React Native STUCK starting packager

I had the same issue. I solved it by changing react-native-scripts version from "^1.14.1" to "1.14.0" and run npm install again.

after a long search I found a solution for this problem:

this problem is caused by another watchman process, to solve it you have to turn off the watchman process

first,check react,react-native,and expo version are they compatible, goto here

Then you must install watchman, goto https://facebook.github.io/watchman/docs/install.html. Check watchman has installed by:

watchman -v

result:

4.9.4

After that, type in terminal or cmd:

watchman watch-del-all

result:

{
"version": "4.9.4",
"roots": [
    "C:/Users/***/Documents/Project/quickCountAndroidCrna"
]

}

look in the "roots" section:

"roots": [
    "C:/Users/***/Documents/Project/quickCountAndroidCrna"
]

if "roots" not empty, you must shutdown watchman process, typing this in terminal or cmd:

watchman shutdown-server

result:

{
"version": "4.9.4",
"shutdown-server": true

}

run again watchman watch-del-all you will get result with empty roots like this:

{
"version": "4.9.4",
"roots": []

}

after that you can run npm start or yarn start or other command to start your react-native project.

if the problem still occurs, repeat the above method several times, make sure the "roots" are empty! in my case, even I had to repeat it up to 3 times.
