Python3安装中缺少Numpy模块

Question

我在Windows 10操作系统上安装了Python 3。一切似乎都很好。我运行了一些tkinter程序，它们都工作正常。

我现在想使用numpy模块来完成一项任务，而我的娱乐我发现我已经安装了Python中没有Numpy模块。

我了解到numpy模块是一个基本的应用程序，它应该与python安装一起提供。我对此是否正确？如果没有，我现在怎么安装numpy？

我试着用PIP（pip install -U numpy）安装在回答一个问题在计算器中的一个（3回答这个问题 - Installing SciPy with pip）的建议，但是当我做我得到一个错误：

Answer 1

好正如你所看到的，你需要的Microsoft Visual C++：

error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat). 

这是因为pip试图编译NumPy的。编译软件包可能并不那么容易，特别是如果您使用的是Windows ...

但是有一种替代pip，您可能会发现非常方便：Conda。

看一看的文档，看看你可以轻松地：

• 创建虚拟环境中使用你喜欢的Python解释器。
• 安装已经编译好的Python软件包（当然包括NumPy）。
• 安装非科学Python包，这可能不需要编译（用纯Python编写）。
