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

我收到以下错误

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

当我尝试安装python-setuptools时, sudo apt-get install python-setuptools我得到以下错误

解释我如何解决错误并指导我python-pip安装的步骤.

Answer 1

我安装python-pip时得到了同样的错误,以下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 2

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权限):

python get-pip.py

这应该让你去.如果再次卡住,请在此处阅读:http://pip.readthedocs.org/en/stable/installing/
