Every time I try to create a new React Native app, I receive this error in the Metro Bundler:

error Unexpected token =.
/Users/lukeschoenberger/repos/PodApp/node_modules/metro-cache/src/stores/HttpStore.js:31
  static HttpError = HttpError;
                   ^

I'm running: npx react-native run-ios.

When I create the script, I create the app, I run: npx react-native init AppName

I'm on node v14.17.1.

The startup script also says: success Successfully launched the app on the simulator

What am I doing wrong?

I had the same error because I was running on node v10.

After switching to node v14.17.5 (npm v6.14.14) via nvm, it solved the issue. Can you verify you are really on v14.17.1?

For me, I tried using node v14.17.5 and it didn't work. I removed:

static HttpError = HttpError;
static NetworkError = NetworkError;

from node_modules/metro-config/node_modules/metro-cache/src/stores/HttpStore.js and it worked.

Can use patch-package as well:

yarn patch-package metro-config/metro-cache
