python为什么numpy找不到_python找不到numpy

现在&＃xff0c;当我输入哪个python时&＃xff0c;它显示/usr/local/bin/python。

但是&＃xff0c;当我输入pip install numpy

它显示Requirement already satisfied (use --upgrade to upgrade): numpy in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python.

因此&＃xff0c;它们似乎位于不同的目录中&＃xff0c;而且可能是我以前安装的numpy&＃xff0c;这使得pip一直告诉我它们已经安装。我想知道这有什么办法吗&＃xff1f;

更新&＃xff0c;我已尝试导入它。import numpy

Traceback (most recent call last):

File "", line 1, in

ImportError: No module named numpy

我也尝试卸载numpy并再次安装它。但是&＃xff0c;当我卸载它时。它仍然给我错误。applematoMacBook-Air:~ apple$ pip uninstall numpy

DEPRECATION: Uninstalling a distutils installed project (numpy) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

Uninstalling numpy-1.8.0rc1:

/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy-1.8.0rc1-py2.7.egg-info

Proceed (y/n)? y
