python-2.7 - Python 和请求 |导入错误 : No module named util

Question

我刚刚在新计算机上安装了包请求。当我尝试导入该模块时出现此错误。任何想法是什么导致了 util 模块的问题？

Python 2.7.6 (v2.7.6:3a1db0d2747e, Nov 10 2013, 00:42:54) 

[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin

我在 pypi.python.org 上看到了 requests 的最新版本是 2.2.1

您的 list 显示，您已经安装了 2.3.0 版本，因此很可能您正在使用尚未真正完成的开发版本。

卸载它:

$ pip uninstall requests

并安装生产质量一:

$ pip install requests

如果它仍然会与 2.3.0 版本混淆，请显式安装 2.2.1

$ pip install requests==2.2.1
