Question

用get-pip.py

安装pip后

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

当我尝试使用pip -V

检查安装时出现此错误

Traceback (most recent call last):
File "/usr/bin/pip", line 5, in <module>

raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'pip==6.1.1' distribution was not found and is required by the application

然而，这适用于python2.6。

为什么会发生这种情况我有什么理由失踪？

我正在使用Amazon Linux AMI发布2016.03，我猜这是基于一些RedHat发行版

Answer 1

尝试安装virtualenv以独立管理您的版本：

sudo apt-get install virtualenv

创建虚拟环境

virtualenv newvenv

运行新环境

source newvenv/bin/activate

最后

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

Answer 2

可能你有一个Ubuntu图像。在安装新版本之前，您需要删除系统点版本。

在命令之前执行apt-get remove python-pip，你将安装一个合适的pip。

对于python3：apt-get remove python3-pip

同样适用于基于CentOS的那些但你必须用yum代替apt-get

pip：在ec2 AMI上使用python2.7安装错误
