react native 0.57 cannot resolve module "@babel/plugin-external-helpers" #21214
Comments
ios也一样的问题 |
Workaround: npm install --save-dev @babel/plugin-external-helpers |
Fixed |
Seems related to this facebook/metro#198 |
|
@sopranolinist After installing it, what's the error shown? |
@HsuWai same error as before adding the babel plugin package: |
Ok.. If so, I think you should take a look and try like what @sunnylqm said. |
Remember to restart packager after installing any package. My link above does not provide any direct fix, just for reference. |
@sunnylqm So, is there a way to solve this problem? |
@hqwlkj |
In addition to above suggestion, I rebooted and deleted old build folder
and it worked - thanks

@git-Asir Are you upgrading to 0.57? Make sure you have followed the steps here https://github.com/react-native-community/react-native-releases/blob/master/CHANGELOG.md#updating-to-this-version |
The same to you |

This is happening to me too and installing @babel/plugin-external-helpers doesn't help. I'm on a Mac. This happened with my main project, and then I created a new test project from scratch and it happened with that as well. |
@git-Asir my @babel/plugin-external-helpers version is also 7.0.0. |
We are working on a fix with Metro team. Here's explanation from the issue I've opened today: #21219 (comment) |
Fixed in facebook/metro@48fa696 |
For me it was coming because of mismatch in the versions of the dependencies. "dependencies": { |
