react-native run-android --no-jetifier work.
But I want to know if it will have any effect?

React Native version:
version 0.60. ++

This is also happening to me, I updated everything today, even uninstalled and reinstalled to the latest versions of node and android, and I've already created to react-native apps.
Just doing react-native init project, then going to the directory of my project and executing react-native run-android and that's all it takes for that message to pop-up.
I understand Google just did a major update or at least a relevant update with AndroidX, and I'm sure we all will need to be sure our apps can run with this new update.
Doing the --no-jetifier thing is just a temporary thing and can’t keep doing it forever.
On that same note, executing in the terminal yarn add jetify doesn’t do much.

you are right
error An unexpected
error occurred: "https://registry.yarnpkg.com/jetify: Not found".

[janibhargav]

i think this is a bug, please open a bug report

[zhudan1027]

I had the same problem.It worked yesterday.
Another post said use this command to start.
react-native run-android --no-jetifier

[janibhargav]

temporary run with
react-native run-android --no-jetifier

[yang200258]

确实出错了，是因为react-native的更新问题吗？

[tafea345]

still having the same issues
Another post said use this command to start.
react-native run-android --no-jetifier
this works fine but you can't keep running like this all the time
i hope there will be a fix soon

[jin006s]

same issues , please fix soon

[niedem]

--no-jetifier doesnt work either if you have a lib that requires jetifier such as react-native-gesture-handler

[ShantkumarMethre]

cmd react-native run-android --no-jetifier
it will work

[narratones]

I've just built from the latest and received no errors, as below:

react-native init NewProject

npx react-native run-android

This didn't start my metro builder, so in another terminal -

react-native start

Then:

npx react-native run-android

Environment:

Node : v10.2.1
NPM/NPX: v6.9.0
