无法在Windows 10中安装软件包 [英] Can't install packages in Windows 10

问题描述

我刚刚重新安装了Python 3.6，但是当我尝试安装软件包时，Windows返回错误.首先，我尝试从Windows命令提示符安装软件包BeautifulSoup:

I just reinstalled Python 3.6, but when I try to install packages, Windows returns errors. First I tried installing package BeautifulSoup from the Windows command prompt:

python -m pip install BeautifulSoup

但这会返回以下错误:

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\

然后我尝试安装软件包requests:

Then I tried installing package requests:

python -m pip install requests

但这会返回

我需要做什么才能使pip成功安装软件包?

What do I need to do so that pip successfully installs packages?

推荐答案

BeautifulSoup仅适用于Python 2.对于Python 3，安装 beautifulsoup4 :

BeautifulSoup is for Python 2 only. For Python 3 install beautifulsoup4:

pip install beautifulsoup4

第二个问题似乎很明显:您没有对C:\\Program Files\\Python36\\Lib\\site-packages和子目录的写访问权.

The second problem seems obvious: you don't have write-access to C:\\Program Files\\Python36\\Lib\\site-packages and subdirectories.
