我用pip來安裝請求，但是當我運行我的scrpit時，我得到一個導入錯誤。OSX上的Python請求
我也嘗試從github安裝，但仍然是同樣的問題。
這裏是輸出

osx:shane shane$ sudo -H pip install requests

我到底做錯了什麼？
的sys.path輸出
打印sys.path的
['', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/lxml-3.6.0-py2.7-macosx-10.6-intel.egg']
打印'import sys; sys.base_prefix'和'sys.path'，看看你是否使用了安裝了'requests'的python。 'pip'看起來像是'brew'版本，其次可能是系統版本。 – AChampion
'pip'在python的另一個實例中安裝'requests'。更新您的環境。 '哪個pip'，'哪個python'，改變你的路徑。研究虛擬環境（'virtualenv'）它將大大簡化事情。 – AChampion
