如何使用easy_install安裝熊貓？

Question

我在Windows 8和cmd上使用python 2.7.8我寫了easy_install pandas。經過一些處理後，它給了我一個錯誤，並要求我下載vcpython27。

在CMD：

這是完全不可理解。任何想法解決這個問題？

Answer 1

pandas（和其他各種python庫）使用C語言來執行一些繁重的工作。 Pip包通常在客戶端上下載和編譯C源代碼，而在* nix機器上，這通常是有編譯器的。但是，Windows不附帶編譯器默認值。所以，你的選擇是（從最難最容易）：

1. 安裝C編譯器（惱人的，如果你不這樣做，否則任何C）
2. 安裝像蟒蛇或enthought蟒蛇分佈，其採取的這些東西護理對你來說（這些很好很容易，但你可能已經有了一個你想要保留的定製的env）。
3. 使用輪安裝軟件包 - 這些是雞蛋的後繼產品，它們不需要在Windows上編譯。一些軟件包已經附帶輪子，但不是全部。然而，在http://www.lfd.uci.edu/~gohlke/pythonlibs/有非官方的車輪收集您可以下載車輪，並使用點安裝它。

編輯：建議@cel - 因爲上帝的緣故不要使用easy_install！改爲使用pip - 您需要的很多軟件包已經有可供pip查找的輪包。如果你還沒有點子，然後嘗試easy_install pip（就像使用Internet Explorer的唯一原因是使用它來下載另一個瀏覽器;）
