如果要在windows上请求导入：

pip install request

然后美容组4：

pip3 install beautifulsoup4

我已经安装了python2.7和python3.6

打开命令行~/.bash_profile，我发现#Setting PATH for Python 3.6，所以我将路径更改为path=“/usr/local/Cellar/python/2.7.13/bin:${path}”，（请确保您的python2.7路径），然后保存。这对我有用。

如果你使用的是水蟒步骤1：其中python步骤2：以管理员模式打开anaconda提示符步骤3：cd＜python路径＞步骤4：在此位置安装软件包

尽管我安装了几次“requests”，但还是出现了同样的错误。问题是我在全局Python环境中安装请求，而不是在应用程序虚拟环境中。在虚拟环境中安装请求后，错误消失了。因此，这里有一篇关于如何在应用程序虚拟环境中安装“请求”的好书：虚拟环境和软件包

这可能有点太晚了，但即使未设置pip路径，也可以运行此命令。我使用的是在Windows 10上运行的Python 3.7，这是命令

py -m pip install requests

您还可以用任何其他未安装的库替换“requests”
