我正在尝试升级matplotlib。Ubuntu 12.04当我运行命令时：
sudo pip install --upgrade matplotlib
我收到此错误：
Downloading/unpacking matplotlib
Running setup.py egg_info for package matplotlib
The required version of distribute (>=0.6.28) is not available,
and can't be installed while this script is running. Please
install a more recent version first, using
'easy_install -U distribute'.
(Currently using distribute 0.6.24dev-r0 (/usr/lib/python2.7/dist-packages))
Complete output from command python setup.py egg_info:

----------------------------------------
Command python setup.py egg_info failed with error code 2
Storing complete log in /home/gabriel/.pip/pip.log
所以我跑：
easy_install -U distribute
我得到：
Traceback (most recent call last):
File "/home/gabriel/Enthought/Canopy_32bit/User/bin/easy_install", line 9, in <module>
load_entry_point('distribute', 'console_scripts', 'easy_install')()
File "/home/gabriel/Enthought/Canopy_32bit/User/lib/python2.7/site-packages/setuptools-0.9.8-py2.7.egg/pkg_resources.py", line 378, in load_entry_point
return get_distribution(dist).load_entry_point(group, name)

raise ImportError("Entry point %r not found" % ((group,name),))
ImportError: Entry point ('console_scripts', 'easy_install') not found
所以有些东西不适用于我的Canopy安装。我现在正在使用Spyder，所以我可以卸载Canopy以查看是否有帮助，但命令sudo apt-get remove enthought*并sudo apt-get remove canopy*没有找到要删除的内容。
我可以做些什么来升级 matplotlib？
添加
我按照说明Canopy从这里删除，现在当我运行时，easy_install -U distribute我得到：
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
ImportError: No module named site
我认为这与我source ~/Enthought/Canopy_64bit/User/bin/activate从~/.profile. 我尝试以 sudo 运行以下命令：
apt-get autoclean
apt-get clean
apt-get update
apt-get upgrade
apt-get dist-upgrade
apt-get -f install
dpkg --configure -a
apt-get install --reinstall python
但这没有用。有想法该怎么解决这个吗？
添加 2
我尝试PYTHONHOME使用以下命令进行设置：
export PYTHONHOME=/usr/lib/python2.7
现在easy_install -U distribute返回：
ImportError: No module named site
同样的事情：
export PYTHONHOME=/usr/local/lib/python2.7
所以现在开始追逐那个错误。
添加 3
环境：
export PYTHONHOME=/usr/lib/python2.7/
然后将命令运行为sudo：
sudo easy_install -U distribute
成功了。然后我就可以跑了sudo pip install --upgrade matplotlib。我会在一分钟内将其添加为答案。
