Question

我在新系统上安装了64位Ubuntu 12.04，无法安装functools。我已多次安装，但不记得收到此错误，并且无法通过Google找到任何解决方案。我需要做什么？

Answer 1

Python2.7随附functools模块。

如果你想获得Python3.2引入的lru-cache装饰器，你可以安装functools32。

编辑：我实际检查过这个。当我尝试使用Python2.7 pip-install functools时，我遇到了同样的错误。只需做import functools并照常进行。

Answer 2

在Windows上找到解决方案。

删除site-packages文件夹中对functools的任何引用。
easy_install -U pip==7.1.2

Answer 3

确保在python 2.x版本中它是functools32。在3.x中，这些工具是内置的。

安装functools给了我AttributeError'module'对象没有属性'compose'
