在编辑Django应用程序期间，我删除了＆＃34; usr / lib / python2.7＆＃34;中的python2.7文件夹。错误的。
发生这个问题后，我总是在使用时得到msg如下：
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
--- os是Ubuntu12.04 ----
我试图参考这些页面：
并尝试使用
sudo apt-get install --reinstall重新安装python2.7.8版本
我的PYTHONPATH现在看起来像
PYTHONDIR = usr / local / lib / python2.7，
PYTHONHOME = usr / local / lib / python2.7，
PYTHONPATH =
但我仍然得到＆＃34; ImportError：没有名为site＆＃34的模块; MSG
如果我尝试输入
Import sys
我会得到msg＆＃34; import：无法打开图像`sys＆＃39;：@ error / blob.c / OpenBlob / 2587。＆＃34;
非常感谢，

首先，要小心 - 甚至是限制性的 - 关于你以root身份运行的东西。普通用户无法修改/ usr / lib下的内容，并且有充分的理由 - 它会破坏系统。
其次，您可以使用以下命令找出该目录中包含的内容：
$ dpkg -S /usr/lib/python2.7

（是的，列表很长。）知道该列表，我们可以请求重新安装这些包：
$ sudo apt-get install --reinstall `dpkg -S /usr/lib/python2.7 | sed -e s/,//g -e 's/: .*$//'`
我为很长的命令行道歉;这里的sed命令清除dpkg的输出，只生成我们要重新安装的包列表。这种方法很可能有助于你提到的具体问题，但即使它出现一次也表明你不清楚其他变化的结果。您可能希望放慢速度并了解有关系统结构的更多信息。
像PYTHON*变量之类的东西对你没有多大帮助，除非你在其他地方有一个精确匹配的Python版本，我们在Linux发行版上往往会避免这种情况，因为我们通常有工作（尽管有限）的包管理。
最后，我认为这个问题最终会超出堆栈溢出的超级用户问题。
