Description

npx react-native upgrade failed to upgrade my react-native app from 0.62.2 to 0.63.0.

info No version passed. Fetching latest...
info Fetching diff between v0.62.2 and v0.63.0...

warn Excluding files that exist in the template, but not in your project:

error Excluding files that failed to apply the diff:
  - MyProject/android/gradlew.bat
  - MyProject/ios/Podfile
  - MyProject/ios/MyProject.xcodeproj/project.pbxproj

1. Zero files changed by the upgrade command
2. Not all the files listed on the upgrade-helper diff appear in the “failed to apply the diff” list
3. 2/3 of the problematic files also appeared to cause problems on a brand new react-native app

Reproducible Demo

To sanity-check, I did the following:

react-native init --version="react-native@0.62.2" ReactNativeUpgradeTest
cd ReactNativeUpgradeTest
react-native upgrade

And I got this output:

I do see changes in this case, but it still has errors applying the diff to:

• android/gradlew.bat
• ios/ReactNativeUpgradeTest.xcodeproj/project.pbxproj

If you want to upgrade with React Native CLI but you don’t use Git# While your project does not have to be handled by the Git versioning system – you can use Mercurial, SVN, or nothing – you will still need to install Git on your system in order to use npx react-native upgrade. Git will also need to be available in the PATH. If your project doesn’t use Git, initialize it and commit:

git init # Initialize a Git repository
git add . # Stage all the current files
git commit -m "Upgrade react-native" # Save the current files in a commit

After you finish upgrading you may remove the .git directory.
