React-Native构建错误（开发服务器返回响应错误代码：500）

我正在尝试使用 React Native 开发一个新项目。但我对 React Native 知之甚少。我正确地完成了所有设置。但我无法从模拟器构建。你能帮助我吗？我收到这样的错误：

The development server returned response error code: 500

我遇到过同样的问题。

我之前的反应本机版本是

C:\WINDOWS\system32>react-native -v
react-native-cli: 2.0.1
react-native: 0.56.0

然后我卸载react-native

C:\WINDOWS\system32>npm uninstall -g react-native-cli
removed 41 packages in 3.999s

然后我安装了react-native版本0.55.4

npm install [email protected] /cdn-cgi/l/email-protection

再次安装react native cli 1.2.0

npm install -g [email protected] /cdn-cgi/l/email-protection

然后创建react-native项目的安装就可以了

react-native init --version="0.55.4" myprojectname
