While this previous answermight be the reason, this snipped worked for me as a solution (in Ubuntu 14.04):

虽然这个先前的答案可能是原因，但这个剪辑对我来说是一个解决方案（在Ubuntu 14.04）：

First remove the package from the package manager:

首先从包管理器中删除包：

# apt-get remove python-pip

And then install the latest version by side:

然后并排安装最新版本：

# easy_install pip

The problem is the Python module requests. It can be fixed by

问题是 Python 模块requests。它可以通过

$ sudo apt-get purge python-requests
[now requests and pip gets deinstalled]
$ sudo apt-get install python-requests python-pip

If you have this problem with Python 3, you have to write python3instead of python.

如果您在 Python 3 中遇到此问题，则必须编写python3而不是python.

回答by Aufziehvogel

This problem is caused by a mismatch between your pip installation and your requests installation.

此问题是由 pip 安装和 requests 安装之间的不匹配引起的。

As of requests version 2.4.0 requests.compat.IncompleteReadhas been removed. Older versions of pip, e.g. from July 2014, still relied on IncompleteRead. In the current versionof pip, the import of IncompleteReadhas been removed.

截至请求版本 2.4.0requests.compat.IncompleteRead已被删除。旧版本的 pip，例如从 2014 年 7 月开始，仍然依赖于IncompleteRead. 在当前版本的 pip 中，IncompleteRead已删除的导入。

So the one to blame is either:

因此，应该归咎于：

• requests, for removing public API too quickly
• Ubuntu for updating pip too slowly

• 请求，用于过快删除公共 API
• Ubuntu 更新 pip 太慢

You can solve this issue, by either updating pip via Ubuntu (if there is a newer version) or by installing pip aside from Ubuntu.

您可以通过通过 Ubuntu 更新 pip（如果有更新版本）或安装 pip 来解决这个问题，除了 Ubuntu。

On Ubuntu 14.04 I resolved this by using the pip installation bootstrap script, as described in the documentation

在 Ubuntu 14.04 上，我通过使用 pip 安装引导脚本解决了这个问题，如文档中所述

wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

That's an OK solution for a development environment.

对于开发环境来说，这是一个不错的解决方案。

For fixing pip3 (worked on Ubuntu 14.10):

用于修复 pip3（适用于 Ubuntu 14.10）：

easy_install3 -U pip

回答by ggll

Check wether you have an older version of requestssitting in your ~/.local/lib/python2.7/site-packages/and remove it if it is the case (change path to reflect your python version). This solved the issue for me.

请检查是否你有一个旧版本的requests坐在你~/.local/lib/python2.7/site-packages/并删除它，如果它是（以反映您的Python版本的变化路径）的情况下。这为我解决了这个问题。

我尝试了所有答案，但无法做到。

Did this and worked

After that I just installed virtualenv with pip

I built the virtualenv that I was working on and the package was installed easily. Get into the virtualenv by using source /bin/activateand try to install your package, for example:
