npm start原因错误未安装React native

Question

I want to learn React Native and start from [Facebook Github][1], So have installed the node.js V8.114 , then run below command on command prompt

npm install -g create-react-native-app

create-react-native-app AwesomeProject

cd AwesomeProject
npm start

Everything went right, but when I run the npm start , this error caused:

Error: React native is not installed. Please run npm install in your project directory. 16:36:21: Error starting packager: Error: Couldn't start project. Please fix the errors and restart the project. at C:\\xdl\\src\\Project.js:1329:11 at Generator.next () at step (C:\\Users\\Riazati\\AwesomeProject\\node_modules\\xdl\\build\\Project.js:1735:191) at C:\\Users\\Riazati\\AwesomeProject\\node_modules\\xdl\\build\\Project.js:1735:361 at npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! AwesomeProject@0.1.0 start: react-native-scripts start npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the AwesomeProject@0.1.0 start script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Can anyone help me?

Answer 1

确保您已更新npm install -g npm@latest删除文件夹，然后重新运行构建过程

Answer 2

尝试运行npm install ，就像错误消息告诉您那样。

Answer 3

cd到项目后，尝试运行“ npm install”或“ yarn”，然后可以尝试运行“ react-native run-ios”或“ react-native run-android”

Answer 4

Deleting node modules and then run npm install or yarn install worked for me!! Cheers.
