安装了python2.7，第一次执行时报错：errorwhileloadingsharedlibraries:libpython2.7.so.1.0:cannotopensharedobjectfile:Nosuchfileordirectory 解决方法如下：
1.编辑vi/etc/ld.so.conf如果是非root权限帐号登录，使用sudovi/etc/ld.so.conf添加上python2.7的lib库地址，如我的/usr/local/Python2.7/lib，保存文件
2.执行/sbin/ldconfig-v命令，如果是非root权限帐号登录，使用sudo/sbin/ldconfig-v。
这样ldd才能找到这个库，执行python2.7就不会报错了 /etc/ld.so.conf:这个文件记录了编译时使用的动态链接库的路径。
默认情况下，编译器只会使用/lib和/usr/lib这两个目录下的库文件如果你安装了某些库，没有指定--prefix=/usr这样lib库就装到了/usr/local下，而又没有在/etc/ld.so.conf中添加/usr/local/lib，就会报错了 ldconfig是个什么东东吧：它是一个程序，通常它位于/sbin下，是root用户使用的东东。
具体作用及用法可以manldconfig查到简单的说，它的作用就是将/etc/ld.so.conf列出的路径下的库文件缓存到/etc/ld.so.cache以供使用 因此当安装完一些库文件，(例如刚安装好glib)，或者修改ld.so.conf增加新的库路径后，需要运行一下/sbin/ldconfig使所有的库文件都被缓存到ld.so.cache中，如果没做，即使库文件明明就在/usr/lib下的，也是不会被使用的，结果编译过程中抱错，缺少xxx库。

安装了python2.7，第一次执行时报错：errorwhileloadingsharedlibraries:libpython2.7.so.1.0:cannotopensharedobjectfile:Nosuchfileordirectory 解决方法如下：
1.编辑vi/etc/ld.so.conf如果是非root权限帐号登录，使用sudovi/etc/ld.so.conf添加上python2.7的lib库地址，如我的/usr/local/Python2.7/lib，保存文件
2.执行/sbin/ldconfig-v命令，如果是非root权限帐号登录，使用sudo/sbin/ldconfig-v。
这样ldd才能找到这个库，执行python2.7就不会报错了 /etc/ld.so.conf:这个文件记录了编译时使用的动态链接库的路径。
默认情况下，编译器只会使用/lib和/usr/lib这两个目录下的库文件如果你安装了某些库，没有指定--prefix=/usr这样lib库就装到了/usr/local下，而又没有在/etc/ld.so.conf中添加/usr/local/lib，就会报错了 ldconfig是个什么东东吧：它是一个程序，通常它位于/sbin下，是root用户使用的东东。
具体作用及用法可以manldconfig查到简单的说，它的作用就是将/etc/ld.so.conf列出的路径下的库文件缓存到/etc/ld.so.cache以供使用 因此当安装完一些库文件，(例如刚安装好glib)，或者修改ld.so.conf增加新的库路径后，需要运行一下/sbin/ldconfig使所有的库文件都被缓存到ld.so.cache中，如果没做，即使库文件明明就在/usr/lib下的，也是不会被使用的，结果编译过程中抱错，缺少xxx库。
