react-native - React Native 升级失败 : fatal: working tree '.' already exists

Question

我尝试使用这些 instructions 将 React native 版本从 0.41 升级到 0.44 ，但我得到了这个错误:

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

可能有人知道我做错了什么？

Answer 1

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

为了升级工作，我必须删除 node_modules 并清理 yarn 缓存。

1) 删除 node_modules:

rm -rf ./node_modules

2) 清理 yarn 缓存

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

yarn cache clean 

我不确定它是否可以只运行删除 .tmp

3) 运行 yarn

4)再次运行升级

react-native-git-upgrade

注意:我的升级是从 0.51.0 到 0.53.3
