Node js runing error

nodejs

#1

I run node js using “node app.js”, then I just close the terminal. I think the application has stopped. But there is some error when I ran node again. Anyone have idea with it?

Error: libclntsh.so.12.1: cannot open shared object file: No such file or directory
at Error (native)
at Object.Module._extensions…node (module.js:434:18)

Then I need to set the link path agin
export LD_LIBRARY_PATH=/opt/oracle/instantclient:$LD_LIBRARY_PATH
