error while loading shared libraries: so: cannot open shared object file: No such file or directory

利用LD_DEBUG=libs解决找不到文件的问题，通常情况都是在系统路径下没有对应的文件，那么这个命令就能够发现缺少的文件，并且能看到查找的路径

[root@localhost tmux-2.6]# tmux -V

tmux: error while loading shared libraries: libevent-2.1.so.6: cannot open shared object file: No such file or directory

[root@localhost tmux-2.6]# LD_DEBUG=libs tmux -V | grep libevent

     54283:      search cache=/etc/ld.so.cache

tmux: error while loading shared libraries: libevent-2.1.so.6: cannot open shared object file: No such file or directory

找到缺少的文件位置

[root@localhost tmux-2.6]# ll /usr/local/tmux/lib/libevent-2.1.so.6

lrwxrwxrwx. 1 root root 21 Mar 16 00:05 /usr/local/tmux/lib/libevent-2.1.so.6 -> libevent-2.1.so.6.0.2

做个软连接到系统路径下

[root@localhost tmux-2.6]# ln -s /usr/local/tmux/lib/libevent-2.1.so.6 /usr/lib64/libevent-2.1.so.6

这样就能找到缺少的文件了：

[root@localhost tmux-2.6]# tmux -V
tmux 2.6
