回答1:

Use this :

step 1: add these two lines in gradlew.properties Visit for complete guideline

android.useAndroidX=true
android.enableJetifier=true

step 2: use these commands

First of all remove node_modules folder and reinstall it using

npm install

yarn

and then

npm install --save-dev jetifier 
npx jetify  
npx react-native run-android

Call

npx jetify

every time when (your dependencies update or every time you install node_modules you have to jetify again)

回答2:

Use this:

react-native run-android --no-jetifier

回答3:

Just change from "C" directory to any other directory and then install/run starting from here "npm install -g react-native-cli" . Then create new project "react-native init AwesomeProject " use Yarn to install dependencies fast. It worked for me.

回答4:

The issue is in React Native CLI v2.6.1

Use Below steps to resolve the issue:

If you use lock files (yarn.lock or package-lock.json) - find the @react-native-community/cli entry, remove it, run yarn install / npm install once again.
If you don't use lock files – remove node_modules and run yarn install / npm install again.
Run yarn list @react-native-community/cli or npm list @react-native-community/cli and verify you're on the latest version (v2.6.2).
Run react-native run-android

回答5:

react-native run-android --no-jetifier

and again start server

react-native start

回答6:

I use this react-native run-android --no-jetifier worked me
