Python - 安装第三方

环境:mac 终端

安装pip 输入命令： easy_install pip
安装到python2.7：pip install beautifulsoup4
安装到python3： pip3 install beautifulsoup4
其他库也是同理

这里举个特殊的🌰: pip3 install lxml

  Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?
Perhaps try: xcode-select --install
(原谅我不知道怎么换行😂)*********************************************************************************
error: command '/usr/bin/clang' failed with exit status 1

----------------------------------------
Command "/Library/Frameworks/Python.framework/Versions/3.6/bin/python3.6 -u -c "import setuptools, tokenize;__file__='/private/var/folders/_g/86nkv4gj1n73jq7qjqzvtqgc0000gn/T/pip-build-e9lbyjew/lxml/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /var/folders/_g/86nkv4gj1n73jq7qjqzvtqgc0000gn/T/pip-i49olh35-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /private/var/folders/_g/86nkv4gj1n73jq7qjqzvtqgc0000gn/T/pip-build-e9lbyjew/lxml/

这时你需要在终端输入:

 xcode-select --install

安装成功后再:
