在Microsoft Visual Studio 2013中沒有名爲flask的模塊

當我運行一個新的（沒有任何修改的新鮮創建）Flask Web Project在Visual Studio中不能編譯。我收到一個錯誤「No module named flask」。這對我來說毫無意義，因爲它是我創建的一個「Flask」項目，我沒有做任何事情來打破它。微軟是否可能爲新的Flask項目提供了不完整的模板？我很困惑。在Microsoft Visual Studio 2013中沒有名爲flask的模塊

當我嘗試添加一個虛擬的環境中，我得到以下日誌：

的「瓶項目」使用PowerShell可能只是創建一些目錄/文件的模板，您仍然必須創建virtualenv並安裝要使用的庫（包括Flask）。 – davidism 2014-10-29 06:07:10

請看微軟的[本指南]（https://pytools.codeplex.com/wikipage?title=Flask）。 – dirn 2014-10-29 12:12:36

謝謝@dim。我嘗試添加一個虛擬環境，但它不工作，我在其他線程上看到了一些「不」使用它的評論。我不清楚任何一種選擇的全部影響，所以我現在編輯我的帖子來添加添加虛擬環境的日誌結果。最明顯的結論是pip沒有正確安裝，但是，我試圖依靠MSVS來照顧所有這些，因爲我對Python沒有經驗。有什麼建議麼？ – DSMagic 2014-10-29 23:36:25
