我刚刚使用初始化命令create-react-native-app开始了我的项目，并安装了所有前提条件。

我试图进行搜索，并且人们正在谈论升级react-native，但是当我尝试“ react-native-git-upgrade”时，我的“ package.json”版本出现了错误。

    git-upgrade info Check for updates 
git-upgrade info Read package.json files 
git-upgrade info Check declared version 
git-upgrade info Check matching versions 
git-upgrade ERR! An error occurred during upgrade: 
git-upgrade ERR! Error: react-native version in "package.json" (https://github.com/expo/react-native/archive/sdk-30.0.0.tar.gz) doesn't match the installed version in "node_modules" (0.55.4).
Try running "npm install" to fix this.

当我npm install进行任何更改时，我尝试删除自己的node_modules目录，并使用npm install创建一个新目录，但是它没有变化。

我在Ubuntu上，几天以来一直在为此苦苦挣扎...

Answer 1

我认为这些步骤将为您提供帮助。

转到您的项目目录并运行此命令[Ubuntu：cd android && ./gradlew clean]
假设您位于ubuntu的android目录[rm -rf build中，请从android目录中删除构建文件夹
如果此步骤未产生任何结果，请执行步骤[1,2] 然后删除 node_modules 目录并在之后运行npm install 在项目的根目录中跟随[1,2]。
最后，从项目根目录使用此命令react-native run-android。

React-Native运行android错误Java不是增量的，react-native升级版本与node_module不匹配
