react-native android 项目未找到错误

Question

I am trying to create a react-native project using react-native cli. Command I used to create project

• npx react-native init test

After this if I try to run this app by

• cd test & npx react-native run-android

But I get this error:

error Android project not found. Are you sure this is a React Native project? If your Android files are located in a non-standard location (eg not inside 'android' folder), consider setting project.android.sourceDir option to point to a new location.

I have android, ios folder in root project and node version is 16.15.0

This is my project json:

 { "name": "test", "version": "0.0.1", "private": true, "scripts": { "android": "react-native run-android", "ios": "react-native run-ios", "start": "react-native start", "test": "jest", "lint": "eslint." }, "dependencies": { "react": "17.0.2", "react-native": "0.68.2" }, "devDependencies": { "@babel/core": "^7.12.9", "@babel/runtime": "^7.12.5", "@react-native-community/eslint-config": "^2.0.0", "babel-jest": "^26.6.3", "eslint": "^7.32.0", "jest": "^26.6.3", "metro-react-native-babel-preset": "^0.67.0", "react-test-renderer": "17.0.2" }, "jest": { "preset": "react-native" } }

I was facing the same issue too so i've created a thread on r/reactnative and someone kind provided a solution. Not sure why, but it works for me. The solution is:

1. delete node_modules
2. add this to package.json: "resolutions": { "glob": "7.2.0" }
3. install node_modules with yarn or npm

Answer 2

The issue comes after glob@7.2.2 was released. Follow the following steps and recompile the project.

1. Clear node_modules
2. add this to package.json "resolutions": { "glob": "7.2.0" }
3. Reinstall node_modules with npm install

If this not work try this command

" yarn add glob@7.2.0"

Answer 3

Update on the tagged date. I had the same error on a new install. version 0.69.0 had problems finishing the install. Suggestion from github that I install new project with the previous version

npx react-native init ProjectName --version 0.68.2

I fixed mine by using cortinico's answer from https://github.com/facebook/react-native/issues/34055#issuecomment-1165887713

The issue is caused by having some globally installed Yarn/NPM packages which is not generally recommended.

Depending on the commands you installed in the past with -g, you should be able to cleanup your environment with a combination of those commands:

yarn global remove react-native
yarn global remove react-native-cli
npm uninstall -g react-native
npm uninstall -g react-native-cli

Make sure the global packages are clean with:

yarn global list
npm -g list

(check that nothing react-native related is available in those lists).

Afterwards you can then simply install using:

npx react-native init PROJECT_NAME
