python - 无法使用 easy_install 安装 pip

Question

我正在尝试安装pip:

$ sudo easy_install pip

收到此错误:

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')

我已经检查了 python 是否已安装:

$ python --version
Python 2.7.10

根据多个线程，这应该可以正常工作，我做错了什么？

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

python get-pip.py

我收到此错误:

Answer 1

为什么不遵循官方文档？

To install pip, securely download get-pip.py. 2

Then run the following:

$ python get-pip.py

来自official doc of pip

以及指向 get-pip.py 的实际链接

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