AttributeError：'module'对象没有属性'python_implementation'运行pip [英] AttributeError: 'module' object has no attribute 'python_implementation' running pip

问题描述

我使用Python安装工具安装了Cygwin。当我尝试运行pip install awscli 时，得到以下错误：

I installed Cygwin with Python set-up tools. When I try to run pip install awscli I get the following error:

$ pip install awscli
Traceback (most recent call last):

AttributeError: 'module' object has no attribute 'python_implementation'

我在路径中缺少一些东西，或者是我的Python实现hosed？

Am I missing something in my path or is my Python implementation hosed?

推荐答案

重新安装 pip 可能会修复它，请使用 easy_install ：

Re-installing pip might fix it, try it using easy_install:

sudo easy_install pip
