错误：未安装“反应本机”。请在项目目录中运行“npm 安装”

Question

只是按照facebook.github上的说明进行create-react-native-app首先得到的:react-redux 5.0.6需要react@^0.14.0 || react@^15.0.0-0的对等体....然后我卸载了react-redux，得到了这个...

这里是包.json

错误启动包装机

错误:未安装React native。请在您的项目目录中运行npm install。上午1:23:51:启动打包程序时出错:错误:无法启动项目。请修复错误并重新启动项目。at E:\ xdl \ src \ project . js:1126:11 at next(native)at step(E:\ react-native \ hello-world \ node _ modules \ xdl \ build \ project . js:1504:191 at E:\ react-native \ hello-world \ node _ modules \ xdl \ build \ project . js:1504:361 NPM ERR！代码ELIFECYCLE npm错误！错误1 npm错误！hello-world @ 0 . 1 . 0 start:react-native-scripts start NPM ERR！退出状态1 npm错误！npm错误！hello-world@0.1.0启动脚本失败。npm错误！这可能不是npm的问题。上面可能有额外的日志输出。

npm错误！此运行的完整日志可以在以下位置找到:npm ERR！c:\ Users \ Jawad Ul Hassan \ AppData \ Roaming \ NPM-cache _ logs \ 2017-09-08 T20 _ 23 _ 51 _ 654 z-debug . log

我可能犯了什么错误，或者有什么建议可以正确地做这件事？

npm安装后得到这个

Answer 1

您可以在第一行看到，没有找到git

==

先安装git。

Answer 2

这可能是因为 npm 版本 v5 所以

npm5仍然很麻烦，请使用yarn或npm4版本。

npm i -g yarn
npm i -g npm@4

或者确保从项目目录安装npm。这也是你得到这个错误的原因之一

npm i

Answer 3

当我安装react-导航包时，出现了错误。我已经修复了我的问题。

1. 删除node_modules、包锁。json
2. 运行“纱线安装”
3. 运行“npm启动”
