无法在Ubuntu 14.04上安装python pip

Question

这是我用来安装python pip的命令

sudo apt-get install python-pip

我得到以下错误

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have

              Recommends: python-dev-all (>= 2.6) but it is not installable
E: Unable to correct problems, you have held broken packages.

我已经安装了最新版本的python dev

当我尝试使用 sudo apt-get install python-setuptools我得到以下错误

Reading package lists... Done

解释如何解决错误并指导我安装python-pip的步骤。

Answer 1

除了@似乎推荐的解决方案之外，我还必须运行这个。

apt-get update

（或）

sudo apt-get install python-setuptools python-dev build-essential 
sudo easy_install pip 

Answer 2

当我安装python pip时出现同样的错误，下面的命令解决了我的问题。

sudo apt-get install python-pkg-resources=3.3-1ubuntu1
sudo apt-get install python-setuptools

Answer 3

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

然后运行以下命令（可能需要管理员访问）：

python get-pip.py

这会让你走的。 如果你又卡住了，读这里：http://pip.readthedocs.org/en/stable/installing/
