python 学习

安装的是python 3.3 http://www.python.org/ftp/python/3.3.5/python-3.3.5.amd64.msi ‘Python’ 不是内部或外部命令，也不是可运行的程序或批处理文件。需要手动添加环境变量：鼠标右键我的电脑 -> 属性 -> 点击高级系统设置 -> 点击环境变量 -> 点击PATH -> 在最后面加上我们的Python安装路径 -> 点击确定。在这个过程中需要注意的问题是，添加PATH路径的时候，要在最后面添加一个分号。下载pip-8.1.2.tar.gz至Python安装目录，解压用CMD控制台进入解压目录 python setup.py install 显示 ImportError: No module named ‘setuptools’ 下载https://bootstrap.pypa.io/ez_setup.py C:\ChromeDL python ez_setup.py 再试一次 pip安装成功了 ‘pip’ 不是内部或外部命令，也不是可运行的程序或批处理文件。按照之前介绍的添加环境变量的方法，我们在PATH最后添加： C:\Python33\Scripts; 重启CMD，到现在才算完整安装好了pip。 pip install BeautifulSoup4 LDLE里面 import bs4 没有报错。
