Question

I'm practicing REACT NATIVE on UBUNTU 18.x OS, everything was running smooth, yesterday i updated my React native,react & android gradle versions then i recived some error like server adb & client adb doesn't match, i fixed this issue using some commands now once the new project run fine, but as soon as i rebooted my system & run the project,it thrown the error

then i checked adb

+adb

output:bash: /usr/bin/adb: No such file or directory

+which adb

output:/usr/bin/adb

+type adb

output:adb is hashed (/usr/bin/adb)

+adb devices

output:bash: /usr/bin/adb: No such file or directory

please help me to resolve this error!

Answer 1

To my knowledge it can be resolved by increasing the num of max users in sysctl.conf on UBUNTU you can run

sudo nano /etc/sysctl.conf

then press ctrl+O then press ENTRE then take the cursor on the end of file and place this line there

fs.inotify.max_user_watches=100000

or simply run this command

sudo sysctl -w fs.inotify.max_user_watches=100000
