我对Expo和 React Native还挺陌生的。我有一个为iOS和 Android编写的应用，想把它部署到Expo上，以便在外部手机上安装进行测试。

我是在Windows 11机器上运行构建命令。

我已经通过以下命令部署了iOS版本：

eas build --platform ios --profile preview

这里出现了一个问题，提示.xcode.env文件的编码不正确。把该文件改成正确的Linux编码后就修复了错误，现在我已经能够部署到Expo并在iPhone上安装。

我正在尝试对Android使用同样的方式，命令为：

eas build --platform android --profile preview

在这里，构建在 Run gradlew 步骤失败，具体错误如下：

我尝试使用 clear-cache 参数运行此命令，希望能对 node_modules 进行一次全新安装。

以下是我的 eas.json 文件：

{
  "cli": {
    "version": ">= 16.19.2",
    "appVersionSource": "remote"
  },
  "build": {
    "development": {
      "developmentClient": true,
      "distribution": "internal"
    },
    "preview": {
      "distribution": "internal",
      "android": {
        "buildType": "apk",
        "gradleCommand": ":app:assembleRelease"
      }
    },
    "production": {
      "autoIncrement": true
    }
  },
  "submit": {
    "production": {}
  }
}

应要求，以下是我的 package.json 文件

解决方案

正如前面的评论所提到的，问题在于新版Expo和 React Native中，hermesc的可执行文件不在默认位置，而是在node_modules/hermes-compiler下，因此我需要更新build.gradle和 gradle.properties文件。

大致如下：

android/app/build.gradle

hermesCommand = new File(["node", "--print", "require.resolve('hermes-compiler/package.json')"].execute(null, rootDir).text.trim()).getParentFile().getAbsolutePath() + "/hermesc/%OS-BIN%/hermesc"

android/gradle.properties

hermesCommand=../node_modules/hermes-compiler/hermesc/%OS-BIN%/hermesc

后来还出现了很多其他错误，这些是由于某些react-native包的版本不匹配所致。一旦这些问题修复，构建通过，我也能够安装应用。

不过，一打开应用就会直接崩溃。这是另一个问题，我现在正在调查，但上面的说明已经解决了我最初的问题。
