Python Pip安裝：在命令提示符窗口中未被識別為批處理文件…

Question

我有一個項目，需要安裝numpy。

我今天早上才將Python 2.7.11下載到我的Windows 10計算機上，並且自下載以來沒有在2.7.11安裝中使用pip或其他任何東西。

我沒有在安裝2.7.11中移動任何文件。

我打開命令提示符並鍵入

pip install numpy

並得到錯誤：

 pip is not recognized as an internal or external command, operable program or batch file

接下來，我輸入：

cd C:\Python27\Scripts

進入命令提示符。 它過去了，我再次鍵入：

pip install numpy

而且它工作了一段時間，下載numpy沒有問題。 然后：

C:\Python27\Scripts>pip install numpy

這實際上是我重試安裝的時間，這就是為什么一開始它說“使用緩存的numpy-1.10.2.tar.gz”的原因

我不知道所有的錯誤是什么意思，但是我在某處（無法找到的地方，所以我無法給出鏈接）看到一篇文章，該文章說通過在命令提示符下鍵入來安裝pip：

python get-pip.py

或類似的內容。（正如我所說，無法重新找到該文章）

並得到此錯誤：

"python" is not recognized as an internal or external command, operable program or batch file

任何幫助將是巨大的！ 如果您有一種無需點子即可下載numpy的方法，那就太好了，但是我還需要獲取其他一些模塊，我真的很想讓點子開始工作。 另外，我的互聯網非常糟糕，這有助於避免下載大文件。

謝謝

Answer 1

有3種方法可以解決此問題。

1. 您忘記了執行C:/Python27/python get-pip.py 。 您記得為pip這樣做，但是您放棄了python get-pip.py 。

2. 另外，您需要C ++，它在錯誤的最后一行說。 error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from http://aka.ms/vcpython27 error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from http://aka.ms/vcpython27 。 如此說來，請獲取Visual C ++。 沒有它，點子就無法工作。

3. 如果總是輸入C:/Python27/python和C:/Python27/Scripts/pip您，請編輯PATH環境變量。 你可以谷歌。 進入后，輸入目錄（例如C:/Python27/python ）。 所有目錄都用分號分隔。

如果這完全有幫助，請添加+1！
