Windows上的SciPy與Python 2.7安裝問題

Question

想知道是否有人遇到過類似的問題並且已經有解決方案？使用Windows 7

     - `pip install scipy` (last SciPy release on PyPI)

Answer 1

一些軟件包，如SciPy的，需要使用PIP建立一個編譯器。 Windows沒有附帶一個編譯器，所以你需要下載一個scipy的二進制文件，Windows可以使用。

來自加州大學歐文分校的一位名叫克里斯托弗·戈爾克的精彩男人爲Windows開發了這些二進制文件。你可以找到它們here。

注意：如果您沒有安裝Numpy，則無法安裝SciPy。你還需要下載Numpy Binary（還發現here）。只需按照隨後的步驟下載numpy模塊，就像下載scipy模塊一樣。

您安裝哪個鏈接取決於您是否擁有64位或32位版本的python，如果您已將它安裝到PATH上，您可以在命令行上使用python命令進行檢查。這裏是可視化的：

C:\Users\Bobby>python 
Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec 5 2015, 20:40:30) [MSC v.1500 64 bit (AMD64)] on win32 

你可以在括號中找到你的版本。正如你所看到的，我正在運行一個64位版本的python。因此，我將下載「scipy-0.18.0-cp27-cp27m-win_amd64.whl」文件，該文件假定我在64位版本的python上運行python 2.7（由ycp27表示）（由amd64表示）。

注意：還要確保點更新。您可以使用以下命令來更新它：

C:\Users\Bobby\Downloads>pip install --upgrade pip 

一旦SciPy的二進制下載，改變你的工作目錄到您的下載文件夾，運行點子，但使用.whl文件在您的下載。這是它可視化：

C:\Users\Bobby>cd Downloads 
C:\Users\Bobby\Downloads>pip install scipy-0.18.0-cp27-cp27m-win_amd64.whl 
Processing c:\users\bobby\downloads\scipy-0.18.0-cp27-cp27m-win_amd64.whl
