[英]Numpy module missing in Python3 installation
I have installed the Python 3 on my Windows 10 OS. 我在Windows 10操作系统上安装了Python 3。 Everything seemed fine. 一切似乎都很好。 I have run some tkinter programs and they are all working fine. 我已经运行了一些tkinter程序,它们都运行良好。
I now wanted to use the numpy
module for achieving a task and to my amusement I see there is no Numpy module in the Python I have installed. 我现在想使用numpy
模块来实现任务,而且我觉得我已经安装的Python中没有Numpy模块。
I learnt that numpy module is a basic madule that should come with the python installation. 我了解到numpy模块是python安装应该附带的基本模块。 Am I correct on this? 我对此是否正确? If not, how can I install numpy now? 如果没有,我现在如何安装numpy?
I tried installing with pip ( pip install -U numpy
) as suggested by one of the answers to a question in stackoverflow (3rd answer to this question - Installing SciPy with pip ) but when I do I get an error: 我尝试使用pip( pip install -U numpy
)进行pip install -U numpy
如stackoverflow中的一个问题的答案所示(此问题的第3个答案 - 使用pip安装SciPy )但是当我这样做时出现错误:

Well, as you can see, you need Microsoft Visual C++: 好吧,正如您所看到的,您需要Microsoft Visual C ++:
error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat).
This is because pip
is trying to compile NumPy. 这是因为pip
正在尝试编译NumPy。 Compiling packages might be not so easy, specially if you are using Windows... 编译包可能不是那么容易,特别是如果你使用Windows ...
But there is an alternative to pip
, which you may find very convenient: Conda . 但是有一个替代pip
,你可能会觉得非常方便: Conda 。
