Question

直到现在，我一直没有遇到使用“ create-react-native-app” cli命令创建react-native应用程序的任何问题。它没有创建它创建的普通ios和android文件，而是仅创建了node_modules，package-lock.json和package.json文件。下面是我运行命令后返回的输出。

    $ create-react-native-app Rdx
Creating a new React Native app in /Users/apple/Documents/Vscode/Redux-Testing/Rdx.

Using package manager as npm with npm interface.
Installing packages. This might take a couple minutes.
Installing react-native-scripts...

npm notice created a lockfile as package-lock.json. You should commit this file.

在此先感谢您的支持！

Answer 1

这是因为react-native-scripts使用的create-react-native-app软件包较旧，现在您的create-react-native-app版本将是version: 1.0.0。

更新程序包。

npm install -g create-react-native-app

现在create-react-native-app的版本将是2.0.2。

您现在可以创建自己的应用了。

create-react-native-app Rdx

您可能会要求安装expo-cli说Y。

create-react-native-app 2.0.2中的另一个好处是您可以创建blank或tabs应用。使用箭头键在终端中选择您喜欢的应用。

Answer 2

您使用的create-react-native-app版本很旧。它使用react-native-scripts代替Expo SDK。

您需要使用正确版本的react-native-scripts。您可以通过在使用create-react-native-app创建新项目时指定正确的react-native-script版本来做到这一点。要找到正确版本的react-native-scripts，请首先使用以下命令找出create-react-native-app的版本：

create-react-native-app --version

下一步，查看create-react-native-app和react-native-scripts的变更日志。

选择一个版本的react-native-scripts，它与您的create-react-native-apps版本大约同时发布。

然后，在使用create-react-native-app创建新项目时，指定react-native-scripts的版本。例如：

create-react-native-app --scripts-version 1.4.0 project-name

无法使用“ create-react-native-app”创建新应用
