pip install错误:无法导入名称'unpack_url'

Question

我在Windows 8.1机器上使用64位64位Python.皮普最近给了我一些问题,特别是这个错误:

C:\Users\Charlie\Desktop>pip install wxPython_Phoenix-3.0.3.dev78341-cp34-none-w
in_amd64.whl
Traceback (most recent call last):

    from pip.download import (url_to_path, unpack_url)
ImportError: cannot import name 'unpack_url'

每次我尝试安装任何软件包时都会发生这种情况.以前有人有这个问题吗？

Answer 1

我用过:easy_install -U pip 问题解决了

Answer 2

嗯,很明显有一个错误pip,并unpack_url可能是使用一封来自PyPI下载软件包.我建议通过执行此脚本重新安装.
