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。
我在 osx（山狮）上使用 macports。我已经成功安装并运行了一些脚本，没有任何问题。
从 macports 页面，我已经requests通过详细说明的方法进行了安装，据我所知，它已成功安装：
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，所以我通过以下方式安装了它：
daves-mbp:~ Dave$ sudo port install py27-requests

daves-mbp:~ Dave$
我认为这看起来不错。使用 macports 在使用它之前我还需要做些什么吗？我认为python setup.py install（在上述帖子中）可能已经解决了我的问题，但是，当我requests在我的文件系统中搜索时，唯一的引用被埋在路径中（macports 说是用户安装模块的商店。此外，还有其中没有 setup.py 或其父目录。
我已经重新启动了我的终端窗口（之前解决了另一个问题），但在这里没有任何区别。
任何帮助表示赞赏
编辑：
which python报告 /opt/local/bin/python

但现在我已经做了一些事情，它正在响应新的错误：
