试图升级本机，获取令人困惑的信息

Question

我正在遵循以下指南：https://facebook.github.io/react-native/docs/upgrading.html

然而，我得到了这个打印出来：

> react-native upgrade 0.59
Scanning folders for symlinks in /Users/danale/Projects/engage-application.mobile/node_modules (18ms)
You should consider using the new upgrade tool based on Git. It makes upgrades easier by resolving most conflicts automatically.
To use it:
- Go back to the old version of React Native
- Run "npm install -g react-native-git-upgrade"
- Run "react-native-git-upgrade"
See https://facebook.github.io/react-native/docs/upgrading.html
Upgrading project to react-native v0.53.3
Check out the release notes and breaking changes: https://github.com/facebook/react-native/releases/tag/v0.53.0
.babelrc has changed in the new version.
Do you want to keep your .babelrc or replace it with the latest version?
If you ever made any changes to this file, you'll probably want to keep it.
You can see the new version here: /Users/danale/Projects/engage-application.mobile/node_modules/react-native/local-cli/templates/HelloWorld/_babelrc
Do you want to replace .babelrc? Answer y to replace, n to keep your version:

我扼杀了这个过程，因为我搞不懂为什么它认为我想升级到我已经拥有的版本？

如果我尝试输出中的建议，就会得到以下错误：

您没有正确使用react-native upgrade命令。您所链接的指南指出，您需要：

1. 升级react本机依赖关系。因此，在本例中，您需要运行：npm install --save react-native@0.59
2. 运行升级命令：react-native upgrade
