[Summary]  
I had some trouble with Revise.jl before as mentioned [here](https://discourse.julialang.org/t/revise-jl-randomly-fails-to-notice-rsynced-code-changes/23589).  
`rsync` with option `-I` seems fix the bug. ~~At this time, I’m literally newbie of Julia so I may not figure out what I did.~~

 

~~However, `rsync -I` occurs this issue (Revise.jl cannot trace files).  
Anyway, Revise.jl now works well without `rsync -I`.  
 ~~  
As @ericphanson [said](https://discourse.julialang.org/t/should-i-turn-on-off-repeatedly-to-reflect-changes-of-currently-developing-packages/47560/18), `JULIA_REVISE_POLL=1` will reflect changes for every few seconds.  
If you use write codes in local pc and run the codes in server, `rsync` with option `-I` immediately reflects changes even without polling of Revise.jl.

EDIT: Nah, I found out what have made this error. That was **the precompile with PackageCompiler.jl**. ~~The rsync option does not matter.~~ Probably [this](https://discourse.julialang.org/t/revise-jl-and-packagecompiler-jl-are-not-compatible/47567/3) will explain you.

So I decided to use Revise.jl with `rsync -I` while developing packages.
