npm install -g expo-cli fails with "EPERM: operation not permitted, unlink '...\adb.exe'

Question

I receive an error when running

$ npm install -g expo-cli

I have tried reinstalling the node modules as An Administrator but the same error occurs.

Environment: Windows 10, Node Version: 10.15.3, NPM Version: 6.9.0

I expect the install to happen but an error like this occurs:

Answer 1

Go through this line from your error log, it says 'C:\Users\Griseld\AppData\Roaming\npm\node_modules\expo-cli\node_modules.xdl.DELETE\binaries\windows\adb\adb.exe' npm ERR!

the expo cli wasn't installing simply because your adb is still using the previously installed expo cli on your system. had similar issue not quite long...kill the process adb.exe

Answer 2

The steps I followed (May this follow help you.)

1. npm uninstall -g expo-cli (If already have installed any version on your machine)
2. npm clear cache --force
3. Killed Abd.exe from Task Manager
4. npm uninstall -g expo-cli

It worked for me, good luck.

Answer 3

Go to your task manager and kill the process of Adb.exe and boom.
