Python / IPython ImportError：没有名为site的模块
我有 python 2.7.3 和 ipython 1.2 在我的上正确运行Linux 系统（ ubuntu 12.04 ）但是正在尝试安装课程作业所需的matplotlab的更新版本。
I had python 2.7.3 and ipython 1.2 up and running correctly on my Linux system (ubuntu 12.04) but was trying to install an updated version of matplotlab needed for coursework.
在终端中运行此代码行后
After running this code line in the terminal
user$ sudo easy_install -U distribute
user$ export PYTHONHOME=/usr/lib/python2.7/
现在我每次尝试运行 python 或 ipython 我收到错误消息
now every time I try and run python or ipython I get the error message
ImportError: no module named site
如何撤消/解决此问题？ ？我迷路了。我看了其他类似的问题，但没有人使用 Linux ，我不知道该怎么做。
how do I reverse/fix this problem?? I'm so lost. I looked at other similar issues, but no one else used Linux and I'm not sure what to do.
更改标准Python的位置库。默认情况下，
库在前缀/ lib / pythonversion和
exec_prefix / lib / pythonversion中搜索，其中prefix和exec_prefix是
依赖于安装的目录，两者都默认为/ usr / local。
Change the location of the standard Python libraries. By default, the libraries are searched in prefix/lib/pythonversion and exec_prefix/lib/pythonversion, where prefix and exec_prefix are installation-dependent directories, both defaulting to /usr/local.
当PYTHONHOME设置为单个目录时，其值将替换
前缀和exec_prefix。要为这些指定不同的值，请将
PYTHONHOME设置为前缀：exec_prefix。
When PYTHONHOME is set to a single directory, its value replaces both prefix and exec_prefix. To specify different values for these, set PYTHONHOME to prefix:exec_prefix.
尝试清理 PYTHONHOME ：
user$ export PYTHONHOME=
至于安装matplotlib，我建议如下：
As for installing matplotlib, I would recommend the following:
sudo apt-get install python-matplotlib
