功地安装并运行了一些脚本，没有任何问题。在
从macports页面，我已经通过它详细介绍的方法安装了requests，据我所知，它已经成功安装：daves-mbp:~ Dave$ port search requests
arpwatch @2.1a15 (net)
Monitor ARP & RARP requests
http_ping @29jun2005 (net, www)
Sends HTTP requests every few seconds and times how long they take
httping @2.0 (net, www)
Ping-like tool for http-requests
py-requests @1.2.3 (python, devel)
Python HTTP for Humans.
py26-requests @1.2.3 (python, devel)
Python HTTP for Humans.
py27-requests @1.2.3 (python, devel)
Python HTTP for Humans.
py31-requests @1.2.3 (python, devel)
Python HTTP for Humans.
py32-requests @1.2.3 (python, devel)
Python HTTP for Humans.
py33-requests @1.2.3 (python, devel)
Python HTTP for Humans.
webredirect @0.3 (www)
small webserver which redirects all requests
Found 10 ports.
我有python 2.7，因此我通过以下方式安装它：
^{pr2}$
我觉得这看起来不错。在使用macports之前，我还需要做些什么吗？我认为python setup.py install(在前面提到的文章中)可能已经解决了我的问题，但是，当我在我的文件系统中搜索requests时，唯一的引用被隐藏在一个路径中(macports说这是用户安装的模块的存储)。而且，没有设置.py或者它的父目录中。在
我重新启动了我的终端窗口(之前解决了另一个问题)，但在这里没有什么不同。在
感谢任何帮助
编辑：
which python报告/opt/local/bin/python
python解释器的第一行确实报告了：
daves mbp:~戴夫$python

达尔文上的[GCC 4.2.1兼容Apple Clang 4.0(tags/Apple/Clang-418.0.60)]
但现在我做了一些事情，它却以新的错误回应：daves-mbp:~ Dave$ python
