如何测试我是否已成功安装Python模块？

Question

I tried to install beautifulsoup. I get such an error:
<-- snip -->

raise MissingSectionHeaderError(fpname, lineno, line)
ConfigParser.MissingSectionHeaderError: File contains no section headers.
file: /Users/Sam/.pydistutils.cfg, line: 1
'install_lib = ~/Library/Python/$py_version_short/site-packages\n'

I get an similar error as I run my Python code in vim by: :!python %

Answer 1

You can test if a module is installed like so:

$ python
>>> import modulename

Answer 2

I'd try the following:

1. Open Python shell
2. Type import <moduleName>
3. Parse the results (no error, ImportError or some module loading error)
4. Try to invoke any function from imported module (to see if module is correctly initialized).

Do you need something more sophisticated?

try: from prettytable import PrettyTable except: try: print "\\033[31mPython-prettytable Module [Not Available]\\033[0m" os.system('sudo apt-get install python-setuptools') os.system('sudo easy_install prettyTable') print "\\033[33mPython-prettytable Module [Installed]\\033[0m" except: print "PrettyTable Python Module Installation failed." print "\\033[32mPython-prettytable Module [Available]\\033[0m"
