react-native run-android通过在android仿真器中的消息中保留一条消息来终止。消息如下

无法加载脚本。请确保您正在运行Metro服务器，或者已正确捆绑了软件包“ index.android.bundle”以进行发布。

我完全感到困惑，这是在做错什么。

编辑：添加错误屏幕截图

我今天更新了node，但出现此错误：

error: TypeError: Cannot read properties of undefined (reading 'transformFile')

除此之外我没有做过任何不寻常的事情，所以我不知道该分享什么。如果我遗漏了任何信息，请评论，我会添加它。

在构建终端时也会抛出此错误：

1. 我刚刚安装了node.js和cli

   • 安装的node.js

   • 安装了react-native-cli

     npm -g react-native-cli
     

     Run Code Online (Sandbox Code Playgroud)

2. 并创建了一个“新项目”。

   react-native init new_project
   

   Run Code Online (Sandbox Code Playgroud)

3. 在“ new_project”目录中，我很疲倦地查看Metro bundler是否运行良好。

   react-native start
   

   Run Code Online (Sandbox Code Playgroud)

4. 但是该命令给了我以下错误，并且Metro无法启动。有任何解决此错误的线索吗？（我正在使用Windows 10 OS。）

   • 命令： C:\projects\new_proj>react-native start

我正在本地环境中克隆现有的react本机应用程序,但每次运行'react-native run-ios'时都会出现以下错误:

我试图直接从终端运行发布版本,我没有找到一个选项来做到这一点.

从XCode开始,需要做的是:

产品 - >方案 - >编辑方案(cmd + <),确保您在侧面的"运行"选项卡中,并将"构建配置"下拉列表设置为"释放".

http://facebook.github.io/react-native/docs/running-on-device-ios.html#building-your-app-for-production

有什么选择可以react-native-cli做同样的事情吗？有点像react-native run-ios -configuration Release？

我的目标是生成一个不需要服务器运行的构建,例如提供给QA团队.

我今天升级到Xcode 10.2，因为升级无法react-native run-ios通过cli 运行：

react-native run-ios --simulator="iPhone X"

Found Xcode workspace a.xcworkspace

Could not find iPhone X simulator

Error: Could not find iPhone X simulator

如果我运行xcrun simctl list devices所有模拟器，则显示(Shutdown) (unavailable, runtime profile not found)：

iPhone X (7AADFA50-7B57-4A40-8434-9A86F345D7ED) (Shutdown) (unavailable, runtime profile not found)

自从将xcode升级到10.2以来，还有其他人遇到过RN的问题吗？它仍然可以通过Xcode ..起作用，但这意味着打开Xcode。

在 React Native 中，当我尝试在 Google 控制台中获取 Google GPS API 密钥时，我看到了包名称和 SHA-1 密钥，我在 React Native 中从何处获取 SHA-1 密钥

如何在 React Native cli 中获取 SHA-1 密钥？（不在世博会）。

我最近在全球范围内安装了 React Native cli。当我尝试使用react-native init projectnameor启动一个项目时npx react-native init projectname，它开始下载包并创建项目。完成后出现这个错误

    cli.init(root, projectname);
      ^

是什么导致了这个问题？

我按照以下链接开始使用react-native

React Native入门

我试图创建没有expo的本机应用程序，所以按照文档，我遵循以下命令

npm install -g react-native-cli
react-native init AwesomeProject

运行android命令后

react-native run-android

它给我以下模拟器错误

所以我用启动命令来运行Metro服务器

react-native start

这个命令给了我控制台另一个错误

我尝试在 react-native 中获取 Apk，但是它没有给我任何东西。Apk 文件中的 release 文件是空的，在 Gradlew bundle 发布完成后，它说

    Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/5.4.1/userguide/command_line_interface.html#sec:command_line_warnings

我找不到如何解决这个问题
