Unable to run npm start in create-react-app - node.js

Question

PROBLEM
Need to run my react project
I have install create-react-app and create a project, When I tried to run project using npm start its showing some error
When I first tried in my home dir everythings work fine, Problem only when I tried to create and run in specfic dir
USING
Kubuntu OS,
Nodejs : V10.15.3
npm : 6.9.0
By little bit of google I done following thing
Remove nodemodule and install
Clear npm cache and one again try it as fresh
Uninstall and install both node and npm
Access the project as root
When I try to : npm ls react
kasi#kasi:~/my/node_modules$ npm ls react
my#0.1.0 /home/kasi/my
`-- react#16.8.6
No other things
Some Google - Check point:
kasi#kasi:~/my/node_modules$ which node
/home/kasi/.nvm/versions/node/v10.15.3/bin/node
kasi#kasi:~/my/node_modules$ which npm
/usr/bin/npm
kasi#kasi:~/my/node_modules$ cd ../../../../usr/local/bin/
kasi#kasi:/usr/local/bin$ ls
create-react-app n node npx tsc tsserver
TIP:
All my disk are FAT type so some problem may be on symlink
When I try to start direct as follow
kasi#kasi:/media/kasi/others/reaact/myapp$ node node_modules/react-scripts/scripts/start.js
It show
Starting the development server...
