我有一个文件,意味着一个实用程序文件.该文件应包含许多静态方法.

我应该这样定义类中的方法:

#utility.py
class utility(object):
    @staticmethod
    def method1(a,b,c):
        pass

    @staticmethod
    def method2(a,b,c):
        pass

或者像这样使用它(没有课程):

#utility.py
def method1(a,b,c):
    pass

def method2(a,b,c):
    pass

我已按照https://github.com/Valloric/YouCompleteMe中的说明进行操作, 并已安装:

cmake的 sudo apt-get install build-essential cmake

和Python标题 sudo apt-get install python-dev python3-dev

然后我cd ~/.vim/bundle/YouCompleteMe跑了: ./install.py --clang-completer我得到了:

Searching Python 2.7 libraries... ERROR: unable to find an appropriate Python library.

然后我试过 python3 install.py --clang-completer 但仍然得到:

Searching Python 3.4 libraries... ERROR: unable to find an appropriate Python library.

有没有人知道发生了什么？谢谢

我想用生菜写一些简单的单元测试.
(更具体地说,我正在遵循本教程:https://semaphoreci.com/community/tutorials/bdd-testing-a-restful-web-application-in-python)
我刚安装了生菜:

$ pip3 install lettuce

当我跑

$ lettuce test/features 

我明白了:

Traceback (most recent call last):
