Python3安裝中缺少Numpy模塊

Question

我在Windows 10操作系統上安裝了Python 3。一切似乎都很好。我運行了一些tkinter程序，它們都工作正常。

我現在想使用numpy模塊來完成一項任務，而我的娛樂我發現我已經安裝了Python中沒有Numpy模塊。

我瞭解到numpy模塊是一個基本的應用程序，它應該與python安裝一起提供。我對此是否正確？如果沒有，我現在怎麼安裝numpy？

我試着用PIP（pip install -U numpy）安裝在回答一個問題在計算器中的一個（3回答這個問題 - Installing SciPy with pip）的建議，但是當我做我得到一個錯誤：

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). 

這是因爲pip試圖編譯NumPy的。編譯軟件包可能並不那麼容易，特別是如果您使用的是Windows ...

但是有一種替代pip，您可能會發現非常方便：Conda。

看一看的文檔，看看你可以輕鬆地：

• 創建虛擬環境中使用你喜歡的Python解釋器。
• 安裝已經編譯好的Python軟件包（當然包括NumPy）。
• 安裝非科學Python包，這可能不需要編譯（用純Python編寫）。
