ubuntu 软件安装问题

babydavic

出现以下错误的时候，error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory  代表某些包，软件是没有办法引用依赖包

    因此 ： 我们可以通过以下方法进行查找缺少的包的查找路径

     LD_DEBUG=libs /usr/local/bin/fdfs_test -v 2>&1 > /dev/null | less

    因为我们看见 查找顺序如下：

     17166:     find library=libevent-1.4.so.2 [0]; searching

/usr/local/bin/fdfs_test: error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory

最后我们通过 将已经安装好的软件包进行软连接 ，就可以将问题解决

ln -s /usr/local/lib/libevent-1.4.so.2 /lib/libevent-1.4.so.2
