我们从Python开源项目中，提取了以下50个代码示例，用于说明如何使用pip.commands.commands()。
def run(self, options, args): from pip.commands import commands, get_similar_commands try: # 'pip help' with no args is handled by pip.__init__.parseopt() cmd_name = args[0] # the command we need help for except IndexError: return SUCCESS if cmd_name not in commands: guess = get_similar_commands(cmd_name) msg = ['unknown command "%s"' % cmd_name] if guess: msg.append('maybe you meant "%s"' % guess) raise CommandError(' - '.join(msg)) command = commands[cmd_name]() command.parser.print_help() return SUCCESS
