無法在Windows 10中安裝軟件包

我剛剛重新安裝了Python 3.6，但是當我嘗試安裝軟件包時，Windows會返回錯誤。首先我想從Windows命令提示符下安裝包BeautifulSoup：無法在Windows 10中安裝軟件包

python -m pip install BeautifulSoup

但這返回以下錯誤：

Collecting BeautifulSoup 
    Using cached BeautifulSoup-3.2.1.tar.gz 
    Complete output from command python setup.py egg_info: 
    Traceback (most recent call last): 
     File "<string>", line 1, in <module> 
     File "C:\Users\Robert\AppData\Local\Temp\pip-build-iiyyxs2o\BeautifulSoup\setup.py", line 22 
     print "Unit tests have failed!" 
            ^
    SyntaxError: Missing parentheses in call to 'print' 

    ---------------------------------------- 
Command "python setup.py egg_info" failed with error code 1 in C:\Users\Robert\AppData\Local\Temp\pip-build-iiyyxs2o\BeautifulSoup\

然後我試圖安裝包requests：

python -m pip install requests

但這種回報

我需要做什麼才能讓pip成功安裝軟件包？

您可以嘗試：使用_elevated privileges_（管理員）運行命令提示符。然後使用'pip install beautifulsoup'（小寫）;並重試'請求'以及應該工作 –

@ Jean-FrançoisFabre在管理命令提示符下，Windows在'pip install beautifulsoup'後報告相同的錯誤' – Robert

'request'怎麼辦？ –

BeautifulSoup僅適用於Python 2。對於Python 3安裝beautifulsoup4：

pip install beautifulsoup4

第二個問題似乎很明顯：你沒有寫訪問C:\\Program Files\\Python36\\Lib\\site-packages和子目錄。

不那麼明顯。你如何解決這個問題？ –

將Python安裝到用戶具有寫入權限的目錄中。 C：\\ Python36是最標準的地方。 – phd

或以提升的權限運行命令提示符。 –
