BeautifulSoup的安装

在windows上安装步骤如下：
 
1. 对于python2.7，在官网上下载 BeautifulSoup4-4.1.0，（经试验，4-4.3.2不能安装成功）
2. 解压缩到本地硬盘，比如C:\Python27目录下
3. 运行cmd，输入命令：
      setup.py build
      setup.py install
4. 然后可以在 IDE中输入import BeautifulSoup 或者 from BeautifulSoup import BeautifulSoup ，没报错则安装成功
 
在mac上安装步骤如下：
 
1. 在官网上下载BeautifulSoup4-4.3.2，解压（解压到哪里都无所谓）
2. cd 进入刚解压的文件夹路径下，输入命令：
       python setup.py install
3. 然后可以看到，输入import bs4，在iTerm(python)和PyCharm、sublime text3都可以正常使用。但是在spyder上却报错，找不到bs4这个module模块。于是分别查看这四个界面中，python代码：
      import sys
      print sys.path
在iTerm中出现（pycharm和sublime text3类似）：
>>> import sys>>> sys.path[‘‘, ‘/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip‘, ‘/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7‘, ‘/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin‘, ‘/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac‘, ‘/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages‘, ‘/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python‘, ‘/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk‘, ‘/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old‘, ‘/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload‘, ‘/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC‘, ‘/Library/Python/2.7/site-packages‘]

然而spyder显示：

import syssys.pathOut[2]: [‘‘, ‘/Applications/Spyder.app/Contents/Resources/lib/python2.7/spyderlib/utils/external‘, ‘/Library/Python/2.7/site-packages‘, ‘/Applications/Spyder.app/Contents/Resources‘, ‘/Applications/Spyder.app/Contents/Resources/lib/python27.zip‘, ‘/Applications/Spyder.app/Contents/Resources/lib/python2.7‘, ‘/Applications/Spyder.app/Contents/Resources/lib/python2.7/plat-darwin‘, ‘/Applications/Spyder.app/Contents/Resources/lib/python2.7/plat-mac‘, ‘/Applications/Spyder.app/Contents/Resources/lib/python2.7/plat-mac/lib-scriptpackages‘, ‘/Applications/Spyder.app/Contents/Resources/lib/python2.7/lib-tk‘, ‘/Applications/Spyder.app/Contents/Resources/lib/python2.7/lib-old‘, ‘/Applications/Spyder.app/Contents/Resources/lib/python2.7/lib-dynload‘, ‘/Applications/Spyder.app/Contents/Resources/lib/python2.7/site-packages.zip‘, ‘/Applications/Spyder.app/Contents/Resources/lib/python2.7/site-packages‘, ‘/Applications/Spyder.app/Contents/Resources/lib/python2.7/IPython/extensions‘, ‘/Users/jyy/.ipython‘]

安装的package放在/Library/Python/2.7/site-packages目录下，进入可以看到bs4的文件夹（主要是.pyc和.py文件）。然而spyder默认的路径则不在这目录下，解决办法是在spyder的PYTHONPATH manager 中加入该路径即可。
