我尝试使用这些instructions将本机版本从0.41升级到0.44，但我收到此错误：

Note: checking out 'project-snapshot'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 4c8828d... Project snapshot

可能有人有任何想法我做错了吗？

Answer 1

我尝试了几个yarn + react-native-git-upgrade，但它对我不起作用

要进行升级工作，我必须删除node_modules并清理纱线缓存。

1）删除node_modules ：

rm -rf ./node_modules

2）清洁纱线缓存

rm -rf /Users/<myUsername>/Library/Caches/Yarn/v1/.tmp

yarn cache clean

我不确定是否只能删除.tmp

3）运行 yarn

4）再次升级

react-native-git-upgrade

注意：我的升级是从0.51.0到0.53.3

Answer 2
