Hello @Yoon_Kiseok, welcome to the community!
It seems konlpy does need a Java install to properly run. To install Java on a Streamlit Sharing app, you should add a ´packages.txt’ file at the root with ´default-jre’ inside, and reboot your app to run the install.
See Run librairies relying on Java to work? (e.g. PySpark) - #5 by randyzwitch for an example.
Hope this solves the problem!
