## Python3.7.0 安装beautifulsoup4 4.6.3 ##

打开cmd，然后在cmd中输入命令“pip install beautilfulsoup4”

发现pip有新版本，按提示更新pip。（pip在文章后有解释）

然后在cmd中输入命令“pip install beautilfulsoup4”

还是没匹配到bs4

去python官网搜bs4的安装包，（python的官网提供第三方模块）

我下载最新版本的beautifulsoup4

下载完成后，我把安装包解压到安装python的目录下，通过cmd进入到该安装包解压后的文件夹目录下。在该文件目录下输入"python setup.pyinstall"，进行beautilfulsoup4模块的安装，当安装完成后会看到有"Finished"字样

安装完成后，在cmd中运行Python,然后输入"from bs4 import BeautifulSoup" 导入该模块，如果成功安装的话将没有任何打印信息，否则会有相应的错误信息打印。

ps1:

pip 是一个现代的，通用的 Python 包管理工具\[1\]。提供了对Python 包的查找、下载、安装、卸载的功能。

官方提供的pip 示例

$ pip install requests

$ pip search xml

$ pip show beautifulsoup4

$ pip uninstall requests

ps2:

一些参考教程中有很多坑，比如命令“form bs4 import BeautilfulSoup”都不给正确的。所以写一个做笔记用。
