gradle - spawnSync ./gradlew EACCES error when running react native project on emulator udara

Question

I am trying to use react-native run-android to install my react-native application on an android studio emulator. I have checked with abd-devices that the emulator is available, and I have ran npm-install.

I am using Ubuntu 18.04 with the latest version of android studio, and the latest Pixel 2 XL API 28.

I get the following error:

spawnSync ./gradlew EACCES

Error: spawnSync ./gradlew EACCES

    at processTicksAndRejections (internal/process/next_tick.js:81:5)

I have tried restarting my PC and the emulator several times. Any ideas?

UPDATE: I reinstalled JDK, npm, react-native-cli and android studio. It still gives me the exact same error. Please help.

I fixed this problem with:

chmod 755 android/gradlew 

the chmod command sets the permissions of files or directories. https://www.computerhope.com/unix/uchmod.htm
