无法使用easy_install安装pip

Question

我正在尝试安装pip ：

$ sudo easy_install pip

得到此错误：

Searching for pip
Reading https://pypi.python.org/simple/pip/
Couldn't find index page for 'pip' (maybe misspelled?)
Scanning index of all packages (this may take a while)
Reading https://pypi.python.org/simple/
No local packages or download links found for pip
error: Could not find suitable distribution for Requirement.parse('pip')

我已经检查过安装了python：

$ python --version
Python 2.7.10

根据多线程，这应该正常工作，我做错了什么？

下载https://bootstrap.pypa.io/get-pip.py并运行：

python get-pip.py

我收到这个错误：

Answer 1

为什么不遵循官方文件？

要安装pip，请安全下载get-pip.py。 2

然后运行以下命令：

$ python get-pip.py

来自pip官方文件

以及get-pip.py的实际链接

如果你想在你的机器python2.7或python3.x而不是python上安装特定的python版本。
