Question

我想通过matplotlib安装pip。但是，我遇到了循环问题，在某些时候我陷入困境。在终端中运行pip会产生：

Traceback (most recent call last):
  File "/usr/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
  File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 3080, in <module>
  File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 3066, in _call_aside

  File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 839, in resolve
pkg_resources.DistributionNotFound: The 'pip==1.5.4' distribution was not found and is required by the application

我尝试使用easy_install解决此问题，但它产生了以下错误消息：

Traceback (most recent call last):
  File "/usr/bin/easy_install", line 5, in <module>
    from pkg_resources import load_entry_point
  File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 3080, in <module>

pkg_resources.DistributionNotFound: The 'setuptools==3.3' distribution was not found and is required by the application

正在运行sudo apt-get install python-setuptools说我已经拥有最新版本。

我的操作系统是Ubuntu 14.04。我已经尝试了许多不同的方法来解决这个问题，并可能最终造成进一步的伤害。我不记得我做过的一切以及我在这个阶段的结局，所以很遗憾无法提供进一步的信息。

我的目标是最终安装matplotlib并保持所有python相关库的稳定状态。任何解决方案都可行，所以我不介意重新安装一切或任何能解决问题的方法。

但是，matplotlib仍未找到python。

Answer 1

尝试：

sudo apt-get build-dep python-matplotlib

这应该通过Ubuntu软件包管理系统安装matplotlib需要的依赖项（因为很多这些依赖项与pip一起安装并不容易），使您能够：

 pip install matplotlib

来源：Matplotlib documentation

我在Ubuntu 14.04和Kubuntu 15.10上都使用了这个过程来安装最新的，稳定的matplotlib（在虚拟环境中，但这应该没什么区别）。

如何解决依赖地狱以安装matplotlib？
