Python: Install BeautifulSoup in Windows 8

Running Environment: Windows 8.1

Python: 2.7.6

During installation, I use pip for installation. The command is as follows:

Pip install beautifulsoup4

When running, the following error is reported:

Exception:Traceback (most recent call last):  File "J:\Program Files (x86)\Python\Python27\lib\site-packages\pip\basecomm.py", line 122, in main    status = self.run(options, args)  File "J:\Program Files (x86)\Python\Python27\lib\site-packages\pip\commandsstall.py", line 278, in run    requirement_set.prepare_files(finder, force_root_egg_info=self.bundle, bue=self.bundle)  File "J:\Program Files (x86)\Python\Python27\lib\site-packages\pip\req.py",ne 1229, in prepare_files    req_to_install.run_egg_info()  File "J:\Program Files (x86)\Python\Python27\lib\site-packages\pip\req.py",ne 292, in run_egg_info    logger.notify('Running setup.py (path:%s) egg_info for package %s' % (seletup_py, self.name))  File "J:\Program Files (x86)\Python\Python27\lib\site-packages\pip\req.py",ne 265, in setup_py    import setuptools  File "build\bdist.win-amd64\egg\setuptools\__init__.py", line 11, in <modul    from setuptools.extension import Extension  File "build\bdist.win-amd64\egg\setuptools\extension.py", line 5, in <modul  File "build\bdist.win-amd64\egg\setuptools\dist.py", line 15, in <module>  File "build\bdist.win-amd64\egg\setuptools\compat.py", line 19, in <module>  File "J:\Program Files (x86)\Python\Python27\lib\SimpleHTTPServer.py", line, in <module>    class SimpleHTTPRequestHandler(BaseHTTPServer.BaseHTTPRequestHandler):  File "J:\Program Files (x86)\Python\Python27\lib\SimpleHTTPServer.py", line8, in SimpleHTTPRequestHandler    mimetypes.init() # try to read system mime.types  File "J:\Program Files (x86)\Python\Python27\lib\mimetypes.py", line 358, init    db.read_windows_registry()  File "J:\Program Files (x86)\Python\Python27\lib\mimetypes.py", line 258, iead_windows_registry    for subkeyname in enum_types(hkcr):  File "J:\Program Files (x86)\Python\Python27\lib\mimetypes.py", line 249, inum_types    ctype = ctype.encode(default_encoding) # omit in 3.x!UnicodeDecodeError: 'ascii' codec can't decode byte 0xb0 in position 1: ordinnot in range(128)Storing debug log for failure in C:\Users\Administrator\pip\pip.log

Solution: Open the mimetypes. py file under C: \ Python27 \ Lib and find

default_encoding = sys.getdefaultencoding()

Changed:

if sys.getdefaultencoding() != 'gbk':    reload(sys)    sys.setdefaultencoding('gbk')default_encoding = sys.getdefaultencoding()

After the installation is successful, verify whether the installation is successful:

C:\Users\Administrator>pythonPython 2.7.6 (default, Nov 10 2013, 19:24:24) [MSC v.1500 64 bit (AMD64)] on 32Type "help", "copyright", "credits" or "license" for more information.>>> from bs4 import BeautifulSoup>>> exit()

If no error is reported for "from bs4 import BeautifulSoup", the installation is successful. Otherwise, a similar error is reported as follows:

Traceback (most recent call last):  File "<stdin>", line 1, in <module>ImportError: No module named bs4
