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。 我已经运行了一些tkinter程序，它们都运行良好。

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。

我了解到numpy模块是python安装应该附带的基本模块。 我对此是否正确？ 如果没有，我现在如何安装numpy？

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：

Answer 1

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).

这是因为pip正在尝试编译NumPy。 编译包可能不是那么容易，特别是如果你使用Windows ...

但是有一个替代pip ，你可能会觉得非常方便： Conda 。

查看文档并了解如何轻松：

• 创建虚拟环境以使用您喜欢的Python解释器。
• 安装已经为你编译的科学Python包（当然包括NumPy）。
• 安装非科学的Python包，可能不需要编译（用纯Python编写）。
