Answer 1

您必须按照错误日志所述迁移到anroidx。试试这个。

android / gradle.properties

android.useAndroidX=true
android.enableJetifier=true

Answer 2

放入

android.useAndroidX=true
android.enableJetifier=true

发送到您的gradle.properties。

然后安装jetify：

yarn add jetifier --dev
npx jetify

然后在package.json上将jetify添加到您的postinstall-Script中：

"scripts": {
  ...
  "postinstall": "jetify"
  ...
}

如果仍有@postinstall条目，则仅在末尾添加&&。如果您在安装后仍然有patch-package的示例： „patch-package && jetify“

至少，运行yarn install可以解决问题。

如果您在使用jetify时遇到问题，可以使用jetify -r

撤消node_modules-Package中的更改。
