In Ubuntu, pipis provided by the python-pippackage. You can install it in the Software Center, or, if you prefer to use the command line:
在 Ubuntu 中，pip是由python-pip包提供的。您可以在软件中心安装它，或者，如果您更喜欢使用命令行：
sudo apt-get update && sudo apt-get install python-pip
If you have not already installed python-devand build-essential, you should install them too. (But it seems your apt-getcommand mighthave successfully installed them. If you're not sure, you can check by trying to install them again. Or with apt-cache policy python-dev build-essential.)
如果您还没有安装python-devand build-essential，您也应该安装它们。（但似乎您的apt-get命令可能已成功安装它们。如果您不确定，您可以通过尝试再次安装它们来进行检查。或者使用apt-cache policy python-dev build-essential.）
Once the necessary software is installed, if you wish to update it further, you can do so with pipitself, by running:
安装必要的软件后，如果您希望进一步更新它，您可以pip通过运行以下命令对其进行更新：
sudo pip install --upgrade pip
sudo pip install --upgrade virtualenv
